Swing Arm Conversion again!

[Panther]

I know this topic has been covered a few times before.
--------------------------------------------------------------------------

I am in 2 minds whether to convert my bike to a single sider or save and buy a s2r.

I am interested in fitting a S*R swing arm to my 750ie, as I might be able to get one quite cheaply. After having a quick look thought some old posts, I see it should just bolt straight on. (thanks ak)

what else would need to finish the mod?

-new rear wheel?
-rear break disk?
-break hose?
-sprockets/chain?

Thanks for the help,

Martin

[MagnaJeep]

You will probably have to change almost everything that you have listed,
and probably the exhaust too.

I'm very interested in this mod, as I would also like to know what needs to be done. ;)

[Capo]

I have a S4R swingarm, brake disk, caliper and shock available

[gary tompkins]

Sell the 750 and buy Albie's S4/S4R custom - lot's less hassle and instant single sider

Ex UKMOC Bike of the Year 2008 to boot ;)

[Albie]

Err yeah I was going to say unless you dont want a pillion. you will need as follows

Swingarm
Hub and brakes
Footrests/ gearchange and brake
Pillion hangers if so you will need to make up new mountings and weld to frame
Rear Wheel
Rear shock and if its an s4r one you need to mod frame to clear
Exhaust headers and system as they are totally different lengths
A new chain
If you do not intend to pillion you may be able to use old hangers or rearsets but the exhaust may have to be a custom made or an underslung system.

Dont be put off it easy enough but you have to source the parts.

[Panther]

Modding my bike might be an effort, but for me it's definitely half the fun. If I can get the parts at the right prices. I will source the parts over the summer, for a winter rebuild :-)

I just not keen on a bike with plumbing so the S4/S4R is out the quest.
----------------------------------------------------------------
Abbey you said,

'a rear shock and if its an s4r one you need to mod frame to clear'

~ so I need a s*r rear shock, preferable from a s2r so I don't need to mod the frame. (is this a big mod?)

'Hub and brakes' ~ it's the centre bit of the wheel, holds the break too??

- already looking at rearsets for the bike, and don't have a big requirement for pillion hangers

- If I bought a s2r, I would fit a underslung system anyway (QD ex box or custom)

Am I correct in thinking a wheel from a 998 would fit too.

---------------------------------------------------------------------------------------------
Capo, if you could pm me with the price for the parts to see if it's in my price bracket, cheers.


Thanks all for the help,
I think I better start re-looking though some of your old rebuild posts abbey :-)

[Albie]

'a rear shock and if its an s4r one you need to mod frame to clear'

~ so I need a s*r rear shock, preferable from a s2r so I don't need to mod the frame. (is this a big mod?)S2r one is fine but non adjustable S4r is better. Basically Ducati crimpe the frame on the rear on one side around 2mm squashed on inside, I have pics of what I did

'Hub and brakes' ~ it's the centre bit of the wheel, holds the break too??Yes holds the brake

- already looking at rearsets for the bike, and don't have a big requirement for pillion hangers

- If I bought a s2r, I would fit a underslung system anyway (QD ex box or custom) Yes but you still need s2r headers to come down. They are either longer or shorter without looking. Standard ones can be modded if you know and exhaust specialist

Am I correct in thinking a wheel from a 998 would fit too.Yes it will fit

And yes you are correct in it is fun and you are capable and if you do rest assured you will be proud of your efforts.

[Albie]

Link to my post resurrected with photos redone. If you need more pics as I never posted all please pm me and I will either search or photograph s4 in more detail of the area you have concerns with.

So far I've managed to get a few bit from Capo,

Does any know if rear axle / hub from a 748/916/996/998 will fit into a S*R swingarm

Yes it should be exactly the same - but you can always check the part numbers with your ducati dealer (you'll be visiting them a lot over the next few months I imagine x)

You will also have to bare in mind that the speedo pick-up requires 6 pulses (bolt heads) for the regular swingarm ie monsters (inc the S4), whereas I believe the S2R/S4R only needs four pulses/bolts... on my Febur conversion kit, they mod the stock 916 rear disc with tabs to correctly space six ferrous bolts to drive the speedo pick-up.

Also, a 916 etc rear disc/caliper carrier is slightly smaller diameter than the S2R/S4R (although the caliper itself will fit) - so you'll need to use the correct disc for the corresponding caliper bracket.

Also, most 916/998s etc ran a 525 pitch chain and sprockets, so you'll need to factor in a 520 rear chainring (expensive - I'd get the Renthal combo). Alternatively you might be able to run a 525 chain and front sprocket? - but not sure the chain will line up on the swingarm slipper - not sure if the S4R runs a 525 or 520 chain like the S2R?

You are also likely to need a selection of shims for the swingarm pivot to get it spaced properly on your engine case as they all differ slightly (by a few thou).

Boy are you going to have fun...

[Panther]

Thanks for the help and advice JMo, I did not realise about the speedo pick, lucky my fathers an electical engineer so I hope he can figure that out.

I'm going to measure the engine casing and swingarm dia with a vernier calliper, so I should be able to machine some shims up for the pivot, rather than buying a selection of ducati shims to make them fit.

I have start downloading a few different Part catalogues. to make sure I've got all the parts before I start the rebuild. I've already got a rear disc, calliper and sprocket from a S4R (cappo) too.


below you see hub for 748 and S4R have a different part number :scratch:

748 part 13 (hub) 819.2.039.2A

[JMo]

Hi Panther - I can't see the pictures on my computer?

As for the shims, said the waiter to Mr Creosote - they are only wafer thin... like a few thou - you certainly won't be able to machine them - but they only cost a few pence each from Ducati... they are there to stop any side to side play in the swingarm...

xxx

[Albie]

They come in various sizes such as 1mm 0.50mm 0.10mm kind of thing. You do need some play but minimal. Dealers have them and they are not dear.

Early s4 has speedo on front wheel like mine did. Later with sweeping clocks rear wheel.


m900 m1000 s4 and s4r has 525 chain.

[Panther]

I've just added an attachment of the rear wheel pin from a 748 and S4R on my previous post.

The yellow parts show the parts I definitely need to buy (15 is the shims) I also need some snap rings (4). I hope to fire an email off tonight to my local dealer (Coventry) with a list of parts needed

http://ukmonster.co.uk/monster/attachment.php?attachmentid=12808&d=1246986471

15 852.1.001.1B Shim th. 1.8
15 852.1.002.1B Shim th. 0.2
15 852.1.003.1B Shim th. 0.1

I'm also planning on machining the end's of the pivot bolts, as I'm thinking of using 'ie' rearset rather than S*R style.

-----------------------------------------------------------------------------------------------------------------------
I'm right in thinking I can use the rocker assemble from my 'ie' the part numbers are all the same as the S4R apart from the suspension (already have a S4R suspension too)

[Albie]

I think you will find you can use the standard swingarm pivot spindle if you dont want to use the s4r hangers. They are only longer to have a thread to bolt them onto. You can reuse the circlips if you haven't damaged them of your old swingarm.

[Panther]

Thanks Abbe, you just saved me a couple ££'s and time. I see the circlips from the 620ie have the same part code.

The swinging arm I've got is covered in brown primer.............. I'm thinking of going back to stand metal finish. I feel red would might be to much with red wheels (still to buy)

I guess this is going to need alot of elbow grease and a few bit of sand paper to stip, maybe aluminium polish too?. Or should I wait and get it blasted when I go to get a rear wheel powder coated?

[slob]

The swinging arm I've got is covered in brown primer

it's not magnesium is it?

[Albie]

No I dont think it is magnesium. It sounds like the one I got offered as a spare from Sean . It looks flesh colour primer. Personally Panther I would either as JMO may say get it polished or get it powdercoated and they will automatically shotblast it anyhow. I was going to do mine red not senna tomato red. The wheels do look ok the same colour but I nearly went satin black which is quite a cool look.

If I can save you a few pounds that good.

[JMo]

...Personally Panther I would either as JMO may say get it polished or get it powdercoated and they will automatically shotblast it anyhow...

Hee hee - polished looks fantastic, but the S2R shape swinger would be even more of a bitch to keep clean...

Personally I'd get it shot blasted, then painted/powder coated in the some colour as the frame - whatever that is/the could you decide to do it...?

They are actually very hard to clean as nooks and crannies.And a not the smoothest of castings either as my powdercoater told me. Im actually glad M1100 one is satin black. Hides a multiude of grease specs.

[Trent]

below you see hub for 748 and S4R have a different part number :scratch:


The difference in part numbers could be the bolts...
The S4R hub (part 13) looks like it comes with 3 different bolts (11, 14 and 19), whereas the 748 hub has the same bolts. but they don't come with the hub...

[JMo]

Also, regarding the picture/diagram of the swingarm you posted up - be careful trying to use the original swingarm pivot bar - yes the circlips might be the same part number, but the 620/750 bar won't have the chamfer for the bolt 6 and nut 7 to lock it onto - so the whole swinger would onyl be hled on by the circlips - which is probably not a good idea!

Obviously when you use the S2/4R hangers and end bolts, these offer additional security with the flange on each end of the bolts in the hanger...

The Febur kit uses the original M620/750 pivot bar, but it also clamps around each end of it like the original double sided swingarm does... the S2/4R swinger has no clamps, just that wedge bolt, which is supplemented by the end flange bolts in the hangers.

I think you'll need the the correct S2/4R pivot bar, and to be honest - it's safest to use the S2/4R hangers and bolts etc, or some fancy billet alternative for the same bikes...

thats all that holds all monsters together. They have plastic bungs. Dont forget that they have clamp bolts too.

[JMo]

Jen

Yes - the double side swingarms clamp around the bar at each end with a slit and a pinch bolt, with a good inch width of metal all the way around to grab the bar.

The S2/4R swingarm doesn't have the slit/pinch bolts on each end - it's just a solid hole through the casting, and a single wedge bolt (single) part 6 & 7 locks the position of the bar... however, one presumes the flange on the end bolts is to to stop it sliding out either way incase that little part 6 bolt ever broke/fell out, as I doubt the circlips would hold up for long cranked over through Gerrards for example?

xxx

[Panther]

Interesting thoughts on the hangers end bolts (special scew, as named in the pats list) to support pivot bar. I could make some bolts and flange if needed, (small ones so they would not stick out so far). Or even drill a second pinch bolts hole in the swingarm :confused:
-I think the pinch bolt is just to stop pivot bar rotating and wearing the swingarm as there is bearing inside engine hole. And the circlips are there to stop the pitch bolt falling out due to vibration, even going round a bend I don't think there is much sideways force on them, as the bike is in balance (centripetal force)???

One of the reason why I was thinking of using 'ie' rear set,is because of the existing hanger bracket on the frame, which would be redundant otherwise.

--------------------------------------------------------------------------------------------------
It sounds like the one I got offered as a spare from Sean . It looks flesh colour primer thats the one! The casting are definitely not the smoothies too. I know Capo did alot of work on his, grinding and sanding to make it smooth.

I think you guys are right, power coating is the way forward :) Satin black looks good, but I don't think it goes with my colour scheme, maybe a satin grey or titanium to compliment the frame.

I'm thinking of powder coating the rear sprocket flange red too.

If I had alots of time on my hands I would probably go for a red frame and swingarm and grey/black wheel......(a mod for next year :p)

I've already got a DP 43 rear sprocket from Cappo's S4R, which is a 525 pitch. There for I'm guessing it will line up with the swingarm slipper. Does this mean a 525 Chain and Renthal front sprocket should complete the job nicely.



You will also have to bare in mind that the speedo pick-up requires 6 pulses (bolt heads) for the regular swingarm ie monsters (inc the S4), whereas I believe the S2R/S4R only needs four pulses/bolts... on my Febur conversion kit, they mod the stock 916 rear disc with tabs to correctly space six ferrous bolts to drive the speedo pick-up.

xxx

TBH, I don't know much about my speedo pick-up, and the modding involved to make my speed work. I hope it all becomes apparent when I get to it.


--------------------------------------------

I've finally got myself a rear Marchesini 5 spoke wheel from Italian Ebay, I paid a little more than I wanted to, but needs must! Hopefully it should not take to long to arrive so I can get it and the swingarm powercoated.

[Panther]

JMo my bikes been kept in a garage away from my home, but I finally understand exactly what you mean regarding the speedo pick up, :thumbsup: With my bike having 6 pick-up (bolt heads) where the rear disc it attached, and a S4R has 4 bolt heads.
Hopefully my farther can reprogram the input signal to be multiplied by 1.5 (=6) Otherwise, I'm looking at adding 2 dummy bolt heads but as they would not be evenly spaced, I guess it would make the speedo go a bit 'wavey'.

I though I would also post a few pictures of poor casting. Today I decided to spend an hour sanding the on worst area's. The who swingarm is going to blast and paint soon anyway.

The swing arm is made of two basic components the front is a casting and the rear appears to be an extrusion.
Heres mine after much filing to remove all the casting flash.

Now that's a proper job! :thumbsup:

I really like it how you have removed the beading, on the bottom part of the swingarm, it really cleans up the lines. I don't think I have the patients to remove it and could very easily f* it all up!

[Panther]

Whilst being hungover yesterday I though it would be a good idea to start dismantling the rear. I got to say I had a pretty successful afternoon, removed the hangs, exhausts inc headers, front sprocket and pivot bar.

This morning I removed the swinging too and lined up the new single sider! Personally I think it's looking good :-) But I need to change the suspension unit and mod the frame to make it fit.

I also have a small concern that is very little clearance on the exhaust headers, although I did not fit it properly.

[Panther]

The alignment/spacing of the new swingarm seem good, I'm currently using my existing washers (will get new ones from the dealer). Although I need to check the tolerances with feeler gauges.

I did say the rear exhaust will either have to be modified or you need an s2r rear header. Not a big deal just need to find a man who can or someone whose change to full system on s2r. Have you gone for the remote piggy backed rear shock then.
Also I see you have 3 spoke brembo wheels and I thought you was looking for 5 spoke marchesini rear. You could have picked up 748/916 one easier.

Looking good though and seems very familiar. Hope your enjoying it.

3 spoke brembo are my old wheels. I'm keep the front one on for now. Just got an email from the guy it Italy saying he's posted them today (......he's only 4 days late to post them) Apparently from a 748/916/996/998??? but looks like an S*R wheel.


http://cgi.ebay.it/ws/eBayISAPI.dll?ViewItem&item=350219480043&ssPageName=ADME:X:AAQ:IT:1123

[Albie]

Yes 5 spoke were made I think for the late 748 and 996/998/s2r/s4r/multistrada rear only but fit all including the one I had which was from a multistrada.

[Panther]

I'm still awaiting deliver of the rear spindal, when I realised I not got the hub :(. As I need to get a few bit and bobs from the deal I though I would enquire how much a new hub would cost OVER £700!! :eek: and rear break bracket for £90!

I'm now kicking my self as my last minute bid on ebay did not entire, On this complete assemble ........

On a plus I got an email the exhaust people who said they will mod my original heads.

I've not done much work on the bike over the last 2 days, today I checking the fit of the new rear suspension (S4R). I was expecting there to be clearance issues with the frame, but there appears to be a 4mm gap. ??? Albie:scratch:

http://lh6.ggpht.com/_9v5WXNjIDSo/Sl43mfQW3DI/AAAAAAAACCI/RMOArYwrpms/s512/P8140216.JPG


I was also expecting the S4R shocks to be different lengths to my original, I guess this means you could use an 'ie' shock with the singlesider if you wanted to. However I understand S4R has a better shock, being more adjustable.

http://lh3.ggpht.com/_9v5WXNjIDSo/Sl43ei2OdzI/AAAAAAAACBw/29xXyOq1GGk/s512/P8140193.JPG

I will be flogging to old shock soon too

[Albie]

The clearance issue. Right. When I did my mod I got told that the s4r had a side mounted reservoir. Okay I said and ...... Well they modified the frame on ALL s4r/rs to allow for a gap to pass safely. I did the same as you and still have the pics. It was around a 1-2mm clear. Now this gap is when its not under any load or any sideways stress. That shock absorber will flex sideways and is why I did the same as I was shown and recommended. I would not have taken any risks with my pillion as well with a clearance issue or the fact it could rub the paint or need to be modded after the powdercoat.

The choice is yours and its also down to the shimming and play in the swingarm which you just centred.

Also I think you need to raise the swingarm up and relook a bit higher up as if it was loaded. Dont forget the frames can be slightly different. These are made by italians by hand.

Yes the shocks are the same other than my old s4 one was a definate NO NO.

Heres my pics from my original posting
Yes shocking news. The s4r shock does fit the s4 straight in. Only thing is at the point to the rear where the frame tapers in to the tail its has only 1-2mmmax clearance. Thats not enough in my view if the shock flexes sideways which it can do. They aren't that rigid. Well anyhow its easy enough to put a clearance in the frame. GT mate you free asap ?

[Panther]

When looking at the clearance, I did make sure 2 biger shimes were in place, so swingarm was centred
I will probably rap 2 or 3mm thickness of masking tap round the frame. This way I can check to see if there an rubbing / clearance issue whist riding, and will mod the frame if this occurs.
I do agree it's right to be on the safe side. The last this I want is reservoir rupture on the frame

See I just reckon your lucky. Every engine can technically be different. Mine was an s4 with an alloy swingarm. There were two shims per side. I cant say exactly how thick but I thick around 0.60mm per side.
As you can see by my pics its closer than yours by mm's and that what you need. I think you maybe lucky and thats good. If you dont have too mod its great news and you can sigh a breath of relief. Just make sure that your happy and take a second opinion of someone else too who can see the clearance under load as such.

JMo my bikes been kept in a garage away from my home, but I finally understand exactly what you mean regarding the speedo pick up, :thumbsup: With my bike having 6 pick-up (bolt heads) where the rear disc it attached, and a S4R has 4 bolt heads.
Hopefully my farther can reprogram the input signal to be multiplied by 1.5 (=6) Otherwise, I'm looking at adding 2 dummy bolt heads but as they would not be evenly spaced, I guess it would make the speedo go a bit 'wavey'.

Good to see the project progressing nicely!

I agree with Albie that it's probably best to mod the frame around the shock anyway 'for safety' - although I can see why you would be reticent, especially if you can get away without repainting the frame? - you could just give it a whack with a lump hammer x

As for the speedo pick up - I'm not sure you can reprogramme the ECU but I might be wrong... the Febur kit comes with a modded disc that has four tabs and uses two of the existing bolt holes with ferrous bolts, and the other two with stainless that don't pulse the magnet - thus you get pulses from six evenly spaced ferrous bolts, rather than two oddly spaced 'extras' that might give a wavey pulse pattern as you surmise...

Thanks for info Jmo, originally I was thinking of using 4 ferrous with oddly spaced 'extras'. Thats a much better idea. I was not planning on reprogramme the ECU but add a small electric box before it and there changing the imput signal. ( At the min this the the least of my worries :()

So for the last week I've do absolutely nothing on my 'conversion' due to being bussy with other commitments. But I'm starting to get a little bit peeved that my wheel has not arrived from Italy, it's been over 2 weeks now. I emailed to the seller on Friday and he tell me the shipment has no tracking number.

On Sunday I did manage to pick up hub from a 916/996 with all the spacers and nuts etc. It all appearers in good condition and bearing are very smooth too. I was now looking forward to making a little bit more progress on the bike.

Today I went over to do a bit more work on the bike (and take a few photo's of other bits I'm selling)........... I manage to fall over at the first hurdle :confused: the new hub has shrunk in the the wash or am I being an idiot and missed something (bushing of some kind???)

Anyone know the OD of a S*R hub? I know the 916/996 hub is 98mm. The ID of the swingarm mount is ~ 103-105mm (should = OD of hub:scratch:)

http://lh6.ggpht.com/_9v5WXNjIDSo/Sm3VjH4gnHI/AAAAAAAACQU/8gIIsJsrrE0/s512/P8260239.JPG


So what my next step???? add a custom bushing, start selling bit on ebay............. :dizzy:

[Kato]

Just been out to measure S4Rs hub and it is 4.1318" or for those that work in French 104.94mm

[Panther]

Thanks Kato, that is a bit of a bugger about my hub!

This link shows my problem. According to this ebay item, S4r 748 996 998 all use the same hub

[JMo]

Sorry to hear that Panther, and it looked like a really nice one as well!

I never would have suspected that - Ducati are renowned for using the parts-bin when building new bikes... I never imagined they would have changed the diameter of the hub...

It is probably best to try and find the S2/4R version anyway, as I know the brake hanger plate is a different size/shape (and has the hole for the speedo pick up to sit in), and also I believe the S2/4R rear disc is slightly larger diameter than the 916 etc sportsbikes - worth remembering if getting an aftermarket disc.

I've already got a 996 and s4R rear disc, yer the 996 one is smaller. I guess I really need to source a S*R hub but I don't think is going to be so easy or cheap............A new one at £740 is not a option.

These project always take longer and cost more hey, but I'm still staying positive.

[Albie]

maybe part/ex with kato if he has one to offer. i was not buying in bits like you. i started with the whole swingarm assembly and from there on got bits. unbelievable they make 2 sizes. i guess over the years they have beefed up with horsepower and have grown the specs. i wonder if not a multitrada 1000/1100 is the same.

sleeving would be cheaper than oem part. but not cheap. and has to be split.

[Panther]

Do you think this would fit???

848 swing arm :scratch:

As of Sunday I'm going to be away working in sunny Libya for the next 5 weeks! Hopefully I will get the chance to scour ebay. So I will can have the hub / remaining parts ready for when I come back.

O, I also hope my rear wheel will turn up too, I only won it on ebay 3 weeks ago now.

p.s any one who is interested in this swing-arm, I will show them where they can find it. Also found a link to Ducati Monster 1100 swing arm too

[Panther]

It's been a long time since I've done any work on my bike..... that's mainly down to waiting for a 2nd swingarm from America and work abroad for 7 weeks.
I though if I'm going to do all the hard work of fitting the swingarm I might as well get in a custom colour, So last week I decided to go a head with getting it powdercoat @ profinish in Nuneaton

Yesterday I went to collect my parts, TBH I'm very happy finish and cost, £40 for the swingarm and sprocket cover.

Although the photo's aren't the best (all taken with the flash) In hindsight I wish the swingarm was a colour match with the engine casting, or even the tank. Originally I just wanted to go for a mat charcoal grey. The red on the sprocket is not a perfect colour match with my wheels but pretty close. Overall I'm happy with the results.

It's a bit Grey!

Today I did a mock up of how the swingarm will look on the bike. I've also been looking into modding the speedo pick-up as my bike uses 6 point per revolution and not 4 points as st on an S*R. Initially I planned to add an aluminum ring to the disk brake to house these extra steel 'pick-ups'. But I've decided I'm going to add a 'smart box', which will change 2 impulses from the 'pick-up' into 3.

Yer the rear wheel is not on properly secured, and I need to fit the rear break. I also need to over the front wheel to a 5 spoke....... The next step is to get some exhausts then a service!

[uksurfer]

looking good, i like it! :)

[Chass]

That looks the nuts, I agree with you the swinging arm would maybe look better ether the same as frame or cases great job anyway, not a big deal to repaint or powder coat the swinger.

[Panther]

It was not an easy task choosing the colour. When I was down at the painters I did not have the bike to hand, and was only looking at small little colour samples, it's difficult. I was also limited by the number of stock colours they had at the paints unless you want to pay $$.

The paint work on the frame also has couple of small chips, maybe next year, I will get them both re-powder coated. I just want to get her finished now TBH.

When I take some more pics of the bike in natural light it should look better too.


p.s Do I fit my Red chain, I think it might be a bit OTT

[Panther]

Today I've been looking at fitting the chain and rear break cable.

I've had a few issues with rear break cable being to long because of change in rearsets. I've managed to re-route the cable, but this means it now runs close to the bottom of the suspension. I'm sure it will not interfere with the suspension, but I'm concern is it rubbing on the swing and wearing the paint, what do you think? ~ the photo's are pretty crap, hopefully you get the idea.

I'm also looking at the possibility of fitting a hel braided cable, so I can get it made to length. (they seem to be pretty popular on here)

Any opinions on the Red chain........ I think it Gold is the way to go!!! I know it's my bike but I appreciate other peoples feedback.
I still need to get a link for the chain, but I think it's to short anyway. :(

I'm also getting clearance issues with the tire valve and the rear brake. I think it needs to be changed to a 90o valve like on the front wheel
