It's always the simple jobs that take the longest...

The clutch has been slipping on my bike so I ordered up some new friction plates to throw in. But when I opened it up I was greeted by my "not-so-dry" clutch:

Bugger.

The big oil seal is easy enough to change, and not that expensive, but it's annoying to have to do it.

Ha, thanks Nasher.

I tried getting a list of all possible seals and o-rings last night from a parts catalogue. For a few pieces of rubber they add up pretty quick.

There was only the big one and two at the slave cylinder end labelled oil seal. But I was wondering is it worth just swapping out the o-rings and bearing if it’s apart anyway?

If you're lucky, it might just be the small oil seal in the clutch end of the shaft.

Easy to replace as it doesn't need the side casing removing.

Macflurry · 07-01-2019, 02:50 PM

Thanks Dukedesmo.

To be on the safe side I've ordered a set of the oil-seals and all the o-rings I could see to give it a relatively cheap refresh.

I'll play with the bearings as they come out and order them if needed as they were bumping the cost up. Knowing they're swapped out is another job done for peace of mind.

I have heard that the big oil seal behind the clutch is extremely easy to damage when fitting. I think there is a tool for easing it into place without nicking it?

BTW have you moved to the North Norfolk coast?

I have such a tool, Jeff made it for me.

Some years ago I did some work for a US company Sealol. Talking to their service department, they told me that 99% of failures were due to damage during installation.

That's the way I'd look at it, whilst you have it apart.

No mate, Gloucester. I've noticed Sat Nav and Google Maps have a bit of a fit when trying to work out which Blakeney to use.

Do either of you guys have a pick of the tool for the seal?

Mr Gazza · 07-01-2019, 07:28 PM

Well! I didn't know there where two Blakeney's.

Sorry I don't have a picture..Just a notion that the tool exists.

There is a pic in the manual, it was from that pic I made mine

I used to really like the A48 through Blakeney [Gloucs.] but they seem to have ruined it over the last forty years.

It's a nice route but I drive along daily and wonder who on earth thought some of its features were a good idea! They usually involve blind summits into junctions or merging lanes, again after blind summits, when the road only opened up about 50m earlier!!

The big seal behind the clutch drum went on my 1997 900 not long after I bought the bike (in late 1999) from my mate who put less than a thousand miles on it in two years- an adage to Ducati's don't like being laid up without being used.

If I remember correctly Ducati say it can't be removed without splitting the cases but good ol' Haynes say otherwise and I employed their method of carefully removing it by edging round it with a thin flat screwdriver and fitting the new one with a suitable sized socket as a drift.

Over the years I've replaced the O rings on the push rod a couple of times and the bearings in the pressure plate (just for peace of mind while doing other jobs) and never had an issue with any of them since.
