Yes, TSR does sound like a competent firm - I think we should understand that there is potential for problems with embedded blast material with incompetent firms so we should only use firms with a pedigree like TSR.

The guy I spoke to today sounded like a decent engineer who knew what he was doing but anybody can buy a vapour blast kit, get themselves a website and start blasting with no experience and with no knowledge of finishing the component.

This is interesting stuff to me - and I've learned something from this thread. I am going to get a microscope and it will be interesting to compare pictures of my dry blasting with yours so we know what embedded media looks like.


.......this thread has got a long way to go

Ref oil pump: as always one thing leads to another - if you hadn't blown the engine, that pump would have carried on working like that and would supply enough oil. The largest contribution to low oil supply would be end clearance of the gears in the housing rather than the scoring.

Obviously the oil pump does have a hard life because it only has the mesh screen to filter debris so all pumps can get some scoring - but if we don't dismantle engine we don't see it. The big disadvantage of sharing the engine with the gearbox is that it produces a lot of debris that all has to pass through the pump to the filter.

Would I replace that pump? - definitely!

I suspect blowing the engine is what caused the scoring as most of the smaller fragments of big and shell will have been through there on the way to the filter.

So the engine carried on running? - that deep score looks quite big for the mesh to pass so is the mesh filter damaged? I haven't looked at mine for over a year but thought the mesh was finer.

Yes, sadly I'd just passed the pit entrance when it went and limped round for 2.5 miles, trying to keep off the racing line, to get to safety.

Amazing it held together for that long - these engines are good!

Bit of a break for the UKMOC Weekender but I managed to get down to Moto Rapido on Saturday morning and pick up the gearbox, which looks stunning after ultrasonic 'rumbling'. I hope it works as well as it looks.


I spent most of Sunday prepping the crancases. Solvent cleaned, then with detegent, rinsed and dried with an airline and in the oven, finally several hours masking them up.


I got home in time to spray them this evening


The Hycote VHT paint isn't as metalic as I'd have really liked but a bit late now... they're ready to cure as soon as I can find a 'food free' window to use the oven.

you're putting my hamerite brush job to shame with those cases Rob! Looks ace!

Is this why take away was invented?

[J.P]

that looks a fine job of masking

Now it's getting interesting - I'm looking forward to main bearings and crank shimming so plenty of pics on this please.

Looking good.

I bought a second hand 749s oil pump which looks fine inside, no advantage over M1000, they're the same part no. but it was cheap and available.


A huge collection of belts, bearings, gaskets and oil seals ready to go back in the cases.


I also got some new oil cooler hose and fittings from the extremely helpful Torques, APE heavy duty cylinder studs (shown with an OEM one for comparison) and some new head nuts and washers, since they were about 40p each.

Looking good, keep up the good work...

Any chance you could post up the prices for the engine bearings?

I've got a 1000 that I need to get finished and should really replace all the bearings since I've got the engine in bits...
