Or sorting out the cause of the problem - rather than a band-aid solution?

Only thing i can think which may, or may not work, is to cross-drill the centre web (on the clutch-side obviously) into the centre-main oil drilling. You could then drill the thrust washer in the 'groove' such that you're making sure lots of oil is getting to the area in question. Would only need a very, very small flow of oil - to supplement what is already there squeezed out of the mains, but it might help...

yes but that is not sorting the problem either.........the problem being the clutch

I had the same idea Ben, although Dave is totally correct in what he says about getting rid of the root cause of the problem, which is the high clamping (and hence dis-engagement) pressures that seem to be required.

However I don't know much about how you would go about reducing the spring force whilst keeping a high torque capacity, and so turned my thoughts to 'fixing' the problem.

My idea was to see if you could increase the thrust area somehow, coupled with a better spec material. Or the other idea I had was to incorporate a pressurised oil feed from the main bearing into the thrust washer. This would neccesitate having a special thrust made up, that had a diametral groove, so that oil was forced through the clearance gap, thus creating an oil film to take the load and stop the thrusts getting chewed up.
The obvious flaw in that plan is that the thrusts are of course 2 piece, and so to get an effective oil film lubrication working, the 2 halfs would have to fit together VERY well....



You mean similar to this, Dave?!

Would some sort of fixed thrust bearing at the other end of the engine, possibly running on the pully counter act take some of the force that the clutch is exerting and keep it off the thrust bearings>?


How about a hydraulic release bearing against the pulley nut (area) Linked to the clutch master.......so when you push the clutch down it also pushes the crank back the other way relieving some if not all(depending on bore sizes)THe plressure on the flywheel side thrust washers*oh well*

Looks like a load of scrap metal to me... I'm surprised the pistons hadn't nipped up in the bores actually.

So how did you let it get this bad?!?!?!?!?!?!?!?!?

holy shit...i'm glad i stopped driving mine as soon as the revs started dropping with clutch in, didnt let it get bad enough to stall the engine.

OKOK, I'll admit it. That thrust-breakdown is far worse than mine...

Now, what do I do to get the reign back????

Is the block scrap as well?

Mine gets in the way a bit, but only when it is up. If it is down it does not cause a problem.
