Very heavy clutch

[Chris Edgar]

1962 948cc
A little over a year ago I fitted a complete new (B & B) clutch, & thrust bearing, as the one on the car, recently bought, was slipping.
It was immediately apparent that the pedal required considerable effort i.e. the clutch springs were VERY strong.

The result of this ( & I do not sit with the pedal depressed unnecessarily ) is that now it is obvious that the thrust bearing is prematurely wearing & getting close to the point where it needs to be replaced....the adjustment has all but run out now.
All a bit of a nuisance.

Wonder if anyone else has expeienced what seem to be clutch springs which are far too strong?

I had a similar problem. Changed the fork, bearing and pressure plate but the engine is still out so I don't know if it's a fix!

Thanks, I have read the threads....maybe I was supplied with the wrong thrust bearing for the 948, seems unlikely however.

For a while I have been planning to exchange the gearbox (which leaks oil a lot & has started "knocking" in first) for a second hand, allegedly good one, I have in stock.

I have ordered a thrust bearing this morning, which I will fit to the replacement box first.

Can't really do the job before week after next, hope that all holds out 'till then. Since adjusting the pedal travel yesterday, it is even heavier than before!

Sorry just a thought.
The clutch pedal hinges on a shaft which passes though the chassis leg in two brass bushes. Are these free?

Is the clutch pedal shaft seized in the chassis leg? That would give a stiff clutch and it would also wear the thrust release out too because the clutch mechanism isnt being released properly.

If you disconnect the clutch linkage is the clutch pedal nice and free to move?

Ive experienced it happen before, the brake pedal sometimes seizes to the shaft too, so you can sometimes apply the brakes at the same time you press the clutch down..

Cheers

Thanks for that Steve, I think its ok, but I will give it a good coat of looking at when I change the gearbox.

If you are having the clutch out check that you were supplied the correct one. I'm sure I read on here that the Midget clutch fits but has stronger springs.

There are only 2 types of thrust bearing (918, 803, 948) and 1098. The pivots are further back on the 1098
