I mentioned in a previous post that I have problems with the gearbox/clutch. At the time I was working on the water pump and cooling, so put the gearbox issue out of my mind. Sadly however I now have to turn my attention to it and would appreciate your advice. Here goes:
- '77 2l FHC, 4 speed
- engine rebuilt (new crank, bearings, thrust washers etc)
- zero miles since rebuild
- engine runs fine
- new 3 piece clutch kit fitted from reputable '7 supplier
The problem: When the clutch is depressed with the engine running, something makes a hideous metal-on-metal screeching sound. It gets worse, and louder, the more the pedal is pressed. The engine revs drop the more the pedal is pressed, to the point that it would stall if pressed all the way. Naturally since the first time I discovered this, I haven't been doing a lot of it!
In my novice-like opinion I suspect one of these possibilities:
- excessive crank end-float
- faulty clutch release bearing (or slipper pads somehow dislodged?)
One other thing worth mentioning is that I changed the gearbox mount for the Volvo Febi type, and had been a bit concerned about getting the height correct using shims. It always bothered me that this was a bit hit & miss. Could the mounting being incorrectly shimmed cause this problem (not sure it would, but thought I'd ask anyway)?
Any thoughts/comments/shared experiences much appreciated.
