Leo B Posted May 26 Report Share Posted May 26 (edited) I am asking for your help. I have a 1963 4 Speed. The clutch disengages as it should, but when you start moving, the gear will not engage unless you press the clutch to the very limit. Clutch shakes also a little. I conclude that the clutch comes off at an angle, allowing the gearbox to spin a little along with it. I have restored the pedals, New Clutch Plate, new Pressure Plate and Clutch Cover. The Releash Shaft has been restored and all the bushings and likewise the Suport Brancet. Whole Clutch Pedal Travel is OK. New Pressure Bearing. Fly wheel looks fine (have not measured). The only thing left is Housing, which might have wrong alignment? Could this be the reason? Something else? Edited May 26 by Leo B Link to comment Share on other sites More sharing options...

It is now installed according to the alignment of the dovel pins and all the surfaces are clean, but it may be wrong if Bell Housing has been replaced or installed without checking alignment. I'll tell you how wrong it is (if it is). Link to comment Share on other sites More sharing options...

When replace the pilot bearing, for checking, I could make a test shaft that would be exactly the same size as the shaft of the gear box. Not a difficult thing.👍 Edited May 29 by Leo B Link to comment Share on other sites More sharing options...

Not a difficult thing.👍 Good thought…. and sometimes dried up or gummy old grease at pilot bearing can cause an annoying drag on input even with pedal at full travel.

I would think that when the car is stationary, the engine is running, the gear is on and the clutch is in the bottom, then the tight pivot bearing would wear looser.🤔 Link to comment Share on other sites More sharing options...
Leo B Posted May 30 Author Report Share Posted May 30 I found the problem: Clutch Fingers where in different height. They weren't on the same level. Link to comment Share on other sites More sharing options...
