clutch specs

Can anyone advise...have just removed engine from a 1970 bug...clutch is interesting in that there does not appear to have a bearing plate that the 3 fingers of the (original?) clutch normally attach to (big washer on triangular plate that normally makes contact with the throwout bearing). curious as my other 1970 bug does have such a plate and the fingers of the clutch are slotted to accept lugs underneath the plate). The fingers on this clutch do not have slots and the springs are one piece rather than in two parts . Any ideas about the adjustment of this clucth? My manual says 1.06 inches from flywheel face to the front of the clutch, but having installed a new clutch plate Im having a hard time getting this distance. Any ideas.

Whether or not the pressure plate has the pad on it depends on the gear box used. The early pressure plate (with the pad) is used on early style boxes, which do not have the guide sleeve around the input shaft that the throwout bearing slides on. The early bearing is held with a clip on either side.
The late box has the guide for the throwout bearing and does not have the pad on the plate. The bearing, which has spring loaded clips as part of the bearing unit, contacts with the fingers of the pressure plate.
I back the adjustment off on the clutch cable before installing the engine, and then once its bolted up, adjust the cable up until the pedal has an inch or so of freeplay.
You must put the correct pressure plate for the gearbox/throwout bearing setup.

Also there is a 6mm height difference in the early to late styles.(of the bearing contact surface).
So make sure yours match.

Many thanks for the info. Thats a really big help. Do you happen to know the direction of the hight difference..assume it would be 6mm less for the later style without the plate?

Yes that is correct.

Bergs instructions advise the cone height to be set at :

29 to 30mm for early clutches,

and

23 to 24mm for late clutches.

This is the measurement from the throw-out surface on the pressure plate,
to the ring gear face on the flywheel.

Brilliant! much appreciate the info. :beer:beer
