clutch biting point

[dede911]

Hi all,

I have adjusted the clutch (915 box) according to Waynes 101...procedure, but to my personal feeling, the biting point is on the higher side. Switching between daily drivers and P car always takes some time to adapt, also stop and go trafic on slopes ...

If I want to get the biting point lower, is it correct to "pretension' the cable more, so that the 1mm gap decreases?

Thanks,

André

I think that would make it higher. You could loosen it but then it may not disengage the clutch and cause grinding.

You can play with the adjustment - it's quite easy. To determine if it's releasing all the way is easy too. Simply put the clutch pedal down to the floor, and then wait 10 seconds. Then take the shifter and put it in reverse. If reverse grinds, it's not releasing all the way, and you have a problem. If it's difficut to get into reverse, *or* you hear no grinding then, you're good.

You can also adjust the pedal end a little bit (on some of the years).

I cannot remember, if you have everything out, go in small increments and test the result, never forgetting your starting point.

many thanks for the replies.

Wayne,

If I play with the adjustments, how important is the 25mm between pedal and pedal stop?

Even now, with the pedal biting point high, it was difficult to adjust the pedal stop to get the 25 mm

Thx,

André

I don't think you adjust the stop to get 25 mm.

You adjust at the trans. clutch pedal arm - and if needed at the turnbuckle on the cable end near the pedal - to get the spec.

You then set the pedal stop on the floorboard based on the "grunch" from trying to go into Reverse, with the motor warmed up & at idle.


Let em see if I recall this correctly:
If there is too little free play in the pedal -- then you cannot shift in certain gears correctly - exactly which gear may vary (usually 1st) BUT the clutch can work ok when cold, then get worse as everything warms up (making it seem like 2nd or 3rd are worst). At least I think that is was happened to me once.


If there is too much free play -- then the needle bearing for the shaft and/or the throw out bearing may spin all the time (and quickly wear out).

Somebody correct that if wrong.


You need to post the year car you have - not all 915 are the same.

The car is a 82 SC euro spec
