Clutch lever arm - which hole

#1 Post by Phil T » Tue Oct 02, 2018 6:15 pm

I have just had to replace the clutch hydraulics, but on reassembly I had a dilemma over which hole in the lever arm to attach the slave pushrod.

Any advice?

(I used the one at the shortest distance from the pivot.)

Irrespective of which model, I always have fitted the clevis pin to the middle hole. This gives a pedal with moderate pressure which I prefer - the front hole gives a heavier pedal, and some say gives more clutch cover clearance, whilst in the rearmost hole, there may not be sufficient clutch clearance and some have said you run more of a risk of the seals popping out of the cylinder.
If your clutch is in a good state of health, and the bite was correct for you I would leave it where it was originally.
There were two slave cylinder dimensions 7/8" and 1" bore - some fit a 7/8" slave cylinder to a 2.5 to give more clearance, or fit an adjustable operating rod, but in my opinion, this is only masking a another problem.
I have always fitted the correct slave cylinder for the model, and fitted the clevis pin to the centre hole with no problems. But then again, I always use a Laycock cover with a B&B plate which is supposedly the best combination of bite, disengagement and lightness of pedal, compared with using a B&B or aftermarket cover.
It's also worth checking for any wear on the clevis pin or the fork ends which can affect the operation and disengagement issues.

Thanks for the reply.

I have used the shorter hole to maximise the clearance (simple trigonometry!) as the longest hole was giving a slight lack of clearance for reverse.

(Used the correct 7/8 cylinder!)
