Clutch Pedal Biting HIGH
Can someone advise how to change the biting position on a clutch pedal.

Mine is very high, when sometimes when you touch the clutch it revs.

The biting point is to high.

As far as I know the you will have to access the pedal box.. In there you will find a threaded rod running through a trunion and there are adjustment nuts either side of the trunion which will adjust pedal height and pedal free movement..
My manual mentions a bolt accesssble on the front face of the pedal box been used to alter pedal height but on mine that is definate ly not the case.. That bolt only limits the downward stroke of the pedal..
There are most probably differences in pedal boxes so you would have to check, or someone may know when the changes took place👍

1. As Andy stated, also check that the master cylinder push rod is ‘free’ when the clutch pedal is released. Thats to ensure that the non return valve is working properly and no residual hydraulic pressure remains in the lines.

2. If it is Td5, check that the fuel pressure regulator is not leaking. That can cause the clutch to slip.

3. Could be a worn out friction plate where it has become too thin - so not enough clamping by the pressure plate. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

As Andy63 mentioned, it’s fairly easy to do, just make sure it’s not loose once you’re finished adjusting.

There is a pedal height specified in the WSM, I expect you may be able to find it on here somewhere if you search for it. $W33T $0U7H3RN $UG4R

Technically it's not a non return valve but just an open path between the reservoir and the slave cylinder through the master cylinder so that the slave cylinder is free moving and resetting for clutch wear.
