Hey guys, I've just put all the running gear in my hatch and hooked up the clutch but there seems to be about 1 1/2 inches of slack before you feel any presure when you push the clutch pedal in. I wound the nuts on the cantilever set up all the way to the end and its much better than it was when I first put it in but still has that 1 1/2 inches of slack, my mate reckons to just stick some washers or a spacer in it ( see pic ) do you guys think some thing is bent or is there some thing I havent done, it is an original V8 pedal ( not UC ) Any help would be great, heres a pic

CT22 is the stock thrust bearing no.

Just last week i looked at a similar problem for a customers new combo in a hatch, the problem was the pressure plate was icorectly manufactured & the diaphram was passing over centre when it was bolted up.

Hopefully its just your thrust bearing.

the first thing you should look at is the position of the fork, make sure its horizontal to the engine,meaning not pointed towards or away from your pressure plate.If fork is positioned towards P/P, this usually results in the bearing constantly running on diaphram causing a failure within weeks. If its positioned away from P/P, then you require to adjust your rods to maximum. and in most cases there isnt enough adjustment. Check to see if your fork ball has an adjustment,(most later models do) and certainly put washers near your bracket to remove slackness.
A CT22 (gsb222) is only correct for a low profile diaphram.

Might sound stupid but is the folk bent?
Sometimes heavy duty clutches bend the folk but it is more common in the later HZ/commy set up.

I have a similar arrangement in my LH but the pedal is close to the floor and doesnt disengage properly, should I wind the nut to the end of the shaft to push the bearing against the diaphragm fingers? It is supposed to be a heavy duty clutch plate.

I thought it was normal for clutch pedals to have some travel in them before it starts to disengage. Its not meant to be like the brake pedal.

^ AFAIK there should be a 1mm gap between the bearing and the pressure plate.

Shit, how blind am I, look again at the picture!! your nut is in the wrong place!!!!! both nuts go on the one side, you don't require a nut on the end, The big nut should be rounded off to fit in the fork, like a ball.

In the photo, I noticed you had the gearbox attached and the shifter fitted. Did you put it back in this way and how difficult was it. It would make it a lot easier to put these things back together out of the car. :tease:

Thanks, Dan

It can be done with it still attached, but we took it off so there was less chance of scratching the new paint. Its not to hard to put back in once it in the car but the reverse lever can be a bit tricky. Do this before bolting the cross member in, I learnt the hard way

cheers, Dan

Bloody good spotting RED !!!

Myself, like you & probably others went for a more technical answer first, before looking at the obvious simple in your face things.

Proves the "KISS" theory always applies.
