clutch problem
Turbo Mini Forums

with the engine not running you can select all gears
with the engine running you can't select any
clutch pedal is dead with either running or not running
seems to me clutch is engaged but clutch arm is in the disengaged position (opened)
any help much appreciated
thanks

Check/replace the fluid and bleed the system?

In the 13's at last!.. Just

Have you forgot to put in the clutch thrust bearing?

Is it a new build or has it been running?

master cylinder goosed

Clamp the flexi hose between the master and the Slave cylinder, if theres a pedal your master is fine and it could be the slave cylinder but id be thinking its the master cylinder seals...

as the lads above said the more info the easier it is to rules things out! best of luck

does the clutch arm move and how much.
is it verto or pre-verto.
have you had it all to bits and only just assembled it.

pre-verto just relaced slave cylinder because while driving noticed clutch slip then one day the piston inside the slave cylinder came out to far and goosed the seal so now i'm at this point replaced slave no air in the system but no clutch

does the clutch pedal stay on the floor when depressed?

is the clutch arm in the 'wok' moving when you depress the clutch pedal?

no and no

no and no
the clutch plunger and arm seem to be in the position when you press down on the clutch pedal

sounds like air in the system, they can be a bitch to blead. they do a braided pipe straight from the top of the master cylinder to the slave cylinder, this way you can hold the slave above the master cyl when bleeding so much easier.

Just a couple of thoughts....
You say PRE-verto, if so, the slave cylinder should have a large circlip in the "open" end to stop the piston coming too far forward but you say it came so far forward as to goose the seal? Was the circlip missing from the old cylinder but there in the new one so the new one won't push out as far as the old one.
And, if the cylinder was/is working right at the far end of its travel and the arm looks as if it is in the disengaged position, it could be the ball end at the bottom is very badly worn (or the clevis pin).

retired that is correct it had a verto slave on a pre-verto clutchreplaced with the correct slave
if you press down on the clutch the opiston in the slave hits the circlip
with the slave removed from clutch housing the arm is still in the disengaged position as if it's jammed
i think i'm going to remove housing to inpsect arm plunger & diaphram

Right, so your new (correct) PRE-Verto slave is hitting the end of its travel (circlip) before the clutch has disengaged and the arm looks like it is in the disengaged position (and possibly jammed there) but the clutch is NOT disengaged.

Try this logic - if it was working OK (slipping slightly but still disengaging OK) on the wrong slave cylinder and the wrong cylinder then goosed its seal because the piston was too far out (the Verto one doesn't have a circlip to stop it) and it has stopped disengaging simply because of fitting the PRE-Verto slave which is limiting the travel, it sounds like your arm was/is operating too far out.

Before pulling the cover, look to see if there is still a gap between the overthrow nuts (the two big ones locked together on the outside end of the plunger) and the cover itself where the plunger goes in. If there is still a reasonable gap (say 2-3mm), the clutch plunger and release bearing are NOT in the disengaged position and the problem could be the arm - bent, or ball end or clevis pin very badly worn. If there is little or no gap, the arm is genuinely in the disengaged position and the problem is most likely a collapsed (or partially collapsed) release bearing so the cover will have to come off...... Enjoy!
