Recommended Posts

Just got a fresh engine rebuild!!!... but the clutch wont disengage :(

It's a 1971 2002

has new 228 aluminum flywheel, and clutch assembly.

The clutch pedal has a lot of play in it, it is very soft, and very close to the floor board (as if it is already partially depressed).

My mechanic gave up. I don't know what to do.

Any suggestions?

That ^^^ is the bearing that I have. I still have the 4 spd transmission in.

Thanks for all the advice; I just needed somewhere to start. It wasn't as if my mechanic gave up right away, he tried a lot of things. He said it was probably the pressure plate or the clutch plate. I didn't want to just order a new assembly and have the same problem.

does anyone have the specs on the appropriate width of the clutch plate and flywheel. Maybe they are defective?

Where did the flywheel come from?

Can you get the release fork to hit the clutch 'fingers'?

You'll feel it hit, and hear the 'clink' as they touch.

If the spacing was wrong, the clutch slave should blow up trying

(ask me how I know this) or it's defective.

Or full of air. It's quite possible to get the slave upside- down

or sideways and be un- bleed- able...

It is possible that your clutch/flywheel pack's a different thickness,

but... it'd have to be WAAAYYYY off to not partially work, and you'd have

different symptoms. And you would have noticed it immediately when you

got the parts, as in, 'crap, this thing looks wierd'

Oh, hey- new clutch flex line? A plugged/collapsed one of those will play hell...

First off, thank you to everyone who has helped try to solve this frustrating problem.

Anyway.

The flywheel and clutch components are from Ireland Engineering.

So I just went and pressed the clutch pedal down a bunch of times in the dead of night (so it would be quiet) and I didn't here hear a "clink" sound at all.

Also, I noticed that the CLUTCH pedal starts out a tad bit lower than the BRAKE pedal, and when you press it down it's halted, as if it's hitting something. So there is about a 3 inch gap between the floorboard and clutch pedal when it is fully depressed.

The clutch slave should blow up when trying what?? Sorry..

You think I might need a new clutch flex line?

Also, I should note that the mechanic suspected the clutch wouldn't disengage before he even bolted the tranny up. He said something about the fins were already starting to compress...?

. He said something about the fins were already starting to compress...?

Shit. That means your guy has done fewer clutches than I have.

They (the fingers of the diaphragm spring)

are supposed to move quite a bit as you tighten the

plate against the flywheel. Usually to about vertical, or parallel

to the flywheel surface. That preloads the diaphragm spring, and makes

it clamp.

You'd have to crawl under the car and try moving the arm by

finger power to hear what's going on. Ideally, you'd have

someone else step on the pedal to see if the slave's moving correctly

(about an inch, or a bit less) to rule out a hydraulic problem.

If it is moving correctly then call Ireland- talk to Jeremy, or Jeff - politely!

they'll sort it out if we can't by Monday.

so I bled and bled and bled with no luck. The slave is moving less than an inch and then something halts any further movement. While under the car I was able to see the bearing actually moving against the pressure plate fingers until it stops, and I hear that "clink" sound.

The clutch only moves half way towards the floorboard before it is abruptly halted.

any ideas?
