Hi ya! Ok...so I reinstalled a pre-verto clutch on a 78 mini...here is the issue...

Adjusted it per http://www.7ent.com/...adjustment.html
The arm did not move much at all with the 7/16 bolt all the way in. Did some more research and seen

http://www.7ent.com/...do-i-check.html

I removed the starter and seen the pressure plate move, but the gearbox is still engaged (tried pushing the car in gear and clutch engages). I was reading about removing some of the inside if the flywheel.

Anyone done this and have any tips? Also, any other solutions?

On a side note, the car does roll fine with pushing and not in gear.

Oh, what I mean by the arm not moving with the 7/16 bolt all the way in...when pulling it by hand...clutch depressed moves the arm moves about 25mm or so.

With the overthrow nut & locknut undone and wound well clear of the clutch cover, and with the clutch arm stop bolt set to a gap of 0.015" to 0.020", during full depression of the clutch pedal the top of the clutch arm must move a minimum of 0.50". If this is not happening there is a problem with either the clutch hydraulics or the clutch pedal mechanism.

Just out of interest which flywheel are you using? I had an ultralight flywheel which didn't have the correct taper which was jamming the primary gear up.

[Jmccrary]

Cooper man....oh I got more the .5" travel :)

Stock flywheel from what I can tell...I am thinking the c-washer is getting jammed...I really do not want to pull the clutch again unless that's the only way....

Check the ball on the bottom of the clutch arm. I had one snap off once and another time one was very worn. Can you confirm that the plunger is moving inwards.
It's unlikely to be the C-washer as once the flywheel is on it can't move really.
It could be the primary gear seized on the crankshaft and if you have fitted new primary gear bushes of the latest type they can seize if there is insufficient running clearance and I had that happen a while back.
The other issue could be excessive crankshaft end float. You might want to measure the end float.

Plunger moves fine and I can see the pressure plate moving.  When I had the flywheel off the other day, the primary gear moved fine with no issues.  Also, it did not move "excessive."  I guess I will have to find some feeler gauges to check the float.  Just did not want to pull the flywheel...again...I am starting to become a professional.  Also, almost close to just changing it from a pre-verto to a verto!!

Ok...what happens if the diaphram is shimmed to much?

[Jmccrary]

Alright....so I removed the clutch, cleaned it all out and checked the gap. It's around .025 - .030. Put it all back together and....nothing...also readjusted the arm again...I'm at a loss....

[Gr4h4m]

You got the straps the right way around

[Jmccrary]

they are flat....but yeah, just as when they came out...gonna take it to a professional if it was slipping it would be easier to figure out, but everything I can see moves how it should, but won't disengage...sometimes you just have to throw the towel in...if someone was close and was able to help me fix it, I can pay with beer :)

Friction plate the right way round & sliding freely on the primary gear?

Balance,"A", marks all matched up?

Release bearing thrust plate the right way round in the pressure plate?

[Jmccrary]

Ethel...the plates don't have the "A" markings, but everything installed according to the book. Although the clutch arm is moving, going to bleed the system again and then do the unthinkable...bring it to a mechanic to look.

[Ethel]

With the engine running, you should be able to hear the release bearing spin when it makes contact. Adjust the return stop out to there, or even a bit further, to ensure the release mechanism has plenty of push. If you find you can cause the revs to drop, by pushing against the thrust bearings, you can be sure it's not the release mechanism that's the problem!

Thanks for the tips...I'll throw the starter in tomorrow and try it out
