New Clutch will not engage!

[Seanh]

Well I got my car done and finished up today with the new clutch. I hooked the clutch (slave?) cylinder to the side of the transsmission and all, and bled the system, but I'm still having to pump my clutch pedel to get the clutch to engage. What needs replaced? The master cylinder, or slave? or what is where and what needs reaplaced? Any help would be great, Thanks!

first check to make sure the system is bled properly, also make sure your fork is adjust properly for engagement.

i would chek over the master and the slave. if they need replaced they are both fairtly cheap parts.

look at adjustment on the slave for the fork and see if this does the trick.

that was my problem when i installed the 5 speed into the 71 i had.

In addition to the hydraulic cylinders you might want to examine the clutch pedal arm, where the master cylinder attaches. The hole where the clevis pin connects the pedal to the master cylinder will (over time) get ovalled to the point where a significant amount of pedal motion is taken up just getting the pedal to actually (HA HA) actuate the master cylinder. That was a problem on Bambikiller and I ended up getting my pedal rebushed with a hardened insert so the hole in the pedal arm will stay it's correct 8mm diameter. That made a world of difference and my clutch now works just like it should.

It's easy to check, just "duck" under the dash and operate the pedal by hand while observing the clevis pin. If the hole in the pedal arm is ovalled you'll see that the pedal moves a lot before engaging the master cylinder. If not, you've eliminated one possible cause in a quick two minute check.

FWIW,

I fought a similar demon once.The problem was the fork that rides on the release bearing was not on correctly in its groove.It was kinda half right.The top fork was in,the bottom was behind the groove.The bitch is you have to slide the tranny back to correct it.You can look into the slot where the clutch fork goes in to check this. Have fun!! Daniel

Well, today I checked the pedel and everything seems ok under the dash. I had a friend push the clutch while I watched the slave engage. The slave seems to be engageing correctly, it come out of the bore the same amount of distance every time, but for some reason the clutch behaves strangely. Perhaps the pin comming out of the slave needs adjusted? It is a little bit lose when the clutch is not pushed in...What do you think is wrong now? When I dont pump the clutch, just depress it once and put it into 1st, and start to let out, the clutch hooks up immediatly and the car takes off, so I know something is not right. What do you think now? Thanks

I believe there is more than one type of slave for the early Zs. If they are the same then the fork may be different. I bought one with an adjustable rod and another with no adjusting rod. Unfortunately I don't know which is right. Check the forum for pix and more info with the search function on this site.
