Posted July 20, 200420 yr comment_88257 Hey all fellow grateful zed heads, I just put a 78 tranny / 78 slave / 78 clutch pressure plate/disc in my 72....it doesn't have enough travel to engage the clutch..... no adjustment on a 78 slave....so do I adjust at the 72 master cylinder lever that attaches to the pedal? that is all I can think of....the only adjustment available....I have a 78 master cyclinder, but it looks identical to the 72 master clutch cylinder....I'm thinking that the lever connected to the clutch pedal needs the little nut undone and adjusted to full length....I'm only getting about 1.5 in of travel at the slave....fully bled. Help! --Dog Link to comment https://www.classiczcars.com/forums/topic/12585-need-quick-response-going-to-do-this-now/ Share on other sites More sharing options...
July 20, 200420 yr comment_88258 Try a longer rod on the slave cylinder. Just pull the rubber boot off of slave (the rod comes with it), measure rod diameter and length and find some steel to make various lengths till you find one that works (radius the ends on sander/grinder). The adjustable 240 type will also work, but needs the pivot arm with the hole (you probably don't want to drop tranny to change it though).

Help! --Dog Which Throw out (Clutch Release) bearing collar did you use when installing? The 72 collar or the 78 collar? This sounds like what happens when the 72 collar was used, when the 78 collar should have been used? Adjusting the M/C rod at the pedal will have a limited effect since the M/C (and Slave) have a finite amount of travel within the cylinders.

July 20, 200420 yr comment_88319 If you use a 78 clutch and pressure plate you will have to use the throw out bearing carrier from a 78. The 72 is too short. Either get a 78 carrier or put in a 72 clutch and pressure plate.....Lance Link to comment https://www.classiczcars.com/forums/topic/12585-need-quick-response-going-to-do-this-now/#findComment-88319 Share on other sites More sharing options...
July 22, 200420 yr Author comment_88526 thanks for the responses guys....yes, I have a 78 release bearing and collar and fork. Everything other than the flywheel is 78 (and the rest of the car)....anyways, by adjusting the nut on the m/c that attached to the pedal, I was able to get enough actuation of the clutch, and I'm driving now. Thanks. The issue was that I was used to the adjustable slave on my 72 and when the clutch felt like it needed to be adjusted, there isn't any adjustment at the 78 slave. Since the pressure plate is so much narrower on the 78 than the 72 this adjustment was apparently very small, like 1/2 inch.
