Beau_ Posted October 29, 2014 Report Share Posted October 29, 2014 Hello, I have a 71 240z. Production date is 03/71. I've been have an issue with the clutch not disengaging. I have replace master/slave, all lines, clutch, and p.p. When i inspected the the transmission, I found the throw out bearing was not reaching the pressure. This is manual moving the clutch fork with the slave pushrod disconnected. I have verified that I have a early style three piece transmission and matching throw out bearing. Will moving up to the later style(longer) throw out bearing solve my issues? Thanks in advance, Beau. Quote Link to comment
datzenmike Posted October 29, 2014 Report Share Posted October 29, 2014 The throw out or release bearings are all the same size (generally) It's the bearing collar that holds the bearing that comes in different lengths. The transmission type doesn't matter. The pressure plate and the the release bearing collar should be a matched pair. Now when did this start to happen, as the collar that is on there should be the correct one for your car. So what has changed? recently? Has it ever worked while you have had the car.?

banzai510(hainz) Posted October 29, 2014 Report Share Posted October 29, 2014 you ck the slave cylinder rofd length also. By chance the new one is different. Most time I alwasy used the old one. I got to ck my book at home but I think there was a 1 yr different in the diaphrame height or mike can look that up as the PP plate part numbers were different. Quote Link to comment
Beau_ Posted October 29, 2014 Author Report Share Posted October 29, 2014 Thanks for the replies. The clutch never worked. I'm assuming that was the reason it was parked. It all appears to be original. The collar is the shorter one and the clutch kit I bought was for a 71. I also still have the old p.p. and clutch disc. They didn't have too much wear on them. I'm manually moving the clutch fork by hand to eliminate the hydraulics. I can see that the release bearing isn't not pushing on the fingers, just barely touches it, then the fork bottoms out on the trams case. Quote Link to comment
