Posted May 29, 20222 yr comment_640993 New day, new saga. I put in a new flywheel, clutch, pressure plate, and throw out bearing. The master cylinder and slave cylinder are also new. When I put the car into gear, with engine not running, and depress the clutch, I cannot roll the car. Apparently, the clutch is not disengaging. I adjusted the slave cylinder quite a bit also. What am I missing? Attached is a video of the slave cylinder in action.

The Fidanza sticks sometimes. p.s. did you measure the stack height of the flywheel and throwout bearing? 92 mm. A very common error, mismatching the parts.

It is a Fidanza and Southbend clutch. I did attempt to take some measurements, not really knowing what I was measuring. I have a pic, I don't know if it's useful or not. Also this is a 72 240Z.

The Fidanza thread is a few years old. The instructions they now give are to completely remove the green coating, which i did.

May 29, 20222 yr comment_640999 Uh oh. Take that measurement that EuroDat shows. It will tell you if the throwout bearing is close. I have posted an measurement from the bolt head also. Not sure if it's in that thread or not. Yours seems a bit far away. Could be a short TOB sleeve.

May 29, 20222 yr comment_641000 Here it is. About 6 cm from the flat part of the fork to the edge of the bolt head. Link to comment https://www.classiczcars.com/forums/topic/67529-clutch-wont-disengage/#findComment-641000 Share on other sites More sharing options...
May 29, 20222 yr Author comment_641002 Ok, here is my measurement. EuroDat's spec is 115mm. My measurement seems to be 120mm. This somewhat coincides with my stack height of aprox 88mm. I'm about 5mm away from both methods of measurement. The bigger color is 12mm taller I believe. This is frustrating for sure.

On my video, I had the nut adjusted to about 3/4 of the rod length. What do think about my measurements?

It appears I am getting the full range of motion from the slave cylinder, so I think the master cylinder is doing its job. What do you think?
