Screw it! I'm getting Wilwood clutch MC.

My friend is having a similar problem.

RB25 into and RB20 tranny....into a Datsun 260Z.

For months and months car was fine.

Then, all of a sudden, problems getting the car into gear....got worse and worse....to the point where he couldn't get it into gear at all.


We dropped the tranny, put in a new PP and clutch (ACT HD and 6-puck).

Still same problem.

I am not there with him, but he says the slave is moving a solid 1/2 to 1 inch, which should be enough I think.

We are completely dumbfounded....about to try the whole "slam it into gear" thing that has worked for a few other people in similar situations.

I researched an article that it requires the slave to have a stroke of 15/16" minimum to disengage the clutch, so I don't think 1/2" would be enough.

From here, assuming the condition of the clutch system is good, I could narrow down couple possible remedies.
1. The hydraulic had leaks somewhere. Take this one out if the clutch MC remained full all the time.
2. The pedal bracket is bent somewhere.
3. The TOB is bad (making noise) or using a wrong TOB sleeve bearing. (I broke my TOB sleeve bearing before when I remove my TOB, and I recieved a different sleeve bearing from ray @ thenismoshop claiming should work the same. It looks a bit different, but there is a chance that the TOB is pushed too much into the sleeve bearing and shorten the overall length... possible?)

the distance between the clutch and pp when disenaged is only ~10mm, so I think even minor changes could be enough to cause problems in disenagement.

When you guys dropped the tranny, did you notice if the flywheel was wrapped with the clutch disc? Did you check the TOB, the sleeve bearing, the pivot ball and the fork?
