ok so you may or may not now i finished my tii conversion a few days ago and i decided to leave the os giken clutch/flywheel on that came with the engine from japan land. So here is the problem. The clutch/flywheel is barly streetable but im getting used to it. Every once and a while if im trying to park and im just riding the clutch in and out and dont let off for a while the pedal will stick to the floor. I have to put it in nuetral and pump the pedal a couple times then the clutch seems to grab a little higher than before. when i get back in later it grabs fine and dandy. one other thing my T/O bearing is pretty noisey but i dont think that could cause these syptoms. any opinions?

 

If the pedal falls effortlessly to the floor the system might just need to be bled. If you have to pump the pedal to get into gear after its been bled properly then you could have a master/slave cylinder problem. The bearing will just make noise, until it gets so bad that it siezes up or explodes.

 

Had the same problem about 2 weeks ago. Replaced the Master Cylinder and everything works great now...

 

oh no.... Thats not good.

 

does anyone know if i need a special T/O bearing for my clutch set-up? I cant seem to find anyone that deals with os clutches.

Dont know if you need a different bearing on the 7's but with a nissan configuration the os giken pressure plate has a smaller opening on the diaphram springs so a smaller release bearing is used. I would call a rotary shop to get a for sure answer.

 

go buy a mazdaspeed or OS throwout bearing. i had a problem engaging 2nd.. no problems with the mazdaspeed bearing.

the ms TO bearing is freakin BEEFY.
