Removed my transmission yesterday and got some pictures today of my clutch that,"felt like it's binding up or the TO bearing isn't working properly"I forgot to mention earlier.... this clutch is soooo heavy to engage... that's what started scaring my tuner

Pictures of my flywheelPicture of the bellhousingSide picture of the TO bearingClose up Front of the TO bearingTO bearing mounted on spline Pressure plateThis is how the clutch looked when it came outClutch w/o pressure plateclutch Is this normal to have that ring around the outside of the clutch? I looked in the bellhousing to see if it was rubbing on anything and there were no signs of wear.... but paint has been rubbed off but the metal hasn't been gouged...If someone spots something wrong with my clutch please let me know.... I'd hate to have to order a whole new one but if that's what it takes then so be it.

looks like the input shaft is half rounded off?possibly bent shift fork caused it..that would cause binding but thats just speculation...

everything is dry

theres no grease on the TOB or where it sits on the input shaft.

anytime you do a clutch the nose of the input shaft (where it sits in the input shaft bearing, the far end of the nose) should be greased along with where the TOB sildes on the input shaft, also the pivot points of the fork.

not saying thats what caused your problem, but thats the first thing i noticed.oh yeathats a clutch disc

thats a pressure plate

just for future refrence.

Are you talking about the worn paint ring around the pressure plate? If so... it wasn't about to come off... There weren't any loose bolts when I removed the clutch

Lubed the shaft with some lithium grease and replace that disc with a sprung hub type.

Man I dunno how anyone can make any speculations off these tiny pictures. Anyways please describe your problem or symptoms in greater detail. What kind of Clutch? How many miles? Any kind of noise when the clutch is engaged/disengaged? Does it engage? Is it slipping? Does the TO Bearing spin smoothly? How is the Clutch fork? How is the Pivot Ball? etc etc etc.. This will help us get a better picture of what going on

I have all the stock parts from a 25 trans with low miles. I replaced mine with os giken parts to match my clutch. I have stock pitot, fork, to bearing, and I upgraded to a adjustable rod coming out of my slave so I have that too. I still have to get a nismo slave and a braided line. If you want to try some better looking parts I can sell you all of these for cheap. My email is [email protected]

Sorry I haven't been on to update you guys with any info... but between working and reinstalling the clutch/transmission I haven't had time to visit nico...Soooo... Everything was dry as a 70 year old woman, as J.P. would put it... I greased the input shaft, TO bearing, fork fingers and pivot, and pilot bearing.... Got the transmission remounted tonight but i haven't hooked the clutch slave back up.... that's first thing tomorrow and we'll see how she feels....

The clutch is an ACT 6puck with 2000 miles on it.... I just put a new TO bearing on it since we've taken it off.... I didn't think anything was wrong with the clutch at all originally... it engaged and disengaged fine.... never ground a gear... never slipped (that i could tell).... It was just incredibly heavy to push down... didn't engage until almost to the floor and before it would reach engagement it would make a high pitched squeeling noise

I have the same clutch, but since having an ACT clutch in my Maxima, it isn't too stiff for me. But it is very stiff and the engagement is fairly close to the floor. However i don't get that squeal.

Well when we got the bellhousing off and set it down on the floor... the TO bearing wasn't attached to the fork with the clip that fits in the grove... We just pulled the TO bearing right off of the input shaft

So that's the problem right there.. the TB wasn't attached at all to the fork?

I hope so... I went over the clutch with my dad and everything seemed to be in working order... just dry. Now I've got everything greased... the TO bearing is mounted and sliding good on the input shaft... tomorrow we'll find out if that's all that was wrong when i get the slave bolted up. ... Now if i can only figure out WHAT THE HELL is wrong with my PFC....

Any update on how the clutch feels now? Was the TOB just off of the fork? I still don't understand how all that paint rubbed off of the pressure plate housing. Or was that just clutch dust?
