I know you wouldn't put much as you don't want it on clutch face, but I was thinking I'd read that you would put a bit of lube on the front splined shaft for the throwout bearing to ride back and forth on.

-Do you lube that shaft?

-If YES, what type of grease would you put on it?

Thanks,

I would use Never Seize. I am sure others will chime in.

UM ,your throwout bearing ride's on the splined input shaft?

D,
Throwout bearings ride on the front bearing retainer (that's the part that the input shaft goes through) of the tranny. The input splines only go into the splined center of the clutch disc. You don't want lube on the splines, because it can sling off and get between the clutch disc and flywheel and pressure plate. Throwout bearings have a groove inside the bearing. Fill this groove with a good grease (chassis lube is fine). This will allow the throwout bearing to move back and forth on the front bearing retainer of the tranny.
If you use a pilot bearing in the crankshaft, grease the rollers thoroughly. If you use a pilot bushing, there is debate about whether or not to grease the hole in the bushing. I always grease a pilot bushing thoroughly.

"Throwout bearings ride on the front bearing retainer (that's the part that the input shaft goes through) of the tranny."

Yeah, that's what I meant to say.... (oooops!)

Would you use a chassis grease on the pilot bushing?

Thanks for the responses!

Yep.

crap i just lubed my splines

Generally speaking you don't lube the splines because they are intended to run dry. Tom is correct in that there is a chance that the grease would migrate to other clutch parts with undesirable consequenses. More importantly you don't want to grease the splines because dirt and clutch debris will saturate the grease on the splines and eventually interfere with the clutch operation.

Same reasoning behind not lubricating your throttle linkage. You want stuff like that to "self clean" through its normal operation, shedding debris rather than retaining it.

I've used dry graphite on the splines.

The debate about the bushing keeps on going. I don't use any lube, the bushing itself is the lube. I don't think it hurts, but if it ain't broke don't fix it:thumbsup::thumbsup::thumbsup:

im pulling my tranny to clean off the splines now! actually i have another reason but i'd like you guys to think im really that dedicated

Do the splines eventually wear where the clutch splines contact them? It seems like they would get annular grooves around them. I was going to put a 1 molecule thick coating of anti-sieze on my splines, but then didn't. But ya know, this car will probably only get driven only 5000 more miles in my lifetime.

The AC DElco clutch kit I got from GU had an instruction sheet inside that recommended using the small vial of grease they supplied on the splines.

If I remember right Centerforce instructions said to use a dry graphite on splines and grease on bearing retainer for TB
