I have been using a combination of installuniversity's clutch install and some GM service info. Installuniversity says to put white lithium grease in a couple of spots noted in the picture.


I used a pilot bushing with my LS7 install. Do I need to put additional lube in the bushing itself or just a small amount on the input shaft of the tranny?

pilot bearing should be pre greased already ,if not put a little dab in it

If he is using the bushing, it will not have any grease on it, coming out of the package. I put just a little on the input shaft to make insertion easier.

why in God's name would you use a bushing instead of a bearing ?

a solid bushing im being told is better then the bearing

bullshit, a bearing will handle loading better and last longer

Hmm, maybe you can checkout this thread and there can be a civil debate on the properties of each. I don't care who's right, I just want enough info to make an educated decision

bushing = relies on inherent properties of the metal for lubrication
softer metal than the input shaft for obvious reasons
contamination will have a more dramatic, profound effect
more prone to vibration or driveline runout damage



bearing = has rollers , no lube needed (or no more than what is provided internally)
hardened rollers for anti wear capabilites
more forgiving against contamination, but not impervious
more tolerant of vib/runout damage

bearing wins........those are my thoughts, any arguments are welcome

If you had to use a bushing ... a bushing made of brass but coated with nickle would be stronger than a regular bushing. It would be more resistance to wallowing out and surface wear. Does anyone make one like that?

cant use that type setup, bronze is used as bushing material because it is a "wet" metal. meaning it has some self lubricating properties...you coat it with nickel and it will ruin the input shaft

Well, I'm using a bushing too. I haven't been able to get a bearing that will stay in one piece with some power behind it. It starts to get old, replaceing the tranny input shaft and what ever other gears that frag, when the bearing decides to seperate into pieces. I haven't had that problem with the bushing yet. I do replace my bushing everytime I change out a clutch and the last one of three years, looks very good.

I can say that there was nothing left of my bearing but the outer shell. That prompted me to ask around. After talking to my tranny guy and seeing some similar things on here, I decided to go that route,

We shall see. I am not about to go rip it out now....
