Clutch Pilot bushing

Engine is 1.4 turbo

You need a bushing of some sort.....it supports and centers the input shaft.

If there is a bushing in the center of the crankshaft (as opposed to a little roller bearing) just wipe off the inner face and put a light coat of grease in it.....also a light coat of grease on the input shaft nose and splines.
Light means, coat using your finger tip....almost transparent...as opposed to blobs that'll get thrown at the disc, (and create engagement shudder).

If there is a formal roller bearing, remove it, replace with new, and put a fair amount of grease in it if not prepacked with lube.

The input shaft is bigger than the bushing so I’m not sure what this is. It may be a spacer does anyone ever see something like this... I’m worried if the tranny will go in with this bushing....

It is plastic and the GM part is 9157141

Ummmm......you got me on this one......looks more like something used for packaging/protecting.

I think you are going to have to go after a parts diagram or see if a dealer has the bearing/bushing we are discussing for your review.
Throughout this thread I've been hoping a GM wrench (there are several here) would pipe in.......your photo should wake one up (I hope).

Don't let the post die.....report your findings please.

After vast review on the internet and reviewing GM diagrams - I think this is a bushing for the GM Alignment tool that stays in the crankcase hole. So I assume the transmission shaft floats since it is kind of short. The tool that came with the new clutch will not fit in this bushing so I assume I need to modify it to work. The GM tool is over $400 bucks which I'm not going to buy. Hopefully the tranny goes in and not restricted by this bushing.
