Pilot bearing removel?

**kingls1** · 02-17-2013, 10:46 AM

Getting ready in a few weeks to put in a new Ls7 clutch and have been doing some reading on install and gathering parts and tools.
Any help on the best way to remove the pilot bearing, was reading over on Tech and some Vette forms that a Blind Hole Puller set is the best tool to remove the bearing
Anyone have any info or tools used?

No interest in using grease, bread, or paper smashed in to force it out, sounds like trouble to me.....

One more thing to add to this question, may sound dumb but about how much clutch fluid is needed when changing fluid?
I have the factory service manual and it tells the capacities of almost everything but only list's DOT3 fluid. Fluid I'm using comes in a12oz bottle...searched all over still nothing!

I have had success using seal pullers on pilot bearings.

Not sure on your question about "how much", but here are some helpful threads:

Looking for the capacities of the clutch system(amount of fluid) it would take to flush system.
Comes in 12oz. Bottle do I need one, two or ten?
Trans. Holds 4quarts, rear 3.6 pints, motor 5quarts, nothing listed for clutch system!
Thanks for the links

As I mentioned, not sure on your question of how much

**redbird555** · 02-18-2013, 02:45 PM

I'm not dsure exactly how much but I can tell you, it holds less than that small bottle of fluid so not much. however you will waste a lot of it bleeding. I just bought the larger container and had a little left over after bleeding, even with starting over couple times

**35th-ANV-SS** · 02-18-2013, 04:03 PM

If you want to measure how much you use, I'll add it to my sticky as a guesstimate.

Thanks for the info, what fluid do you recommend ( Brand) is the best for our systems? I was going to use Amsoil but my parts guy don't stock Dot3 brake fluid.

I will do that and let you know Jon

My pilot bearing was a "worse case scenario." I broke the teeth off the puller that I had rented.

I ended up using a Dremel with a Tungsten Carbide bit (bit 9901) to grind out two spots at 9 o'clock and 3 o'clock and it popped right out. I didn't have to cut it all the way through- just cut it most of the way through and then when I hit it with a new puller I was able to split it in half. Takes a steady hand and some patience.

Hope I don't run in to that! With winter hanging on so long up here and now the painter on my new hood taking his sweet time I'm still waiting to tear into the clutch. Hopefully soon, thanks for the input, don't want to use it but if need be I will have the upper hand

Your best bet is to be prepared for anything- best or worse case. Have your puller ready but go ahead and have the dremel out on the work bench. Be careful and don't push the puller too far into the hole- there is a freeze plug behind it that can be pushed in too far. Go ahead and get a rear main seal set and swap it out while you've got it apart. Those are the best bits of advice I can give you having put the LS7 clutch in my 'Hawk back in 2010. The only real difficulty was the pilot bearing, other than that it all went in easily.
