I am looking for a rear main seal installation tool GM # J39084 (for the 6.5). While I am replacing my flywheel, clutch, and pressureplate I think I should replace it. It is leaking a little not bad but I want the best for the new clutch assy.

I also need a pilot bearing extraction tool. AutoZone will rent me that one for $20. But they don't have the rear seal installation tool.

Where do you rent one time use tools? If I have to I will get a friend to turn up a steel bushing to hammer against and hold it as straight as possible but I don't want to mess it up and would rather use the special tool if it helps.

Looking at the helms manual picture it looks like a cup with screw press mechanism you can bolt it to the crank and press the seal in gently and squarely.

i aways use a small hammer and tap lightly around the outside til it is in flush around the outside with the block

Your Auto Zone rents tools, I thought most auto zones loaned tools with no charges

I think it's a "deposit" system. Tool back, money back.

Here is an old trick for removing pilot bearings that I learned from my dad about 30 years ago and I still use it. Get a bar of soap, shave slivers of the soap with a knife and put the slivers in the pilot bearing bore. Find a piece of steel or brass that is about the same diameter as the pilot bearing. Lightly hammer the soap into the bore with the piece of steel. Add more soap, repeat. This will hydraulicly remove the bearing. Works every time. Clean out soap when you are done.:cool:

You can do the same thing with grease. Just stick the end of your grease gun in there and fill it up. You might have to put more grease in as it comes out.
