Rear main bearing tool - Blazer Forum

Duckboat · #1 06-12-2009, 03:44 PM

Does anyone have for rent, loan or sale the rear main bearing tool for the one piece rear main bearing engine seal on a 1998 Blazer 4.3 ? I would need tool Kent-Moore J-35621-B Rear Crankshaft Seal Installer for GM or some equivalent to this tool or maybe some other trick someone has for replacing this seal.
Thanks

can you screw a self tapping sheet metal screw into the thin metal face of the seal? thats how i do it on diesel engines and gas engines i rebuild all the time, just use a small slide hammer with the vise grip attachment on it and clamp the vise grips on the screw and give it a slap and presto!!buuuutt sometimes your screw will pull out and you may have to try it a couple of times, if you dont have a slide hammer you can try to install the screw like i said before in the seal face and use an indexible prybar, claw, anything that will work on the screw head, hope this gets you were you need to be!!!

That sounds like a good Idea for seal removal but I am concerned about proper installation of new seal.

I have always tapped new seals in with a plastic faced hammer and never had issues. Have done this on quite a few one-piece rear main seals on GM v8s without issue.

My plastic snap on hammer works for me everytime.
