Re: Rear Main Seal Replacement

Another rear seal remover-installer tool I remember from "back-in-the-day" is with a modified a cotter pin (split pin). Basically, take a proper sized cotter pin and make it look like a "T".

The vertical shank of the "T" fits into the drilled oiling hole in the rear main journal. The horizontal bars of the "T" fit up to the top part of the seal. The mechanic then rotates the crankshaft and the "T" shaped cotter pin catches the end of the seal and rotates it out. Reverse the procedure to install. The dimensions of the "T" are dictated by the size of the oil hole and width of the seal groove.

Like I said, this is from memory and I might have missed something important, but this is how I remember it. My computer graphics skills are narrow and shallow or else I would have provided an image. Comments anyone?

My disclaimer is I cannot recall actually doing this job, but the older I get the more I remember the things I did not do. Did I or didn't I?

Of course this method, like the "Sneaky Pete" way, is done after loosening all the main bearing caps. Probably someone here should post something about that or make a referral to the FAQ, if covered there.

I think Keith's suggestion about the rear main cap drain is something that should be looked at first. And, as long as you are there, how about that oil pump?
