I finally got that old Detroit 60 series to stop weeping oil

The rear main seal had been seeping for months on a customer's dump truck. After three tries with different installation tools, I got a clean seat with a Lisle alignment sleeve and it's been dry for two weeks now. Anyone have a better trick for those stubborn two-piece seals?

Three tries and it finally held? Man I would've lost my mind after the second one lol. Those two piece seals are the worst, feels like you need a degree in black magic to get them seated right. I've heard of guys freezing them first but never tried it myself.

My uncle swears by the freezer trick for stubborn o-rings. He does it with the rear main on old Ford trucks. Says it gives you an extra thirty seconds of wrestling time before it warms up and expands. Still looks like a fight every single time.
