Oil pump rebuild

Going to install rebuild kit while I am waiting for block and heads to get finished.
Any tricks I should know about?
Took all bolts off the cover, and the cover still doesn't want to come off.
What about the big 7/8 cap on the bottom?
I cracked the alum timing cover on my powerstroke and don't want to make that mistake twice.
Thank you, C

I don't want to say too much without getting my head bitten off here. But you can use a plastic hammer and tap all around it. Don't pry. Just keep tapping and it will come off. The sharp gears will fall out when you do so be careful. Go to Bulltear or theamcforum they have hours and pages and pages of oil pump related stuff.

I think I'll spray sme PB Blaster, then do some tapping on it tomorrow. When I cracked the t cover for the Powerstroke I thought I was goint to faint, got lucky and found a good welding shop who fixed, try pricing one of those covers...could have kissed the guy when he charged me around $75 dollars!

Well these covers are pretty tough. I use a regular hammer to "finesse" mine off. Never had an issue with it. They are not brittle. Don't be afraid to give it a few well placed love taps. And be sure to scrape all the grime off. You might have missed a bolt.

Thank God for cheap fixes. Diesel parts are $$$


I just spend $450 on my new front cover set up. But it's has everything but nickel plating.

Bingo!
PB Blaster, then I cranked on the 7/8 cap and it popped off.
Little gasket had 30 plus years to mate with surfaces
Yes I will clean it thoroughly, with maybe just the slightest bit of sealant when i put it back on.
Any tips on putting cam gear on when installing cam, this is a diifferent setup than the chevys and pontiacs I have built
Thank you, C

An extra arm would help.

The engine being cool helps. Pack the timing cover with petroleum jelly and pop the gears in. Thomas them in with one hand and place the cover with the gasket over it and slide your bolts in.
