Main Seal Leak M1009

[tom lovinggood]

Has anyone had their main engine seal leak? I have apparently developed a leak in my M1009? Thanks in advance.

Mine did 3 years ago. Truck had 17000 miles on it from the military. It went from zero drip to puddle in the driveway overnight. Jack up the frame to let the front axle droop, pull the pan and get R done. Mine was factory sealed with rtv and was GLUED to the block. I had to use a propane torch around the perimeter to get it loosened with a putty knife.


I reccomend a proper felpro gasket and some light rtv on reinstall.

Gunny--do you happen to remember the manufacturer of the seal, or, perhaps the P/N?¡

It was a Felpro 2 piece rear main seal. I picked it up at the local Oreillys. Dont remember the part number.

BS40529 is the part number I'm finding.
