Early 450 dozer rear main seal

Post by mholleywould » Wed Sep 05, 2018 12:43 pm

I picked up a 4039df to put In my early straight 450
It was in a compressor which runs well
So I’m needing a rear main seal and also I think I read where there’s an o-ring between the rear plate and block so I’ll need that also.

My Dad (84) pulled the motor from my 450 last year and I’m not sure exactly what I’m looking at to replace.
I’m familiar with the runner sleeve but all I see is a spring washer, o-ring and looks like a o-ring housing.
Tell me what I need and where I can get one please and a pic would be awesome.

Did you get your dozer running? I am looking for a 450 parts machine.
