Oil loss on D4H

[dozer12216]

Trans fluid goes down to add mark in about 5 hours. I retorqued bolts on rear housing and that seems to dry up that leak.
Hydraulic fluid will drop beyond sight glass in a hour or so. Blade tilt cylinders leak at packing. They might leak a cup of fluid in 5 hours . Not nearly as much as is lost into engine.

Actually the power train pump is a 3 section pump .

Bob's correct. I looked at it and saw it was more then one section and assumed it was two, one for supply, the other for scavenge - just goes to show that you should never assume. The third section of the pump feeds the steering clutches and brakes.

If you have a sample of engine oil analyzed it will test for water, glycol, & fuel among others. All of those should be eliminated as possible causes for a rise in engine oil level.
