I will have to watch this thread. How bad is the oring to replace between the Governor housing and pump? Im going to start there with mine. I havent had a problem with mine for the last 2 years. Run it hard for a few weeks then may sit a month then back on it again on the ranch. This time its sat about 2 months went to check everything the other day and noticed oil way over full and diesel smell to it.
I would assume shutting off the tank valve would help this some? But its not the right fix. I will start with the oring as well. I will try to stay up to date with your findings as well..
Hello DWC7, if your D7E has a cable controlled blade the project is pretty easy as long as you have a decent hoist. If you have the 173 hydraulic control(front mounted pump & tank) it still has to be better than my D7E that has the 172 hydraulic control(fender mounted tank) which has all manner of hydraulic oil pipes in the way!
My bad o-ring problem and the current problem only leaked diesel to the engine oil when the engine was running.

Well I’m in luck mine is a CCU and I have a service truck with crane. Any of you guys have an idea of where I need to look for why mine is draining fuel into the oil while sitting?
My guess is the transfer pump but that should mean the weep hole is stopped up?

You know i just pulled the transfer pump a few months ago due to my filter housing and lines stopping up with rust from fuel tank. My weep hole could very well be the issue? is that the one that goes down into the tube? Its been a few months since i messed with it.
Hi Team,
from memory on these the transfer pump and fuel injection pump housing lifter gallery are teed into the one drain line that mud daubers love to stop up.
I have seen a build up of mud in the belly pans can close the drain lines off too.
The second drain line is from the fuel filter tower bleed screw
Leakage from the transfer pump can either be forced back into the injection pump or if the transfer pump bearings and the packings are worn then fuel can get forced up past the oil sealing packing in the transfer pump seat assembly and into the accessory drive housing.
Cheers,
Eddie B.
I'll check that out.
Thanks Eddie,
Craig
