Fuel in oil Case 500 (PSB 6 pump)

[Burl1949]

I'm getting fuel in my oil, and from previous posts suspect the transfer seal may be the culprit. Can anyone suggest a source for this seal? Part# is PK 7910. Hopefully this is an easy fix, other than this issue, the tractor runs great for parades and pulls.
Thanks!

Very simple fix. We stock the seals here, and any Diesel shop should also. Very economical. I'd like to know how many pumps were needlessly removed & hundreds of $$$ spent on this issue.

That's good news, John. If you would send me ordering info, I'd be happy to purchase from you. Shipping would be to 04345. Hopefully this is the problem, and not a leak somewhere in the actual pump. My logic is it leaks while sitting, so most likely earlier rather than later in the fuel flow to the injectors. Might have to use another tractor for the Veterans Day parade this year! Thanks again.

I just replaced one on my 400 this summer, it took about 20 min. and I was done, mine came from John as well. Good luck with yours.

The transfer pump seal leaked on my 500 and I found the shaft worn where the seal lip ran. I couldn't find a new or good used shaft anywhere. I ended up machining the seal seat in about 3/16" so the lip was running at a new and correct diameter shaft. Worked great. PK
