crankcase full of diesel

[Mark Curtis]

I have a super 55 diesel that has fuel leaking down into the crankcase. Can anyone shed light on this problem. I have already put a diaphram in the fuel supply pump, but it keeps happening. Is there another solution? Ive heard about a little o ring in the injector pump to replace but isn't that a big expensive project?

Well first of all how fast does the pan fill? Does it fill while you are not using the tractor. The little O-ring could be the problem and you can change it yourself in about 15-20 minutes. Find me on the HPOCA site if you want details.

What brand of injection pump does it have? On Roosa Master pumps they have a couple umbrella type shaft seals. It"s easy to roll the fuel seal over sliding the pump on to the shaft. The sleeve the shaft and seal ride in can also wear and cause the shaft seals to leak.

The pump I have is an American Bosch psb4a-70y-3797b1.

I have a Super 55 oliver restored. I take it out on occasions so it isn't running a lot. The level of the oil/fuel mixture is about two 2 inches above the high level mark on the dip-stick. I observed splashes of oil on the frame the last time I had it out and investigated. I was told I needed to replace a seal in the pump. The tractor runs fine. I just need to stop that leak.
