My WD45 started to get diesel fuel in the motor oil. It has the American Bosh PSB6A-75Y-4123A pump on it. I can not find any manual for it. I have watched a few videos on similar pumps. But they don’t seem to explain everything. I’m thinking it may be the lift pump on the side of the pump. By the way all of the videos show but they don’t mention all the procedures for getting it off. I’m hoping I can leave the pump on the tractor to repair it so I don’t have to remove my loader to get to it. Anything will help

Definitely the lift pump. Were you the one that posted this question on yesterday's tractors? It's a very common problem on PSB pumps and a very easy fix. See my response there: https://forums.yesterdaystractors.com/threads/die.1698749/

To confirm: You don't have to remove the whole injection pump. You only have to remove the lift pump, which is a very small and easy-to-remove unit on the side of the injection pump. Shouldn't be more than a half hour job at most from start to finish.

Do I need to time anything before I remove it

Nope, no timing necessary: Because it's just the lift pump, it doesn't care about time, nor does it affect the injection pump timing. Unhook the lines from the lift pump. Undo the two bolts holding the lift pump on (centre top & bottom of the lift pump) and the lift pump should slide out from the injection pump. The drive gear will be held on the lift pump shaft with a snap ring. Take the snap ring and drive gear off to expose the seal beneath, pry out the seal (carefully - you don't want to score the shaft or housing. Best to stab directly into the old seal to get a hole to pry from). Lube the new seal up a little with some light oil or thin grease. Press the new seal in evenly (make sure it's the right way around, and that the lip doesn't catch and flip over as it slides over the shaft). Put the gear and snap ring back on. Re-install pump (may have to jiggle/turn it a little as you slide it onto get the gear teeth to mesh).
I can't remember if there's a gasket between the lift pump housing and injection pump. I don't remember one, but if there is you may have to make a new one out of some gasket material (try to get the gasket material about the same thickness as the old gasket - probably pretty thin). But as I say, I don't think there's a gasket in there.
SKF seal #4231 (or equivalent): 7/16" inside diameter, 0.836" outside diameter, 3/16" overall thickness. Edited by DanielW - 19 Jan 2024 at 12:11pm |

Fuel can also get in the oil from the control shaft compartment.Remove the cover below the pump head and check for fuel inside the cover,there should be none.Here's a couple links that will help.http://allis01.com/fossto/56WD45D/ac-wd45d-PSB.html http://allis01.com/
