I finally got around to pulling the injector pump out of my old style Ford 4000 4 cylinder diesel tractor. I am getting diesel fuel into my crankcase oil. I understand that this is probably a result of leaking seals on the input shaft to the injector pump. I got two of the main shaft seals and one large O-ring seal.
The pump is a Roosa Master DB04-2933. I thought that I would be able to pull the drive shaft out of the pump by hand and replace the three seals. In fact, the drive shaft does not simply pull out of the pump. Upon further examination of a parts catalog, it looks like there's a shaft retaining ring on the drive shaft inside the pump that needs to come off the shaft to allow it to come out of the pump.
I've looked at a bunch of youtubes on disassembly of the pump, but none of them were step-by-step procedures for removing the drive shaft.
I think I might be in over my head since I'm reluctant to try to remove the distribution head off the pump to get inside of it to remove the retaining ring.
Any advice?
Thanks,
