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

I was told by the local pump shop the transfer pump is the only place where you can get diesel to leak into the oil. It's simple to fix. You can unbolt the transfer pump off the injection pump. Take the cover off the pump and remove the snap ring and drive gear and then you can remove the shaft and replace the seal. If there is a deep groove worn in the shaft from the seal you can get that fixed if you take it to a good pump or machine shop. They would rechrome and grind the shaft. It takes CR seal # 4231
