Re: Ford 3000, Injection Pump
The Simms pump has an oil reservoir that is used to lubricate the pump. Some folks don't realize that and never change the oil and it gets contaminated with fuel and the pump does not receive the proper lubrication, and then things begin to go south. The oil in the pump should be changed every time that you change the oil in the engine, and using the same oil that you put in the crankcase.
A full rebuild of the pump requires specialized tools to test the pressures at various points and to set the timing, as well as specialized knowledge. If you are merely replacing some of the seals that can be accessed without complete disassembly of the pump, then you could probably do it yourself, but anything more and I would recommend taking the pump to a diesel pump specialist. Make sure that you follow the instructions in the service manual when you remove the pump so that things will be timed properly when you go to re-install it. And make sure that you don't turn the engine at all while the pump is not installed.
