Currently my motor is out to replace all my seepy oil seals. My mechanic observed that the seal on the injector pump is also weeping diesel into the area where the belts run. Anyone ever done this? It was not immediately apparent to the mechanic what was required to remove and replace the seal. Is pump dissasembly required? Also, anyone know of an service manual I can download for this pump? Any help greatly appreciated.

Thank you.

This is not something for the do it yourselfer. I have done MANY of these motors personally. Once the shaft seal on the IP starts leaking, it is beyond just a seal. If you try to wiggle the shaft you will notice it wiggles ever so slightly. If it wiggles you won't accomplish anything buy replacing the seal. The pump needs to be completly disassembled by a diesel injection shop and a new bushing fitted into the housing. This a very common wear item on these pump. Be prepared to spend about $450 to have a injection pump overhauled. It's well worth it. That cost of coarse is with you bringing your pump to the shop removed already. These pumps are extremely delicate internally and should be left to a professional. I won't even do it myself with all the knowledge I have.

Just got mine done by a mechanic, ran about $400. Used to have major startup issues, now not. It was a necessary fix.
