3910 injection pump

[NHbalerman]

I just bought a 3910 that has been
setting up for a while and the injection
pump is leaking fuel into the engine oil
has to be that seal in the front. Is that a
easy job or does the pump have to be tore
down to get to it the tractor cranks and
runs good no need to be overhauled just the
seal replaced. Thanks

Easy. Drop your coolant. Pull your radiator hose off the lower radiator port. Remove timing gear plate. Remove 3 bolts in drive gear. Mark pump timing location. Remove pump. Replace seal. Reverse.

So the seal is easy to replace I didn't
know if the pump had to be taken apart

There's not much to the seal. You can R&R it without disassembling the pump.

many times but never replaced that seal
