Delphi governor doesn't govern

I'd like to ask a question about the diesel motor for our generator. Our generator has a Delphi injection pump/governor. The regulation of the speed is not great. It's 62Hz with no load on the generator, and as low as 59Hz with load. When there's a heavy load sometimes the generator slows down enough that it trips it's under speed alarm. I tried to increase the speed by turning the adjustment on the injection pump, but what happens is if I turn it to slow the engine down I can, I went down to 58Hz, then as I go the other way to speed up it gets to 59Hz and there's a lot more travel to the adjustment but it has no effect.

Any ideas? From all the techs I've talked to the injection pump/governor is not field serviceable. Does it sound like this one needs replacing already? It's only a few years old and sees about 10 hours of use a day.

Thanks!
Greg
