1979 JD 410 hydro trouble

mardi 25 octobre 2016

Hey everyone, long time lurker...first time poster. I've been able to get by up until now based on all of you guys wealth of knowledge, but I need an opinion here.

I have a 79 410D with about 5400 hours on it. Last week, I noticed that the loader would start shuddering a little when I raised it off the ground with or without a load. At the same time, it would almost feel like it was choking out the engine a little bit. I also noticed a knock near the front pump coupler almost in cycle with the engine. Steering is working, but a bit jerky.

Am I on my way to a new front pump here, or is there something else I should be looking for? I know just enough about hydro systems to be dangerous, so I don't want to go stick a pump in this thing if it doesn't need it. Thanks!
