Hello all- kinda new posting here but I’ve been reading your material for years. Really good stuff here for sure.
So I’ve got a JD 310c backhoe.
Steering just stopped working after shutting off the machine for lunch.
I first dropped both lines to the steering cylinder. Very little pressure either direction when the machine was running and I turned the steering wheel. I then pulled the supply pressure line to the steering valve- very little pressure and flow. The wheel just spins either direction with no stops. (I thought there should be a stop in either direction.) I pulled the top steel fuel tank cover and got into the priority valve and inlet pressure seems low but I’ve got flow. Same flow or a tad lower coming from the outlet side going to the steering valve. I do not have a pressure gauge yet- need to buy one. I believe it should be like 1000-1500psi. Anyone have a manual to check that spec for me?
I followed the priority valve pressure line right back to the pump off the front of the engine. The pump was replaced about 10 years ago or 1500hrs ago from John Deere. With out pressure gauge, I’m spinning my wheels and can’t see straight. Can someone help me see the forest thru the trees on this one?
Too many parts to take apart - and replace and “Guess.” Makes a costly mistake.
thank you,
Joe
