    310 Backhoe Hydraulics

    Update: The pump is back together and is working good. I'm still chasing the slow movement problem when making multiple moves though. I've checked the relief valve, readjusted the clutch (only off a half turn). Yesterday I removed the return line from the backhoe control valve bank (per the...

    Hydraulic Pump Quad Ring

    Thanks again for all you help. It's much appreciated! I have the non-serialized pump. No numbers any where on the pump and no tags. And after reviewing jdparts, the shafts I have (the old one and the new one) are most certainly for the non-SN pump. So it appears I have ordered and recieved all...

    Hydraulic Pump Quad Ring

    I'm not sure which pump I have. How do I indentify serialized or non-serialized? I couldn't find any numbers or tags on the housing. The JDparts website says it is an AR101807 pump so that is what I ordered parts for. The R34348 shaft is what I ordered and is identical to the old shaft as far...

    Hydraulic Pump Quad Ring

    I'm away from the shop this weekend so I won't be able to measure my seal to see what I have for a few days, but I'm guessing the 1.421 is what I have. Again, I'm going from memory here, but I think the shaft OD is 1.375.

    Hydraulic Pump Quad Ring

    Thanks for your reply. So it sounds like the seal does need to make good contact with the shaft? I"ve tried it both ways. Out of the pump it is sloppy loose, when it"s in the pump body a little harder to tell of course, but with the teflon backup and quad ring in place you can look in from the...

    Hydraulic Pump Quad Ring

    I'm rebuilding the hydraulic pump on my 1974 310 John Deere backhoe. The shaft seal went out. I have replaced the worn (had small grooves worn into it) shaft with a new one and have a new RE29103 seals kit. In checking to make sure things fit right, I tried the outer dust seal on the shaft and...

    310 Backhoe Hydraulics

    Thanks for the great advice. I found the relief valve. With the plug removed, I can move it back and forth with the tips of my pinky fingers but just barely. It's border line on hanging up. I assume it should glide smoothly in it's housing? After removing it I notice there appears to be another...

    Starter will not turn the flywheel

    May be an obvious question...but have you removed the spark plugs when trying to turn it over?

    310 Backhoe Hydraulics

    I purchased a 1974 310 with 6200 hours on it a couple of months ago to use on my farm. Before I used it I changed all of the filters and fluids. I have never used a backhoe before, but it seems like the hydraulics have a volume problem. Everything moves fine if I move one thing at a time, but if...
