I've been troubleshooting these issues for a while now, and hopefully with the help of the world wide web, my troubles will soon be over.
I have a '86 JD 310C Backhoe. I'm having trouble with what I believe to be the torque converter/reverser or a component thereof. The hoe will currently not move forward or reverse. If I raise the wheels, I get can minimum spin from the left wheel in reverse. With the weight of the hoe, its barely an attempt at a lunge. I have changed the fluid in the reverser. There were no metal shavings to speak of gathered at the housing magnet. The internal screen filter was 90% clogged with what to me looked like cardboard pieces. After a thorough cleaning, and refilling with fluid.....still nothing. I have disconnected the neutral switch on the front loader controls with no affect. All other hydraulics work fine. I have also checked the tranny fluid. I have done my best to spot anything obvious underneath. This brings me to tonight. I have discovered the the item labeled "A" in the pictures appears to be a "T" fitting with a solenoid in one end, a barbed fitting opposite, and a 1/2" threaded nipple at the "T". (separate picture attached). The solenoid is stuck in the open position and does not actuate when 12 volts is applied. The barbed fitting obviously has a hydraulic line attached, and the 1/2" threaded nipple threads into the side of the reverser in the location shown. Any ideas if this could be my problem, and if not, I would love to hear anybody's opinions. I am also curious what item "B" is. It is attached to the shuttle shift and has a 2 wire plug set attached.
On a separate issue. The hoe has always started on the first crank until this year. Now I could run the battery out trying and it wont even attempt a sputter. If I give it a shot of ether, it starts up and runs great. I can turn it off, and 2 seconds later with the engine hot try it again, and nothing. I have drained the diesel and refueled with fresh diesel with sea foam and another diesel additive, and still nothing. Any ideas.
Sorry so long, but many advanced thanks.
