    Backhoe part question on dipper

    I have a Case 680E backhoe. I am new to Heavy Equipment repair, so I wanted to reach out and ask this silly question. There are 2 plates that attack the hoe bucket to the dipper arm. Yesterday, while sweeping dirt to level it out a bit, I side hit a big rock and snapped one of these plates...

    case 680E motor swap

    The oil pan is gone, and the hydraulic pump needs a front bearing. If you are still interested in the pump let me know.... Anyone have the wiring diagram for the start circuit for the 1978 680e with a 336 engine? The manual doesn't show wire colors from the key switch.

    case 680E motor swap

    I'll see what I can do with the oil pan. I may be able to get it back. I have all other parts of this tractor available (Except the engine) including the compressor and hydraulic pump, radiator, intake and exhaust manifolds, water manifold, all hydraulics and pistons.

    case 680E motor swap

    Thanks for the reply. This particular motor has the spline on front that drives the hydraulic pump. Ended up buying a whole machine that had a bad tranny, just to pull the motor for my swap. Have plenty of spare parts now! Was told that the 336 is a very strong motor, and the machine was worth...

    Well, after finally pulling the motor out and having a mechanic take a look. whoever owned the backhoe before me hade the motor rebuilt recently. Problem was that the JERK who rebuilt it left 2 connecting rod bolts loose. Found the 2 rod bolts in the pan. Crank junk, rod bent, 2 valves bent and...
