    Bobcat 863 - Electrical issues preventing aux usage

    Check your Service Manual for the procedure to test the PWM module. I have two manuals for older loaders and they both have the procedures to back probe the connectors and the normal voltages for both the inputs and outputs for both intermittent and continuous flow My manuals list the outputs...

    Bobcat 863 - Electrical issues preventing aux usage

    My understanding of the C-Series is the Aux solenoid coils are powered by the Pulse Width Modulator (PWM) controller. On my 763 the PWM controller is bolted to the hull below the drivers left arm. Did you check if the AUX spools are stuck? The scraped insulation may be from some attempting...

    6640 gehl, thick white smoke at starting

    Friend of mine has a 5635 that had similar symptoms (hard starting and lots of white smoke on start up). It took a while to find the problem. His partner had changed the fuel filter and did not remove the inner seal (the one that goes around the center threaded nipple). He installed a new...

    Traction Lock intermittent with engine RPM -- what's going on?

    The brake switch is attached to the small Parking Brake Pedal on top of the chain case. I.E. Between your feet when sitting in the loader. Are you saying the newer model loaders don't have a Parking Brake Pedal? As for the ground, follow the black wire at the Parking Brake Solenoid back until...

    Bobcat 753F BOSS system not working

    I was working with my brother today and told him about your issue. His machine at work had the same problem a few years back. They phoned the Bobcat dealer and the Service Manager told them it is a common problem. There is one of the valves on the main block that get fouled and causes this...

    Bobcat 753F BOSS system not working

    Re: Lift and Tilt - could be control valve, pressure relief valve or hydraulic pump. An easy check is to connect a pressure gauge to a flat face connector and plug it into one of the auxiliary lines on the boom. Activate auxiliary hydraulics and use the rocker switch on the right handle to...

    Bobcat 753F BOSS system not working

    I concur with your assessment. The fundamental function of the BOSS system is to monitor hydraulic/engine temperatures and pressures. If it determines that a sender is not sending information or if the sensor data is determined to be outside the safe limits, the BOSS controller removes power...

    Bobcat 753F BOSS system not working

    The first few things to check are: 1. The BOSS fuse in the fuse block. 2. Raise the cab and make sure the BOSS controller has not been removed. I seem to recall it is located under the cab behind the operators left shoulder. 3. There are multiple multi-wire connectors on the BOSS...

    why dont you use a 4in1 bucket?

    A 4in1 is like a Swiss Army Knife and allows you do do a variety of tasks but not optimal for any one thing. The extra weight of the 4in1 is an advantage on my toothed bucket when trying to penetrate in difficult soils. It is my preferred bucket for digging and general work. For load and...
