    Link Belt LS4300 CII no travel

    At this point you should check if the travel spools are still in the main control valve. But know that even with spools in neutral theres still pressure in the main lines,bucket, lifting, arm ,swing and travel, but not enough to mobilize then until the spool are shifted.

So a technician came and worked on the pump,problem didn't go away,so went onto the control valve to inspect spool...

    Cat 950F series 2 wont engage forward nor backward ,just sitting comfortably

    I've seen those set of wires before, are they the ones behind the operator's seat? Just above the ECM?

    Cat 950F series 2 wont engage forward nor backward ,just sitting comfortably

    Tried two other ECM, still the same thing. You're right Nige,ECM now shows 650 F02 error code. This translates to "harness data erratic, intermittent or incorrect "

I've put an ecm from another 950F series 2 Machine now moves, and pushes sand with all the power in the world at start up,but put it to reverse to come back with the bucket of sand it won't move, only attempts to. But if you turn her off and on almost immediately, she...

    Oil used is SAE40 ,how do I do the wire trick? All filters have been changed when previous technicians were troubleshooting why it wasn't moving. Oil is new too,strainer looks good and no metal particles on magnet. I'll check suction lines and tank. I'll test for pressure, thanks

    Cat 950F series 2 wont engage forward nor backward ,just sitting comfortably

    Cat 950F series 2 wont engage forward nor backward ,just sitting comfortably

    Thanks, I don't have ET but I tested the shifter and only the battery + to it has 24 volts, while I engage it in F/R ,1234 there isn't voltage on any other wires. I had thought I'd see voltage move position as I select gears.
