Komatsu WA-320:
problem with load

Hello! Please tell me what could be the cause:
moving the load, the machine stops completely. The engine does not feel stress at all. On the control panel is a regulator of the effort, but I can not understand how it regulates the hydraulics. as far as I understand, all the executive solenoids have only ON. and off. I hope to help.

Dear Jeff, all loaders (wheeled or on tracks) can be configurated as forklifts.

That effort regulator you found on the dashboard transfers power between hydraulics or march (drive); your wheel loader is a hydrostatic machine: pump for drive with LS, flow and direction controls and two hidromotors for drive, mounted on a drop box.depending of travel speed these motors generate power.
That part code is not a Komat'su genuine.
In case you need a workshop Manual (pdf format), provide an e-mail adress AND the machine generation: 3, 5 or 6 (the number after the dash on the nameplate).

This is a Wheel Loader, not a forklift. So the knowledge to assist you maybe limited here.

Found the reason for failure.
What should be the length of the part UC1700877569 (PIN,PARALLEL)? In the motor N1.
