Cat 336 keeps loosing boom function

Justin98 · 2025-08-10 22:03

Im working on a cat 336 excavator, the serial number is CAT0336ECRZA00244. The operator that’s been running it says that it keeps losing the boom function. So I pulled the codes from the monitor and it has 735-6 code, that reads heavy lift solenoid. Can anybody please help me locate this solenoid on the machine so I can check it and the wiring please Thank y’all in advance for the help

    This should get you where you need to be. If you want a complete machine schematic just ask.
