Hoist Control - Adjust
The hoist valve LOWER position is an adjustable parameter in the Chassis Electronic Control Module (Chassis ECM) by using Electronic Technician (ET). Adjusting the hoist valve compensates for differences in the valve. Adjusting the hoist valve modifies the speed of the lowering of the truck body.
The process for adjustment has two components:
- Adjust the position sensor for the truck body.
- Adjust the hoist lower valve.
Refer to the procedures in Special Instruction, REHS5088, "773G Off-Highway Truck And 775G Off-Highway Truck Assembly Procedure", "Adjust the Position Sensor for the Truck Body", and "Adjustment for Hoist Lower Valve".
Note: Special Instruction, REHS5088, "773G Off-Highway Truck And 775G Off-Highway Truck Assembly Procedure" is not yet complete.
