Frequently Asked Questions
Q: What does the CR 103639 valve assembly control in a pallet jack?
A: The CR 103639 is a hydraulic valve assembly that regulates fluid flow and pressure direction within the lift system. It controls lowering speed, load holding, and pressure relief to protect the system.
Q: Which Crown models use the CR 103639 valve assembly?
A: The CR 103639 is a Crown OEM valve assembly for specific electric pallet jack models. Confirm your equipment model and serial range for compatibility before ordering.
Q: What symptoms indicate a faulty CR 103639 valve assembly?
A: Signs of valve failure include uncontrolled lowering, inability to lower at all, load drift when parked, loss of pressure, or system over-pressurization. These indicate the valve is not sealing or directing flow correctly.
Q: What is the maximum pressure rating for the CR 103639 valve?
A: Pressure ratings and flow specifications are listed in the component technical data. Contact us with your Crown model for exact valve specifications and pressure relief settings.
Q: Can the CR 103639 valve be repaired or must it be replaced?
A: Hydraulic valves are precision assemblies. If testing confirms internal seal failure or spool stiction, replacement is the standard solution. Repair is not practical for most valve failures.
