Frequently Asked Questions
Q: What is the purpose of the IN 140.6478 valve assembly?
A: The IN 140.6478 valve assembly is a hydraulic control component that regulates pressure and flow direction in the lifting mechanism of manual pallet jacks. It controls whether fluid flows to raise or lower the load.
Q: Which Interthor pallet jack models use the IN 140.6478?
A: The IN 140.6478 valve assembly is compatible with Interthor manual pallet jack models K77 and K85. Confirm your equipment model number before ordering to ensure correct fitment.
Q: What symptoms indicate the IN 140.6478 valve assembly needs replacement?
A: Replace the valve assembly if you observe sluggish or no response when operating the pump handle, inability to hold a raised load, or hydraulic fluid leaking from valve connection points. Loss of pump pressure or erratic lift behavior also indicates valve failure.
Q: How can I verify the IN 140.6478 is the correct replacement part?
A: Cross-reference your pallet jack model (K77 or K85) with the SKU IN 140.6478. Verify the connection ports and mounting configuration match your current valve assembly. If you are unsure, provide your equipment serial number or model for confirmation.
Q: What maintenance extends the life of the IN 140.6478 valve assembly?
A: Maintain proper hydraulic fluid levels and use the correct fluid type specified for your pallet jack. Keep the valve clean and free from dirt contamination. Check hose connections periodically for leaks. Monitor pump response time; sluggish operation may indicate internal valve wear rather than fluid loss.
