Frequently Asked Questions

Q: What does a hydraulic CR seal kit do on a manual pallet jack?
A: The hydraulic CR seal kit restores the sealing integrity of the pump assembly. It includes oil-resistant seals for the piston, rod, and release valve. These seals prevent hydraulic fluid leakage and maintain pressure needed to raise and lower the jack forks.

Q: Which manual pallet jacks is this seal kit compatible with?
A: SKU 800075702 is designed for standard manual pallet jack pump assemblies used by Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers. Always verify pump model and serial range compatibility before ordering.

Q: What materials are included in this hydraulic seal kit?
A: This seal kit includes oil-resistant NBR (nitrile rubber) and polyurethane seals engineered to ISO 3601-1 tolerances. These materials provide superior resistance to mineral hydraulic fluids and temperature variations common in material handling equipment.

Q: What symptoms indicate a failed or degraded seal kit?
A: Replace the seal kit if you observe hydraulic fluid leaking from the pump assembly, inability to maintain lift height, slow or incomplete raising of forks, hissing sounds from the pump, or visible fluid dripping beneath the jack. These indicate seal failure.

Q: How often should a hydraulic CR seal kit be replaced?
A: Seal kit replacement depends on usage frequency and environment. Heavy-duty operations or exposure to moisture may require replacement every 1-3 years. Monitor for fluid leakage and perform routine inspections to determine when seals are degraded.

Q: Does this seal kit include all necessary components for the pump assembly?
A: SKU 800075702 includes CR seals for piston, rod, and release valve components. Verify your pump configuration to ensure all required seals are included. Some pump assemblies may require additional component kits.
