Frequently Asked Questions
Q: What components are in the A000035639 seal kit?
A: The kit includes high-performance seals, O-rings, dust seals, back-up rings, and retaining rings. All components are precision-manufactured from NBR elastomers and PTFE polymers for superior performance in hydraulic pump restoration on manual pallet jacks.
Q: What equipment does this seal kit fit?
A: This hydraulic seal kit is engineered for manual pallet jack pumps from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other manual pallet jack manufacturers. Verify your pump model and serial range against this part number before ordering.
Q: What materials does this seal kit use?
A: The kit uses NBR (nitrile) rubber per ASTM D2000 for O-rings, PTFE (polytetrafluoroethylene) for back-up rings, and spring steel per ASTM A228 for retaining rings. These materials provide superior compatibility with standard hydraulic oils and extended durability in pressure cycling.
Q: What is the expected service life?
A: Under normal warehouse conditions with proper hydraulic fluid maintenance, expect 3 to 5 years of service from this kit. Superior elastomer and PTFE materials resist degradation longer than standard seals. Lifespan varies with fluid cleanliness and temperature conditions.
Q: What symptoms indicate seal replacement is needed?
A: Replace seals if hydraulic fluid leaks from the pump area, lift performance becomes weak or intermittent, fluid discolors or becomes cloudy (indicating water contamination), or you notice grinding, squealing, or unusual sounds from the hydraulic pump during operation.
