Frequently Asked Questions
Q: What materials make up the 800086747 hydraulic seal kit?
A: The 800086747 contains nitrile rubber (NBR) O-ring seals at 70 Shore A hardness, polyurethane wiper seals, and PTFE backup rings. This combination restores both main pump and cylinder seal integrity under sustained pressure and prevents contamination ingress.
Q: What pressure rating does the 800086747 seal kit handle?
A: The 800086747 is engineered for mineral oil hydraulic systems operating at maximum 3000 PSI. This pressure rating is typical for main lift ram applications in manual pallet jacks. Do not exceed 3000 PSI to prevent seal extrusion and system failure.
Q: What bore size is the 800086747 seal kit designed for?
A: The 800086747 is designed for the typical main lift ram bore of 31.5 mm. Confirm your cylinder bore diameter matches 31.5 mm before ordering to ensure proper seal fit and pressure retention.
Q: Which pallet jack models use the 800086747 seal kit?
A: The 800086747 is compatible with manual pallet jack hydraulic systems from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers using 31.5 mm main lift cylinder bore and mineral oil systems rated to 3000 PSI. Verify your equipment hydraulic unit part number and bore size before ordering.
