Frequently Asked Questions

Q: What materials are included in the 00591-57579-81 seal kit?
A: This Toyota OEM super seal kit contains oil-resistant NBR (nitrile rubber), PTFE (polytetrafluoroethylene), and polyurethane seals. The kit includes rod, piston, and wiper seals for hydraulic pump systems in Toyota manual pallet jacks.

Q: Which Toyota manual pallet jack models use the 00591-57579-81 seal kit?
A: The 00591-57579-81 is an OEM Toyota part designed for manual pallet jack hydraulic pump systems. This seal kit is compatible with Toyota manual pallet jacks and similar equipment from Crown, Raymond, and Yale that use equivalent hydraulic pump assemblies. Verify your equipment manual or current seal part number before ordering.

Q: When should the seals in the 00591-57579-81 kit be replaced?
A: Replace the seals when you experience hydraulic fluid leaks from the pump rod or piston area, reduced pump pressure, or difficulty raising the load. Seals typically require replacement every 3-5 years depending on usage frequency and storage conditions. Cold storage and wet floor use accelerate seal degradation.

Q: What is the pressure rating for the 00591-57579-81 seal kit?
A: The 00591-57579-81 kit is rated for standard manual pallet jack hydraulic system pressure, typically 5000 PSI maximum working pressure. These seals are designed to restore original OEM sealing performance in Toyota pump systems operating within normal manual pallet jack pressure ranges.

Q: How long do NBR and PTFE seals last in manual pallet jack pumps?
A: NBR seals typically last 3-5 years under normal operating conditions. PTFE provides low-friction performance and extended wear resistance. Polyurethane components offer oil resistance. Lifespan depends on usage frequency, fluid condition, temperature exposure, and storage environment. Inspect seals annually if equipment is used daily or stored in cold or wet conditions.

Q: Is the 00591-57579-81 compatible with other brands of manual pallet jacks?
A: The 00591-57579-81 is a Toyota OEM seal kit. Cross-reference your equipment pump assembly number to verify compatibility. Similar seal kits are available for Crown, Raymond, Yale, and other brands. Do not assume compatibility based on seal size alone, as pump designs vary.
