Frequently Asked Questions

Q: What is the 00591-55626-81 Toyota Super Seal Kit used for?
A: The 00591-55626-81 is an OEM seal replacement kit designed for the pump assembly in Toyota manual pallet jack hydraulic systems. It provides primary and secondary seals for pump rod and cylinder interfaces, restoring hydraulic containment and pressure integrity.

Q: What is the pressure rating of the 00591-55626-81 seal kit?
A: The seal kit is engineered for hydraulic systems operating up to 3000 PSI working pressure. This rating covers standard manual pallet jack pump assemblies under normal load handling. Do not use in systems exceeding 3000 PSI.

Q: What material are the seals in the 00591-55626-81 kit?
A: The kit contains high-density NBR (nitrile butadiene rubber) seals with a hardness rating of 70 Shore A per ASTM D2240. NBR is standard for mineral oil hydraulic systems and resists degradation from heat and pressure cycling common in warehouse pallet jacks.

Q: Which Toyota manual pallet jack models use the 00591-55626-81 seal kit?
A: This seal kit fits select Toyota manual pallet jack models with the matching pump assembly design. Fitment is model and pump revision specific. Confirm your pallet jack model and pump assembly ID with us before ordering to ensure correct seals.

Q: What are the signs that the 00591-55626-81 seals need replacement?
A: Replace seals if you observe external oil leakage around the pump rod or cylinder connection, loss of hydraulic pressure, or inability to maintain load. Seals typically last 3 to 5 years of regular warehouse use. Continued operation with failed seals risks loss of lift capacity.

Q: What does the 00591-55626-81 kit include?
A: The Super Seal Kit includes all primary and secondary seals required for the pump assembly. Verify the exact seal quantity and configuration match your pump model. Contact us with your pump assembly number for a complete kit contents list.
