Frequently Asked Questions
Q: What equipment does this seal kit fit?
A: This seal kit is designed for Toyota manual pallet jacks with hydraulic lift cylinders. It is also compatible with equivalent models from Crown, Raymond, and similar manufacturers that use the same rod diameter and bore diameter specifications. Verify your cylinder dimensions before ordering.
Q: What are the material specifications for these seals?
A: The rod and piston seals are made from high-performance polyurethane with a hardness rating of 85 Shore A. The O-rings are constructed from nitrile rubber with a hardness rating of 70 Shore A. This combination ensures durability in hydraulic fluid environments and is suitable for temperatures ranging from -25°C to +120°C.
Q: When should this seal kit be replaced?
A: Replace this seal kit if you notice hydraulic fluid leakage from the lift cylinder, loss of lifting pressure, or if the cylinder no longer holds load when fully raised. Seal wear typically occurs after 2–5 years of regular use, depending on operating conditions and hydraulic fluid maintenance. Contaminated hydraulic fluid can accelerate seal degradation.
Q: What are the cross-reference part numbers for this kit?
A: The part number and manufacturer part number are both 00591-75311-81. This is a Toyota replacement seal kit with no direct cross-reference to aftermarket brands. Always verify that your cylinder dimensions match the specified rod diameter and bore diameter before ordering to ensure proper fit.
Q: How should these seals be stored before use?
A: Store this seal kit in its original packaging in a cool, dry location away from direct sunlight and extreme temperatures. Keep the seals protected from dust, dirt, and hydraulic fluid contamination until they are ready to be used. Properly stored seals maintain their elasticity and performance characteristics for several years.
Q: What is the working pressure rating of these seals?
A: These seals are rated for working pressures up to 3000 PSI, making them suitable for use in hydraulic systems that operate within this range.
