Frequently Asked Questions
Q: What does the TO 00591-40458-81 seal kit contain?
A: The TO 00591-40458-81 is an OEM hydraulic seal kit for Toyota electric lift trucks. It contains hydraulic-grade lip seals with Shore A 85 hardness engineered for lift cylinder piston and rod interfaces, designed to prevent hydraulic fluid leakage under 3000 PSI operational pressures.
Q: Which Toyota lift truck models does the TO 00591-40458-81 fit?
A: The TO 00591-40458-81 is a direct-fit seal kit for Toyota lift cylinder assemblies. Verify your equipment model and cylinder specification before ordering to ensure compatibility with your specific lift truck.
Q: What material are the seals in the TO 00591-40458-81 made from?
A: The seals are constructed from nitrile rubber with Shore A hardness of 85 plus or minus 5. Nitrile provides excellent resistance to hydraulic fluids, thermal cycling, and mechanical wear in lift cylinder service.
Q: What is the maximum pressure rating for the TO 00591-40458-81 seal kit?
A: The TO 00591-40458-81 is engineered for 3000 PSI hydraulic applications. It provides reliable sealing at full-load lift truck operation. Do not exceed the rated pressure specification.
Q: How long does the TO 00591-40458-81 seal kit last?
A: The TO 00591-40458-81 provides long service life under normal operational conditions. Lifespan depends on fluid condition, temperature cycling, and usage frequency. Replace if fluid leakage appears at cylinder rod or piston interface or if hydraulic pressure drops unexpectedly.
Q: Does the TO 00591-40458-81 include installation tolerances and specifications?
A: Yes. The TO 00591-40458-81 meets Toyota OEM installation tolerances for industry-standard lift cylinder interfaces. Seals are precision-manufactured for proper fit without modification. Verify your cylinder bore and rod dimensions match the kit specification.
