Frequently Asked Questions
Q: What is included in the 00591-53459-81 mobile seal kit?
A: The 00591-53459-81 is a complete seal kit for forklift hydraulic cylinders rated to 3000 PSI. It includes NBR rubber O-rings with Shore A 70±5 hardness and polyurethane dust seals conforming to ISO 5597 profile specifications. All seals are factory-machined to ±0.005 inch tolerance for precise bore fitment.
Q: What hydraulic fluids are compatible with the 00591-53459-81 seal kit?
A: The NBR and polyurethane seals in the 00591-53459-81 are rated for petroleum-based hydraulic fluids. Do not use synthetic or water-based fluids without verifying compatibility. Using incompatible fluids will cause seal degradation and premature cylinder failure.
Q: What is the service life of the 00591-53459-81 seals?
A: The 00591-53459-81 seals are tested for a minimum of 400,000 cycles under rated pressure. Actual service life depends on operating pressure cycles, fluid condition, contamination levels, and temperature. Maintain hydraulic fluid cleanliness to maximize seal longevity.
Q: How do I know which cylinder size needs the 00591-53459-81 seal kit?
A: The 00591-53459-81 is sized for a specific cylinder bore diameter and rod diameter. Verify your cylinder dimensions against the kit specifications. Using incorrect seal sizes results in leakage, loss of hydraulic pressure, and inoperative forks. Contact us with your cylinder bore and rod measurements for proper part identification.
Q: What is the maximum pressure rating for the 00591-53459-81 seal kit?
A: The 00591-53459-81 seal kit is rated for hydraulic systems up to 3000 PSI. Operating at or exceeding this pressure with these seals risks blowout, internal leakage, and cylinder failure. If your system requires higher pressure ratings, confirm proper seal specification before ordering.
