Seal Kit for Crown, Toyota Manual Pallet Jack

Frequently Asked Questions

Q: Which makes and models is the 00591-04385-81 seal kit compatible with?
A: The 00591-04385-81 seal kit is compatible with Crown and Toyota manual pallet jacks. It fits hydraulic pumps and cylinders that use this seal configuration. Cross-reference your jack model and hydraulic pump serial number with the specification sheet to confirm compatibility.

Q: What material are the seals in the 00591-04385-81 kit made of?
A: The seals in the 00591-04385-81 kit are made of nitrile elastomer, which is suitable for hydraulic pressure sealing applications. This material provides durability and resistance to common hydraulic fluids.

Q: How can I tell when the seals in the 00591-04385-81 kit need to be replaced?
A: Replace the seals when you notice hydraulic fluid leaking from pump or cylinder rod areas, especially after lifting loads. Sluggish lift cycles and discolored or contaminated fluid are also signs of seal wear. Preventive replacement every 5 to 7 years is recommended for high-use equipment.

Q: What should I do if my manual pallet jack is leaking but still lifting?
A: A slowly leaking jack may still lift, but you will lose pressure during operation and the load may drift down unpredictably. Do not operate the equipment if seals are severely degraded, as the load can drop suddenly and create a safety hazard. Replace the seals as soon as leaks are confirmed.
