Frequently Asked Questions

Q: What equipment is the 40184 CR Seal Kit compatible with?
A: This seal kit is designed for manual pallet jacks from major OEM brands including Crown, Toyota, Raymond, Yale, and other standard manual pallet jack models. Verify that your equipment uses a hydraulic pump system before ordering.

Q: What is the maximum pressure rating for the 40184 seal kit?
A: The 40184 CR Seal Kit is rated for hydraulic pressures up to 3000 PSI. Do not use this kit in systems exceeding this pressure specification.

Q: What components and materials are included in the 40184 kit?
A: This kit includes high-grade NBR elastomer shaft seals, O-rings, dust seal ring, U-packing, and spring washer. The seals meet ISO 3601 and SAE J200 standards with Shore A hardness of approximately 70. All components are engineered for full pump reseal applications.

Q: What does NBR elastomer material mean and why is it used?
A: NBR (nitrile rubber) elastomer is a synthetic rubber compound resistant to hydraulic fluid, oil, and general wear. It is the industry standard for hydraulic seal kits because it maintains flexibility and durability under high pressure and temperature cycling in pallet jack pumps.

Q: When should the 40184 seal kit be replaced?
A: Replace this seal kit when you observe hydraulic fluid leakage from the pump, reduced lifting pressure, or a sluggish lift cycle. Preventive replacement is recommended during major pump rebuilds or after 3000 to 5000 operating hours depending on use conditions.
