Frequently Asked Questions
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: 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.
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: What is the material durability of the 40184 seal kit?
A: The seals are made from high-grade NBR elastomer, which is engineered to withstand harsh operating conditions and maintain performance over time.
