Frequently Asked Questions
Q: What components are included in the 40633 Crown seal kit?
A: The 40633 Crown seal kit includes U-cup seals, wiper seals, O-rings, and bushings. All components are manufactured from oil-resistant nitrile rubber and polymer composites engineered for Crown manual pallet jack hydraulic cylinders.
Q: What hydraulic fluid should be used with the 40633 seal kit?
A: The 40633 kit is compatible with mineral oil-based hydraulic fluids at ISO VG 32 viscosity. Do not use synthetic, water-based, or other fluid types, as they may degrade the seal materials and cause leakage.
Q: What is the rated duty cycle for the 40633 seal kit?
A: The 40633 seal kit is rated for continuous manual pallet jack operation, supporting up to 300 pump cycles per 24-hour period. This covers typical warehouse and material handling applications.
Q: Which Crown pallet jack models are compatible with the 40633 seal kit?
A: The 40633 kit is engineered for selected Crown manual pallet jack models. Verify your equipment model number and serial range against the compatibility list before ordering to ensure correct fitment.
Q: How long does a 40633 seal kit typically last in service?
A: Seal kit lifespan depends on operating conditions, fluid maintenance, and usage intensity. In typical warehouse environments with proper oil maintenance, the 40633 kit can provide 2-4 years of service before wear requires replacement.
Q: What pressure rating do the seals in the 40633 kit support?
A: The 40633 seal kit components are engineered to withstand the rated system pressures of Crown manual pallet jack hydraulic cylinders during normal lift and load-holding operations.
