Frequently Asked Questions
Q: What is a CR SUPER SEAL KIT and what does it do?
A: The CR SUPER SEAL KIT is a complete hydraulic seal replacement set engineered for Toyota manual pallet jack hydraulic systems. It contains precision-molded double-lip and single-lip seals with steel reinforcement to prevent hydraulic fluid leakage from pump cylinders, control valve spools, and lift cylinders operating at pressures up to 3000 PSI.
Q: What is the pressure rating for part 00591-43152-81?
A: This seal kit is rated for manual pallet jack hydraulic systems at pressures up to 3000 PSI. The seals are engineered to maintain effectiveness at full pump pressure during load lifting and to handle shock loads during descent and emergency lowering scenarios.
Q: What material properties do these seals have?
A: The seals are manufactured from hydraulic-grade NBR (nitrile rubber) with a hardness specification of Shore A 70 ±5. Nitrile provides excellent resistance to petroleum-based hydraulic fluids, mineral oils, and maintains elasticity across the typical operating temperature range of minus 20 to plus 100 degrees Celsius. The double-lip design with steel reinforcement provides superior pressure retention.
Q: How do I know if the hydraulic seals need replacement?
A: Signs of seal failure include visible hydraulic fluid leakage around pump housing, control valve, or lift cylinder rod, inability to build lifting pressure, slow or no load holding, and fluid dripping from the jack when parked. Seal degradation is accelerated by contaminated hydraulic fluid, excessive heat, or long storage periods.
Q: How long should these seals last in Toyota manual pallet jacks?
A: Under normal operating conditions with regular hydraulic fluid changes, this seal kit provides 3 to 5 years of service life or 8000 to 12000 pallet jack cycles. Seals degrade faster in applications with high ambient temperatures, frequent duty cycles, or use of contaminated or incorrect hydraulic fluid grades.
Q: Are there cross-reference part numbers for this seal kit?
A: Part number 00591-43152-81 is the OEM specification for Toyota manual pallet jacks. When ordering seal kits for other brands such as Crown or Raymond pallet jacks, confirm seal bore diameters and pressure ratings match your equipment, as hydraulic system geometries vary between manufacturers.
