Frequently Asked Questions
Q: What is the CR 64133-3 U cup seal?
A: The CR 64133-3 is a Crown OEM U-shaped cup seal for electric lift truck hydraulic cylinder pistons. It creates a dynamic seal to prevent hydraulic fluid leakage during lift and lower cycles on Crown pallet jacks.
Q: What cross-reference and equivalent part numbers exist for the CR 64133-3?
A: The CR 64133-3 supersedes part number 64133-005. Cross-references include CR064133-005, CR064133005, CR 064133-005, CR 64133-5, CROWN064133-005, CROWN064133005, CROWN 064133005, CR64133005, CROWN64133005, CR 64133005, CROWN64133-5, 64133-5, and 64133-005. Use any of these equivalents as replacements.
Q: Can I use CR 64133-5 or 64133-005 instead of CR 64133-3?
A: Yes, the CR 64133-5 and 64133-005 are equivalent and superseded by CR 64133-3. All three part numbers reference the same U cup seal. The CR 64133-3 is the current OEM designation.
Q: What material does the CR 64133-3 seal use?
A: The CR 64133-3 is manufactured from durable elastomeric seal material engineered for Crown hydraulic cylinder applications. It resists pressure cycling, hydraulic fluid exposure, and wear in piston rod dynamic sealing.
Q: How do I know if the CR 64133-3 needs replacement?
A: Replace the CR 64133-3 when you observe internal hydraulic leakage from the cylinder rod, reduced lift speed, or inability to hold load. A failing U cup seal will cause visible fluid weeping at the piston rod area.
Q: Which Crown pallet jack models use the CR 64133-3?
A: The CR 64133-3 is used in Crown electric pallet jack and lift truck hydraulic cylinders. Confirm your specific Crown model and serial number match this seal specification before ordering.
