Frequently Asked Questions
Q: What Crown equipment does the CR 43023 hydraulic seal kit fit?
A: The CR 43023 is designed for Crown PTH Series manual pallet jacks with serial numbers 3-183850 and higher. This kit is specific to the hydraulic unit used in that model and serial range. Verify your pallet jack serial number before ordering.
Q: What seals and components are included in the CR 43023 kit?
A: The CR 43023 contains all primary seals required for full hydraulic unit servicing. This includes oil-resistant elastomer seals, precision-formed rings, and spring elements necessary for complete hydraulic system rebuild of the Crown PTH unit.
Q: What material are the seals, and why are they oil-resistant?
A: The CR 43023 seals are constructed from oil-resistant elastomer compounds designed to withstand continuous contact with hydraulic fluid. Oil-resistant material prevents degradation and swelling that would occur with standard rubber, ensuring long-term sealing performance and preventing leakage in the hydraulic circuit.
Q: What failure symptoms indicate the CR 43023 seals need replacement?
A: Signs of hydraulic seal failure include visible fluid leaks from the cylinder or pump area, loss of lifting pressure or raising height, slow or jerky lift operation, or puddles of hydraulic fluid around the pump unit. Any of these symptoms means seals have likely failed and the kit should be installed.
Q: Are there equivalent or cross-reference part numbers for CR 43023?
A: The CR 43023 is the OEM Crown part number. Cross-reference numbers include 43023 and Crown 43023. The superseded version CR 43023-SUPER is an enhanced aftermarket alternative. The newer version CR 43023-MP also replaces this part for PTH units in the specified serial range.
