Frequently Asked Questions
Q: What is the relationship between CR 43023-MP and CR 43023?
A: The CR 43023-MP is the current OEM replacement for CR 43023. Both fit Crown PTH manual pallet jacks with serial numbers 3-183850 and higher. CR 43023-MP supersedes and is interchangeable with the older CR 43023 part number. Use CR 43023-MP for new orders.
Q: What Crown PTH serial numbers does the CR 43023-MP fit?
A: The CR 43023-MP is designed exclusively for Crown PTH manual pallet jacks bearing serial number 3-183850 and higher. Earlier PTH units with lower serial numbers require different seal kits. Always verify the serial number on your pallet jack before ordering.
Q: What seals and components are included in CR 43023-MP?
A: The CR 43023-MP contains abrasion- and corrosion-resistant rubber seals, precision-formed metal rings, and resilient spring elements. This full kit enables complete hydraulic unit rebuild to restore leak-free operation and optimal hydraulic pressure.
Q: What symptoms indicate that the CR 43023-MP seals are needed?
A: Install the CR 43023-MP when you see hydraulic fluid leaking around the pump cylinder, reduced lifting capacity, slower raise speed, jerky lift operation, or visible seepage at seal connections. These indicate seal degradation and loss of hydraulic pressure containment.
Q: What part numbers does CR 43023-MP replace or cross-reference?
A: CR 43023-MP supersedes and replaces CR 43023, 43023, Crown 43023, CR43023, 43023-SUPER, and CR 43023-SUPER. It is the current recommended part for Crown PTH units in the specified serial range and provides equivalent or improved performance to all older equivalent numbers.
