Frequently Asked Questions
Q: What does the CRN-43023-1 hydraulic seal kit contain?
A: The CRN-43023-1 is a comprehensive hydraulic seal kit that includes all essential nitrile O-rings, gaskets, and seals required for full hydraulic system overhaul. It utilizes oil-resistant NBR elastomers and zinc-plated steel retainers for optimal sealing performance.
Q: Which Crown pallet jack models and serial ranges does CRN-43023-1 fit?
A: The CRN-43023-1 is engineered for Crown PTH manual pallet jack hydraulic units with serial number 3-183850 and above. Verify your equipment serial number matches this threshold before ordering to ensure compatibility.
Q: What are the equivalent part numbers and cross-references for CRN-43023-1?
A: The CRN-43023-1 is equivalent to CR43023 and replaces 43023-1. The OEM part number is CRN-43023-1 and the manufacturer part number is 43023. This kit provides comprehensive coverage for a complete hydraulic system service.
Q: What hydraulic system pressure rating does this kit support?
A: The CRN-43023-1 is specified for 3000 PSI hydraulic systems, which is standard for Crown PTH series manual pallet jacks. The NBR elastomer and steel components are rated for this pressure range and typical warehouse duty cycles.
Q: When should the CRN-43023-1 seal kit be used versus individual seal replacement?
A: Use the complete CRN-43023-1 kit for full hydraulic system overhauls to ensure all sealing surfaces are replaced simultaneously, preventing piecemeal failures and cross-contamination. Individual seal failure, persistent slow leaks, or jack age above 5-7 years justifies a complete kit replacement for reliability.
Q: What material are the seals made from and why does this matter?
A: The seals are made from oil-resistant NBR (nitrile) elastomer with zinc-plated steel retainers. NBR resists standard hydraulic oils and maintains flexibility across typical warehouse temperatures. Zinc plating prevents corrosion of steel components in humid or outdoor environments.
