Frequently Asked Questions
Q: What is the CR 816815 pump cylinder and which pallet jacks does it fit?
A: The CR 816815 is an OEM hydraulic pump cylinder designed for Crown PTH50 manual pallet jacks. It is a precision steel cylinder tube component that forms the core of the hydraulic lift system.
Q: Which Crown PTH50 serial numbers is the CR 816815 compatible with?
A: The CR 816815 pump cylinder is compatible with Crown PTH50 units with serial number 7-512501 and above. Verify your pallet jack serial number before ordering to confirm compatibility.
Q: What capacity and load specifications does the CR 816815 support?
A: The CR 816815 is engineered for Crown PTH50 manual pallet jacks rated up to 5000 lbs at a 24 inch load center. The cylinder is designed to operate within standard manual pallet jack hydraulic pressures and duty cycles.
Q: What materials and construction does the CR 816815 use?
A: The CR 816815 is constructed from precision machined steel cylinder tube. Steel provides high strength and durability for repeated lifting cycles under load. The precision machining ensures proper hydraulic seal function.
Q: What seal kit applies to the CR 816815 pump cylinder?
A: The CR 819934 seal kit applies to the CR 816815 pump cylinder. This seal kit provides replacement seals and gaskets for maintaining hydraulic integrity. Order the seal kit separately when rebuilding or servicing the cylinder.
Q: What is the expected service life of the CR 816815 cylinder?
A: The CR 816815 service life depends on duty cycle frequency, load consistency, maintenance, and hydraulic fluid condition. High-cycle operations may require replacement sooner than light-duty use. Regular seal and fluid maintenance extends cylinder lifespan.
