Frequently Asked Questions
Q: What is the CR 819934-SUPER and how does it differ from the standard seal kit?
A: The CR 819934-SUPER is a premium hydraulic seal kit for Crown PTH 50 manual pallet jacks. Unlike the standard CR 819934, the SUPER version includes the complete pump piston assembly along with all seals and backup washers needed for a full hydraulic pump rebuild.
Q: Which pallet jack models does the CR 819934-SUPER fit?
A: The CR 819934-SUPER is designed for Crown PTH 50 manual pallet jacks with serial numbers 7-512501 and higher. It is also compatible with Raymond model 8300, 8400, and 8500 pallet jacks that share compatible hydraulic pump architecture. Confirm your equipment serial number and model before ordering.
Q: What materials are used in the CR 819934-SUPER kit?
A: The CR 819934-SUPER contains premium nitrile and PTFE sealing materials engineered for high-pressure hydraulic applications. The pump piston is precision-machined steel designed to maintain pressure and durability under continuous operation.
Q: What hydraulic oil should be used with the CR 819934-SUPER seals?
A: The CR 819934-SUPER is compatible with standard ISO 32 and ISO 46 hydraulic oils. Use only manufacturer-recommended hydraulic fluid to ensure seal compatibility and system performance.
Q: When should the CR 819934-SUPER be ordered instead of the standard CR 819934?
A: Order the CR 819934-SUPER when the hydraulic pump requires both seal replacement and piston replacement. If only seals are leaking and the pump piston is in good condition, the standard CR 819934 kit is sufficient.
Q: What is the cross-reference relationship between CR 819934 and CR 819934-SUPER?
A: The CR 819934-SUPER supersedes and replaces the standard 819934 when a complete pump rebuild is required. Both kits use identical seal material specifications but SUPER includes the pump piston assembly. The part numbers CR819934 and 819934 are cross-references to the standard kit.
