Frequently Asked Questions
Q: What does the CR 819934 hydraulic seal kit contain?
A: The CR 819934 is an OEM hydraulic seal kit for Crown PTH 50 manual pallet jacks. It includes Buna-N O-rings, high-pressure seals, backup washers, and piston components needed to rebuild the pump, cylinder, and valve assemblies in the hydraulic unit.
Q: Which Crown pallet jack models use the CR 819934 seal kit?
A: The CR 819934 is designed for Crown PTH 50 manual pallet jacks with serial numbers 7-512501 and higher. The kit is also cross-referenced for use with equipment rated at 5500 lbs load capacity. Verify your serial number range before ordering.
Q: What materials are used in the CR 819934 seal kit?
A: The CR 819934 contains Buna-N (nitrile) elastomer seals and backup washers manufactured to withstand high-pressure hydraulic environments. These materials are compatible with standard ISO 32 and ISO 46 hydraulic oils.
Q: When should the CR 819934 seal kit be used?
A: Use the CR 819934 when the hydraulic unit leaks fluid persistently, loses lifting pressure, or during routine overhaul. This kit is designed for complete hydraulic system rebuild and should be used as a full set, not partial replacement.
Q: Is the CR 819934 the same as the CR 819934-SUPER?
A: No. The CR 819934-SUPER is a premium upgrade kit that includes additional components such as the pump piston assembly. The standard CR 819934 contains seal components only. Choose based on whether your hydraulic pump requires piston replacement.
Q: Are there cross-reference part numbers for the CR 819934?
A: Yes. The CR 819934 is cross-referenced as 819934 and CR819934-SUPER when the pump piston is included. Verify the exact kit contents match your hydraulic unit rebuild requirements.
