Frequently Asked Questions
Q: What is the CR 819180 and where does it go in a pallet jack?
A: The CR 819180 is an OEM O-ring seal for Crown PTH 50 manual pallet jack hydraulic units. O-rings are used in the hydraulic cylinder, pump, and valve assemblies to prevent fluid leakage under pressure.
Q: Which Crown pallet jack models use the CR 819180 O-ring?
A: The CR 819180 is specified for Crown PTH 50 manual pallet jacks with serial numbers 7-512501 and higher. Verify your equipment serial number and hydraulic unit design match before ordering.
Q: What material and size is this O-ring?
A: The CR 819180 is a standard hydraulic O-ring manufactured to OEM specifications. The exact size and material compound depend on which hydraulic component it seals. Always use OEM parts for hydraulic systems to ensure pressure rating and compatibility.
Q: How often should the CR 819180 O-ring be replaced?
A: Replace O-rings when the jack begins leaking hydraulic fluid, loses lifting pressure, or during routine hydraulic unit overhaul. O-ring seals deteriorate over time and should not be reused after removal.
Q: Can the CR 819180 be used as a generic replacement O-ring?
A: No. The CR 819180 is a specific OEM part designed for the Crown PTH 50 hydraulic system. Do not substitute with generic O-rings, as hydraulic systems require precise diameter, thickness, and material compound ratings.
