Frequently Asked Questions
Q: What is the CR 41181 filler plug used for?
A: The CR 41181 is an OEM hydraulic fluid reservoir closure for Crown manual pallet jack hydraulic units. It seals the fill opening and prevents contamination of the hydraulic system during operation and storage.
Q: Which Crown pallet jack models are compatible with the CR 41181?
A: The CR 41181 fits Crown PTH Series, PTH-LATER, and PTH50 Series manual pallet jacks with serial numbers 3-183850 and higher for PTH models and 7-512501 and higher for PTH50 models. It is not compatible with electric pallet jacks.
Q: What material is the CR 41181 filler plug made from?
A: The CR 41181 is molded from thermoplastic or high-strength nylon. These materials provide non-loadbearing sealing at rated hydraulic pressures while resisting degradation from mineral-based hydraulic fluid exposure.
Q: What pressure rating does the CR 41181 support?
A: The CR 41181 is designed for non-loadbearing sealing duty, meaning the plug itself does not carry system pressure. It closes the fill opening only. Always verify the jacket rating of your specific hydraulic unit to confirm system pressure limits.
Q: Are there cross-reference part numbers for the CR 41181?
A: The CR 41181 can also be referenced as 41181 or Crown 41181. Use the exact SKU CR 41181 when ordering to ensure correct fitment. Substituting non-OEM plugs may cause hydraulic fluid leakage or contamination.
