CR 40118

Frequently Asked Questions

Q: What is the CR 40118 and what does it do?
A: The CR 40118 is an OEM valve spring designed for the hydraulic pump valve assembly on Crown PTH Series manual pallet jacks. It maintains precise hydraulic control and system reliability under rated 5000 lbs load capacity. This is a direct OEM replacement component.

Q: Which Crown pallet jack models use the CR 40118 valve spring?
A: The CR 40118 is engineered for Crown PTH Series manual pallet jacks. The alternate model designation is CR40118. Always verify your equipment model and serial range against Crown documentation before ordering to confirm this part fits your specific unit.

Q: What material is the CR 40118 spring and why is that important?
A: The CR 40118 is manufactured from high-carbon oil-tempered steel. This material is chosen because oil-tempered steel resists corrosion from hydraulic fluid exposure, maintains constant spring tension under high-pressure cycles, and provides the reliability needed in hydraulic pump assemblies operating at full 5000 lbs load capacity.

Q: Is there a cross-reference or supersession number for CR 40118?
A: No official cross-referenced or superseded part numbers are published for the CR 40118. Use the original OEM part number CR 40118 when ordering to ensure correct fitment on Crown PTH Series pallet jacks.

Q: What happens if the CR 40118 valve spring fails or wears out?
A: A faulty valve spring can result in inconsistent hydraulic pressure, sluggish pump response, difficulty lifting or lowering loads, or complete loss of hydraulic function. The CR 40118 must maintain proper tension to control hydraulic flow through the pump valve. If you experience erratic lifting behavior or pressure issues on a Crown PTH Series pallet jack, a worn valve spring may be the cause.
