CR 300080-034

Frequently Asked Questions

Q: What is the pump cylinder CR 300080-034 designed for?
A: The CR 300080-034 is an OEM pump cylinder component for Crown model 6600 manual pallet jacks. This cylinder houses the hydraulic piston and generates pressure for the lift mechanism. It is a critical component in the hydraulic system that converts manual pump action into vertical load lifting.

Q: Which Crown models use the CR 300080-034 pump cylinder?
A: The CR 300080-034 pump cylinder is designed exclusively for Crown model 6600 manual pallet jacks. Confirm your pallet jack is a Crown 6600 before ordering to ensure proper fitment and function.

Q: What material is the CR 300080-034 pump cylinder constructed from?
A: The CR 300080-034 is manufactured from heavy-duty steel designed to withstand hydraulic pressure cycles and repetitive mechanical stress. The cylinder body is engineered to resist internal corrosion and maintain pressure integrity over extended service periods.

Q: What symptoms indicate the CR 300080-034 pump cylinder needs replacement?
A: Replace the cylinder if the pallet jack loses lifting pressure, develops slow or incomplete lift cycles, exhibits external oil seepage, or if the pump handle moves without generating lift. Internal scoring or seal degradation causes loss of hydraulic efficiency.

Q: What maintenance does the CR 300080-034 pump cylinder require?
A: The cylinder requires periodic verification that hydraulic fluid is at the specified level and that no external leaks are present. Keep the cylinder bore clean and free of debris. Maintain the sealing surfaces and use the correct hydraulic fluid grade specified by Crown for model 6600 pallet jacks.

Q: Are there cross-reference part numbers for the CR 300080-034?
A: The CR 300080-034 is an OEM Crown component with no available cross-reference or equivalent part numbers. Order using the exact part number CR 300080-034 to ensure compatibility with Crown model 6600 pallet jacks.
