Frequently Asked Questions
Q: What is the CR 44458 and what is it used for?
A: The CR 44458 is an OEM hydraulic ram assembly for Crown PTH50 manual pallet jacks. It is the core lifting mechanism that generates hydraulic pressure to raise the load.
Q: What is the CR 44458 constructed from?
A: The CR 44458 features a high-strength steel cylinder and piston rod. It uses bushing and bearing pivots for durability and smooth operation. The piston rod is hard chrome-plated to resist wear and corrosion during repeated cycles.
Q: How does the hard chrome plating on the CR 44458 piston rod benefit durability?
A: Hard chrome plating extends the service life of the piston rod by protecting against corrosion, friction wear, and scoring. This coating maintains dimensional accuracy and prevents hydraulic fluid leakage from piston rod damage.
Q: What pins are used with the CR 44458?
A: The CR 44458 attaches to the pallet jack frame using 3/16 inch and 3/8 inch roll pins. These sizes are critical for proper pivot connection and load distribution.
Q: Are there cross-reference or equivalent part numbers for the CR 44458?
A: No cross-reference or equivalent part numbers are available for the CR 44458. It is a proprietary Crown assembly for PTH50 series jacks. Do not attempt to substitute with other brands or models.
Q: What are signs that the CR 44458 hydraulic ram needs replacement?
A: Replace the CR 44458 if the pallet jack will not raise, raises slowly, fails to hold a raised load, or shows external hydraulic fluid leakage around the piston rod or cylinder seams. Loss of pressure indicates internal seal or rod damage.
