Frequently Asked Questions
Q: What is the purpose of the CR 077145 hydraulic filter?
A: The CR 077145 is a hydraulic filter designed to remove contamination and particulate matter from hydraulic fluid circulating through Crown electric lift truck systems. A clean hydraulic system ensures precise control of lift, lower, and tilt functions and extends the service life of hydraulic components such as cylinders, pumps, and solenoid valves.
Q: What Crown lift truck models use the CR 077145 filter?
A: The CR 077145 is a Crown OEM filter compatible with Crown electric pallet jacks, stackers, and reach trucks equipped with hydraulic systems. Specific application depends on your truck model and serial range. Verify filter compatibility by cross-referencing your equipment serial number with Crown documentation before ordering.
Q: What are the maintenance intervals for the CR 077145 hydraulic filter?
A: Hydraulic filter replacement intervals depend on operating conditions and fluid contamination levels. Standard maintenance typically requires filter replacement every 1,000 to 2,000 hours of equipment operation, or annually if annual hours are low. Operating in dusty or high-contamination environments may require more frequent changes. Monitor hydraulic fluid condition and follow Crown maintenance schedules for your specific model.
Q: How do I know if the CR 077145 filter needs replacement?
A: Replace the CR 077145 filter if you observe reduced lift or lower speed, sluggish directional control response, visible contamination in the hydraulic fluid sight glass, or if the filter visual indicator signals saturation. A clogged filter restricts fluid flow and forces the system to work harder, causing accelerated wear on hydraulic components.
Q: What type of hydraulic fluid should be used with the CR 077145 filter?
A: The CR 077145 is designed to filter standard Crown ISO 46 hydraulic fluid or equivalent specification fluids recommended by Crown. Verify the correct fluid specification in your equipment maintenance manual. Using non-approved fluid types may reduce filter effectiveness or cause incompatibility issues with seals and hydraulic components.
