Frequently Asked Questions
Q: What Crown electric lift truck models use the CR 091681 pump and motor assembly?
A: The CR 091681 is a 24V pump and motor assembly for Crown walkie stackers and pallet jacks. Verify your specific vehicle model and serial number to confirm compatibility, as pump displacement and motor shaft configuration vary by application.
Q: What are the output specifications for the CR 091681?
A: The CR 091681 delivers 24VDC motor power with a specific displacement pump rated in cubic centimeters per revolution. Typical outputs range from 5 to 15 GPM depending on motor RPM and pump type. Check Crown specs for your exact model.
Q: What common failure symptoms indicate the CR 091681 needs replacement?
A: Red flags include weak or no lift, slow hydraulic response, unusual noise or grinding from the motor, visible leaking from pump seals, or voltage drop under load. If the motor does not spin freely when disconnected, internal damage is likely.
Q: What duty cycle is the CR 091681 designed for?
A: Crown pump and motor assemblies are typically rated for intermittent duty with 20 to 40 percent run time. Continuous full-power operation reduces bearing and seal life significantly. Monitor motor temperature during extended use.
Q: How long does the CR 091681 typically last in service?
A: With proper maintenance and normal duty, the CR 091681 lasts 3 to 5 years. High ambient temperature, contaminated hydraulic fluid, or over-voltage operation shortens life to 1 to 2 years. Replace when bearing noise appears or pressure output drops.
