Q: Is the CR 91681 compatible with other electric lift truck brands?
A: The CR 91681 is designed for Crown electric lift trucks. While some aftermarket replacement units may fit similar equipment, verify mounting dimensions, shaft configuration, and voltage compatibility before ordering.
Q: What is the voltage requirement for the CR 91681?
A: The CR 91681 is rated for 24VDC operation. It is not compatible with 12VDC or 36VDC systems. Confirm your equipment battery voltage before installing.
Q: What are common failure symptoms of the CR 91681 pump motor assembly?
A: Failure symptoms include reduced lift speed, inability to reach full lift height, motor running but no hydraulic output, unusual noise, or complete motor shutdown. Check battery voltage first, then inspect fluid level and filter condition.
Q: How often should the CR 91681 assembly be serviced?
A: Service the CR 91681 according to your equipment manufacturer schedule, typically every 500 to 1000 operating hours. Replace hydraulic fluid and filters regularly to extend assembly lifespan and prevent internal damage.
Q: What material is the CR 91681 pump housing constructed from?
