Frequently Asked Questions
Q: What is the PM310757-000 and what equipment does it fit?
A: The PM310757-000 is a 24VDC electric pump motor for electric lift truck applications. It is cross-referenced with Prestolite part number PL46-2458 and FI305915. This motor is compatible with multiple electric lift truck models using 24VDC hydraulic pump motor systems.
Q: What are the key specifications of the PM310757-000 motor?
A: The PM310757-000 operates at 24VDC nominal voltage and is rated for continuous duty in electric lift truck pump applications. Motor mounting configuration, shaft diameter, and pump coupling type should be verified against your equipment specifications before ordering.
Q: Is the PM310757-000 equivalent to Prestolite PL46-2458 or FI305915?
A: Yes. The PM310757-000, Prestolite PL46-2458, and FI305915 are functionally equivalent 24VDC pump motors. Cross-reference your equipment documentation to confirm mounting and shaft compatibility, as minor flange or coupling variations may exist between manufacturers.
Q: What voltage range is acceptable for the PM310757-000 motor?
A: The PM310757-000 is rated for 24VDC nominal operation. Sustained voltage below 20 volts reduces motor speed and lift performance. Voltage above 28 volts may damage motor windings or electronic controls.
Q: How long is the typical service life of the PM310757-000 motor?
A: Service life depends on duty cycle, load conditions, and maintenance. Regularly check battery voltage, motor cooling fins, and electrical connections. Replace the motor if it produces grinding noise, fails to start at nominal voltage, or draws excessive current.
Q: Can the PM310757-000 be repaired or does it require replacement?
A: The PM310757-000 is not field-repairable. If the motor fails to operate or runs intermittently despite good battery voltage and clean electrical connections, the entire motor assembly must be replaced.
