Frequently Asked Questions
Q: What equipment does the YL 057457400 brush set fit?
A: The YL 057457400 is a brush set for Yale electric lift truck motors, typically for medium-duty and heavy-duty motor applications. This set is compatible with Yale three-phase electric motors in 24V, 36V, and 48V configurations. Verify your motor voltage and frame size before ordering.
Q: How many brushes are included in the YL 057457400 set?
A: The YL 057457400 brush set typically contains four carbon brushes designed to maintain consistent electrical contact on the motor commutator. Some motor types use two brushes per pole, while others use four total. Confirm your specific motor configuration.
Q: What material are the YL 057457400 brushes made from?
A: The brushes are carbon-graphite composite, designed for high-current DC motor applications. This material provides long wear life, low sparking, and minimal commutator wear. The brush grade is matched to your motor amperage and duty cycle.
Q: When should the YL 057457400 brushes be replaced?
A: Replace brushes when they wear down to approximately 1/4 inch length, when you observe motor sparking, loss of power, or sluggish performance. Under continuous heavy use, brush life is typically 12 to 24 months. Light intermittent use extends brush lifespan to 36 months or more.
Q: What symptoms indicate the YL 057457400 brushes need replacement?
A: Common warning signs include visible arcing or sparking at the brush holder, reduced motor speed or torque, audible chattering or grinding noise, and burned brush holders. Motor performance degradation typically occurs before visible brush damage becomes obvious.
Q: Are there cross-reference brush sets compatible with the YL 057457400?
A: Cross-reference brush sets exist for Raymond, Crown, Toyota, and Hyster equipment with compatible motor types. However, brush specification depends on exact motor amperage, commutator diameter, and spring tension. Contact us with your motor frame size and nameplate rating for alternatives.
