BRUSH SET
Frequently Asked Questions
Q: When do brush sets need to be replaced?
A: Replace brushes when you observe reduced motor power, intermittent operation, stuttering or chattering during pump cycles, or visible brush wear below 5mm length. Worn brushes cause erratic lift performance and can damage the commutator.
Q: What motors does the BR 27327-121 brush set fit?
A: The BR 27327-121 is compatible with 24V DC motors used in lift truck applications. Verify brush terminal configuration and brush holder dimensions match your motor before ordering.
Q: What is the typical lifespan of brush sets?
A: Brush lifespan ranges from 2-5 years depending on motor run time, load conditions, and maintenance practices. Heavy-duty applications with frequent on-off cycling experience faster brush wear than continuous-run equipment.
Q: How do I know if motor brushes are failing without removing them?
A: Watch for loss of lift pressure, delay in pump response, increased motor noise, or arcing visible from the motor ventilation ports. A multimeter can measure brush resistance. If resistance exceeds normal baseline values, brushes need replacement.
Q: What material are these brushes made of?
A: The BR 27327-121 brushes are composed of carbon composite material designed for reliable commutation in DC motors. The specific compound depends on motor application. Verify brush dimensions and resistance rating match your motor specification.
