Frequently Asked Questions
Q: What is the BR 27793-011 brush spring set?
A: The BR 27793-011 is a brush spring set that applies constant pressure to the carbon brushes in electric lift truck motors. The springs maintain proper contact between brushes and the commutator, ensuring consistent electrical conductivity and reliable motor performance.
Q: Why is the brush spring set important for electric lift truck motors?
A: Brush springs maintain the correct pressure and contact force between brushes and the rotating commutator. Without proper spring tension, brushes may lose contact, causing intermittent power delivery, arcing, and premature brush wear. Weak or broken springs directly impact motor reliability.
Q: What electric lift truck brands use the BR 27793-011 brush spring set?
A: The BR 27793-011 is compatible with electric lift trucks from major OEM manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, and similar brands. Verify your specific equipment model before ordering to ensure correct fitment.
Q: How do I know if the brush springs are worn or broken?
A: Signs of worn or broken brush springs include reduced motor power, intermittent operation, excessive sparking at the brush contacts, visible brush arcing, motor chatter or vibration, or inconsistent lift performance. If brushes are worn or springs are damaged, replace the spring set to restore proper contact pressure.
Q: Should the BR 27793-011 brush spring set be replaced with brush sets?
A: Yes. When replacing carbon brushes, inspect and replace the spring set as well. Weak or aged springs may not provide adequate contact pressure for new brushes, reducing performance and causing premature wear. Replace both components together for optimal motor operation.
