Brush Spring Set
Frequently Asked Questions
Q: What is the CU 112446 brush spring set used for?
A: The CU 112446 is a brush spring set for electric motor assemblies in lift trucks. Brush springs maintain contact pressure between carbon brushes and the commutator, enabling proper electrical current flow and motor performance.
Q: Which lift truck motors are compatible with the CU 112446 brush spring set?
A: The CU 112446 fits traction and pump motors in electric lift trucks from common OEM manufacturers. Verify the motor model and brush assembly configuration matches your equipment before ordering.
Q: How do I know when the CU 112446 brush springs need replacement?
A: Replace brush springs when brushes wear to the wear limit, contact pressure weakens, or the motor experiences intermittent power loss, arcing, or poor acceleration. Weak springs reduce brush contact and degrade motor efficiency.
Q: What is the typical lifespan of brush springs in electric motors?
A: Brush spring lifespan depends on operating hours, duty cycle, and commutator condition. Most springs last 2000 to 5000 operating hours. High-duty applications may require more frequent replacement. Monitor brush wear and spring tension during brush replacement intervals.
Q: Why is proper brush spring tension important?
A: Correct spring tension ensures steady contact pressure between brushes and the commutator. Weak springs cause poor electrical contact, sparking, and uneven brush wear. Excessive tension accelerates brush wear. The CU 112446 provides calibrated spring force for proper motor operation.
