Frequently Asked Questions
Q: What is the CL 4148070 brush spring and what is its function?
A: The CL 4148070 is a spring that maintains brush contact pressure against the commutator in the motor or traction unit of a Clark electric lift truck. This spring ensures consistent electrical contact and brush wear pattern, which is critical for proper motor operation and motor longevity.
Q: What motor or traction components does the CL 4148070 brush spring fit?
A: The CL 4148070 is a Clark OEM part designed for brush spring assemblies in Clark electric lift truck motors. To confirm compatibility with your specific truck model, provide your truck model number and serial range. This spring fits both traction and lift motors in Clark material handling equipment.
Q: How does brush spring tension affect motor performance and brush lifespan?
A: Brush spring tension maintains proper contact pressure between brush and commutator. Correct tension ensures uniform brush wear and efficient commutation. Excessive tension accelerates brush wear and motor heating, while insufficient tension creates arcing and poor electrical contact, leading to commutator damage and motor failure.
Q: What material is the CL 4148070 brush spring made from?
A: The CL 4148070 is manufactured from spring steel designed to maintain consistent tension and resist fatigue over extended use. The spring material is selected for its ability to withstand repeated compression and extension cycles without permanent deformation or loss of tension.
Q: When should I replace the CL 4148070 brush spring?
A: Replace the CL 4148070 when you observe signs of spring fatigue or loss of tension, such as erratic motor performance, visible brush chatter, uneven brush wear patterns, or when replacing motor brushes. Always install new brush springs as part of routine motor brush replacement to ensure optimal brush contact.
