CT 1009190

Frequently Asked Questions

Q: What is the purpose of the spring brush set CT 1009190?
A: The CT 1009190 is a spring brush set containing four brushes for Caterpillar electric lift trucks. Spring-loaded brush assemblies maintain consistent pressure against the motor commutator, ensuring stable electrical contact and smooth power delivery during equipment operation.

Q: Is CT 1009190 the same as part numbers 1009190 or CAT1009190?
A: Yes. CT 1009190, 1009190, and CAT1009190 are cross-referenced part numbers for the same spring brush set. When ordering, use any of these identifiers interchangeably; however, always verify the 4-piece brush configuration matches your equipment specification.

Q: What is the lifespan of spring brushes compared to standard carbon brushes?
A: Spring-loaded brushes typically provide service life of 2,000 to 5,000 operating hours before replacement becomes necessary. Actual lifespan varies based on commutator condition, electrical load, ambient temperature, and motor maintenance practices.

Q: Can I use the CT 1009190 spring brush set on Caterpillar hydraulic lift trucks?
A: No. The CT 1009190 is designed exclusively for Caterpillar electric lift trucks with DC motor assemblies. Hydraulic lift trucks do not use electrical brushes or commutators. Verify your equipment is electric-powered before ordering.

Q: How do I check the condition of spring brushes without disassembling the motor?
A: Visual inspection requires motor disassembly. However, performance-based indicators include reduced speed under full load, grinding or sparking sounds from the motor, or excessive power draw. These symptoms suggest brush wear and the need for replacement.
