Frequently Asked Questions
Q: What does the brush set CT 1009186 contain and what is its purpose?
A: The CT 1009186 is a brush set containing four individual brushes designed for electric motor commutators in Caterpillar and Mitsubishi lift trucks. Brushes transfer electrical current to the rotor and wear down over time, requiring periodic replacement to maintain motor performance.
Q: How do I know when brush replacement is necessary for my electric lift truck?
A: Signs of brush wear include reduced motor acceleration, inconsistent power delivery, visible sparking at the motor commutator, or grinding noise from the motor area. Worn brushes typically require replacement based on usage intensity and operational hours.
Q: Which makes and models is the CT 1009186 compatible with?
A: The CT 1009186 brushes are compatible with Caterpillar and Mitsubishi electric lift trucks that use the corresponding motor. Cross-reference your equipment model number with the manufacturer's specification sheet to confirm compatibility before ordering.
Q: What material are these brushes made from and how does that affect performance?
A: These brushes are typically made from carbon-graphite or copper-graphite material compounds selected for electrical conductivity, heat dissipation, and commutator surface compatibility. Material composition affects brush wear rate, current transfer efficiency, and motor longevity.
Q: Should I replace all four brushes at once or only the worn ones?
A: Industry best practice is to replace all brushes in a set simultaneously, even if only one or two show significant wear. This ensures uniform electrical contact across all brush positions and prevents uneven commutator wear that can reduce motor life and performance.
