Frequently Asked Questions
Q: What is the KO 27693 brush used for in electric lift trucks?
A: The KO 27693 is a carbon brush assembly for electric motors in lift trucks. Brushes conduct current from the stationary commutator to the rotating armature, enabling motor operation.
Q: Which electric lift truck brands are compatible with KO 27693?
A: The KO 27693 is designed for Komatsu electric lift trucks and similar equipment with compatible motor specifications. Verify motor part number and brush pocket dimensions before ordering.
Q: What material is the KO 27693 brush made from?
A: The KO 27693 uses carbon or graphite material for electrical conductivity and low friction against the commutator. This composition balances current delivery with minimal wear.
Q: How do I know the KO 27693 brush needs replacement?
A: Replace brushes if the motor loses power, if sparking occurs at the commutator, or if brushes are worn to the wear limit line marked on the assembly. Worn brushes cannot maintain proper contact.
Q: What is the typical lifespan of the KO 27693 brush?
A: Brush life ranges from 2 to 4 years depending on motor duty cycle and load. Continuous heavy lifting and high-current draw accelerate brush wear.
