5M3102 Brush As — Cat 12E 955H

This is a brush assembly, typically used in electric motors or generators to maintain electrical contact with a rotating component like a commutator or slip ring. Manufactured to meet CAT's quality standards, it ensures consistent electrical conductivity, unlike worn brushes that may cause arcing or intermittent power loss. Operators might notice reduced performance from the associated electrical component, such as a motor running slower, intermittent operation, or the component failing to function entirely.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of worn brushes may be increased sparking or arcing at the commutator or slip rings, accompanied by a decrease in the performance of the electric motor or generator. If left unaddressed, the worn brushes can lead to uneven wear on the commutator, intermittent electrical contact, and eventual failure of the electrical component. This can result in the loss of critical machine functions powered by that component.

Installation Tip

Ensure the power supply to the motor or generator is disconnected before starting work. When installing new brushes, make sure they move freely in their holders and seat properly against the commutator or slip ring.

Service Note

Inspect the commutator or slip rings for damage, contamination, or excessive wear, as this can affect the performance and lifespan of the new brushes.
