Product Description
The A000040849 is a steer motor brush set engineered to maintain electrical contact between the motor commutator and external circuit on electric pallet jacks. This carbon-graphite composite brush assembly is essential for smooth steering responsiveness and optimal motor performance.
Replace worn brushes when you notice sluggish steering, increased motor noise, or difficulty turning. Timely brush replacement protects the motor from excessive commutator wear and electrical resistance buildup, extending equipment life and maintaining operator safety in warehouse and dock environments.
Compatible with steer motor assemblies across major electric pallet jack brands including Crown, Toyota, Raymond, and Jungheinrich equipment.

Frequently Asked Questions
Q: What does the A000040849 brush set do?
A: The A000040849 is a steer motor brush set that maintains electrical contact between the motor commutator and the external circuit. Worn brushes reduce steering responsiveness and increase motor resistance.
Q: Which makes are compatible with the A000040849 brush set?
A: This brush set is compatible with steer motors on electric lift trucks from Mitsubishi, Caterpillar, and Unicarriers. Confirm your motor model and voltage before ordering to ensure compatibility.
Q: What are the symptoms of worn steer motor brushes?
A: Worn brushes cause sluggish steering, increased motor noise or sparking, and difficulty turning. The steering motor may feel unresponsive or require more effort than normal. Grinding sounds indicate brush wear.
Q: What material are the A000040849 brushes made from?
A: Steer motor brushes are typically carbon-graphite composite material designed to conduct current while minimizing wear on the commutator. This composition balances electrical conductivity with mechanical durability.
Q: Do worn brushes damage the steer motor?
A: Yes. Continuing to operate with severely worn brushes increases commutator wear and electrical resistance, potentially causing motor failure. Replace brushes promptly when wear symptoms appear to protect the motor.
Q: How can I determine if I need to replace the A000040849 brush set?
A: Inspect the brushes for visible wear, such as shortened length or uneven surfaces. If you experience steering issues like sluggishness or increased motor noise, it may be time to replace the brush set.
