NICE / APOLLO 71020045, BRUSH SET FOR 3500 (2 BRUSHES)
The Nice Apollo 71020045 brush set is a service part for the motor used in select Apollo Vanguard 3500 / 3501 style gate operator applications, especially listings that reference 3500 Telco or 3500ETL brush replacement. Motor brushes are wear parts that maintain electrical contact with the motor commutator. Over time, they can wear down, chip, lose spring pressure, or become contaminated. Replacing brushes can restore proper contact when the motor and commutator are still serviceable, but brushes are not a cure for a burned motor, damaged armature, seized gearbox, bad battery, or misdiagnosed control issue. Before installing new brushes, inspect the brush holders, commutator surface, wiring, and mechanical load on the gate.

Technician Note
If brushes wore out quickly, look for overloading, gate binding, weak batteries, or motor damage. New brushes should not be used to mask a failing motor or unsafe gate condition.
Before Ordering
- Confirm the operator and motor style
- Verify the old brushes match the replacement set
- Inspect commutator condition
- Check for mechanical binding before blaming the motor
- Confirm batteries, wiring, and control output are healthy
Professional Advisory
Disconnect power and battery before motor service. If the motor area shows burned wiring, arcing, or severe corrosion, have the operator inspected by a qualified technician.
Product Questions and Answers
What operator does the 71020045 brush set fit?
