ProTeam 100173 Carbon Brush Set for 400 Hz Motor (Ametek 116311)
Carbon motor brushes are the scheduled wear item inside every commercial vacuum motor - when they wear down, the motor sparks, loses power, cuts out intermittently, and finally stops. The ProTeam 100173 is the genuine carbon brush set for ProTeam 400 Hz motors, matched to the Ametek 116311 motor used in ProTeam aviation vacuums such as the ProVac AviationVac. Replacing the brushes on schedule is the difference between a quick bench service and a full motor replacement.

- Facility teams reviving a motor that runs weak or sparks heavily at the vents - classic end-of-brush symptoms.

Frequently Asked Questions
How do I know the motor brushes are worn?
Weak suction with a clean filter path, heavy sparking visible through the motor vents, a burning smell, or a motor that stops and restarts when bumped are all classic worn-brush symptoms.
Which machines use the 100173 brush set?
It is ProTeam's brush set for the 400 Hz motor platform used in aviation vacuums like the AviationVac, matched to the Ametek 116311 motor. ProTeam builds several brush sets for different motors - 60 Hz machines like the QuietPro BP and LineVacer use different part numbers - so verify your motor number before ordering.
Can I replace just one brush?
No - always replace brushes as a set. The two brushes wear together, and mixing a new brush with a worn one causes uneven commutator contact and rapid wear.
Is brush replacement worth it versus a new motor?
Yes, when done before the brushes wear to the leads. A brush set costs a fraction of a motor and takes minutes on the bench. If the commutator is already scored or burned, budget for a motor instead.
