Product details

This is a replacement carbon brush for Ametek Lamb 116-276-01 and 116-227-00 motors, part 33326-1. Carbon brushes are the small blocks that ride against the motor's commutator, spring-loaded to keep constant contact as the armature spins, and they are the one part inside a vacuum motor built to wear down on purpose.

As the brush face wears, contact gets inconsistent before it fails outright. Watch for sparking visible through the motor's vent slots, a scratchy or intermittent sound under load, suction that comes and goes rather than staying steady, or a burnt electrical smell after a long run. Any of those point at the brushes before the bearings or the fan.

Confirmed fitment for this brush is the Ametek 116114 and 116146 motors. Motor numbers in this family look much alike at a glance, so match the number stamped on your unit against the two listed here rather than going by frame size or outward appearance. Brushes are a small cost next to a motor, and swapping a set at the first sign of sparking is what keeps a worn brush from scoring the commutator and turning a routine service item into a motor replacement.

  • Part: 33326-1, replacement carbon brush
  • Fits: Ametek 116114, 116146 motors
  • Symptoms of wear: sparking, intermittent power, burning smell
  • Install note: check brush spring tension and the commutator surface while the motor is open
  • Replace as: a matched pair, not one brush at a time
