Product details
Part 33508 is a replacement carbon brush for the Ametek Lamb 116-330 motor, a 220-volt unit used in central vacuum power units.
Carbon brushes wear down as a normal part of running a motor, and the wear is progressive rather than sudden. Sparking visible at the motor, a burning smell, suction that comes and goes, or power that cuts out and then returns are the signs that the brushes have worn short enough to lose contact, and checking them before they fail completely avoids damage to the commutator underneath.
- Part: 33508
- Fits: Ametek Lamb 116-330 motor
- Voltage: 220
- Function: carbon brush, motor wear part
- Tip: let the brush spring seat fully before closing the motor back up
Replace both brushes together even if only one looks worn, since they wear at close to the same rate and a mismatched pair puts uneven load on the commutator. Brushes are held against the commutator by a small spring, and a brush that has worn down to a stub can jam in its holder rather than riding smoothly, which is what produces the intermittent sparking many owners notice before the motor finally stops turning altogether.
Unplug the unit before opening the motor housing, and note how the old brush and its spring sit before removing them so the replacement goes back in the same orientation. Ships to you in 2-5 business days.
