Ametek Carbon Brush - Motor...
$9.99
Product details
White-winged and sold one at a time, this carbon brush mechanism, part 33423-12, serves a wide span of Ametek Lamb motors. The brush rides on the commutator and feeds current into the armature, and as it wears down that contact goes intermittent and the motor loses its edge.
The pattern is familiar to anyone who has serviced a Lamb motor: reduced suction, a motor that hesitates on start-up, visible sparking through the vents, and a sharp burning smell after a long run. None of that means the motor is finished. It usually means the brushes are.
It fits Ametek Lamb motor 119678 and its 119678-0 and 119678-00 variants, the 117123 family including 117123-00, -07, -13, -29 and -35, the 117944-00 and the 119709-00. Fit them in pairs so both sides seat evenly against the commutator.
