Product details
Ametek Lamb builds this ball-bearing motor in the 5.7-inch frame for 120-volt service as part 119997-41, a two-stage thru-flow motor from its Advantek line. Ametek lists its input power at 1425 watts and its replacement brush kit as 8505936-50.
This item is also catalogued under the older number 119997-00, and the two are related but not identical. Ametek catalogs 119997-00 as inactive and replaced by 119997-41, and lists what separates them: 119997-00 has no leads and a terminal board only on a small shaft, while 119997-41 ships with leads and amp terminals on a large shaft. If you are replacing a 119997-00, expect the shaft size and the electrical termination to differ, and check both against the motor coming out.
Because it is a thru-flow design, the intake air travels directly across the windings on its way out of the machine, which is standard for household upright and canister vacuums but not for central vacuum power units, which use a sealed bypass motor instead. That cooling path only works when air is actually moving, so a full bag, a clogged filter, or a pinched hose leaves the motor running hotter than it should on every use, not just cutting suction at the floor.
Wear shows up as suction that stays weak even with a fresh bag, a bearing sound that shifts from a quiet hum toward a grind, a motor that hesitates before it spins up, or a scorched smell after a few minutes of running. Since this frame size and voltage combination is used across several household machines rather than one specific model, confirm fit against the motor being removed rather than by machine name.
