Product details
Part 116764-13 is a three-stage Ametek Lamb vacuum motor, 5.7 inches across the fan housing, wound for 120 volts, with a peripheral discharge that routes exhaust air around the outside of the motor rather than straight through the center. Ametek catalogs it on the Traditional Lamb ACUSTEK platform, its low-noise discharge option for this family.
Ametek offers the 5.7-inch bypass peripheral motors with either a standard louvered discharge or the low-noise ACUSTEK discharge, and rates the family at sealed vacuums up to 160 inches of water lift and flow rates up to 107 CFM. For this part it lists an input power of 1275 watts, a replacement brush kit of 833392-67, and notes that 116764-13 is the same motor as 116764-00 with bearing protection added.
Three-stage motors trade some raw airflow for higher static pressure, which is why they show up in machines built for deep-pile carpet or long hose runs where the suction needs to hold up rather than just move a lot of air. The discharge style affects noise and airflow path more than it affects how you diagnose a failing unit, since the wear signs are the same as any vacuum motor.
Watch for suction that has dropped and stays down after a bag and filter change, a bearing note that has gone from a smooth hum to a grind or a whine, running that cuts out under load, or a hot, sharp smell after a few minutes of use. Any of those point to the motor rather than something further up the airflow path. Match it against your old motor by frame size, stage count, voltage and discharge style rather than by vacuum brand or model name.
