What motors it replaces: Only replaces motor 117549-12.

When to replace: The signs that a 117549-12 Lamb motor needs to be replaced include: mini breaker popping, electrical smell, excessive blue sparks seen from motor top, you only hear a click, motor shuts down on its own but works later, or its life of 900-1,200 hours has been used up. (If you don't hear a click, then your relay most likely needs to be replaced and your motor may be fine). Five percent of the time, the minibreaker will go bad as well as the motor. If this happens, replace the motor and then evaluate the mini breaker.

How to replace: It is not difficult to replace the 117549-12 Ametek Motor. There are three bolts and a couple of wires. All of our customers are amazed at how easy it is. NOTE: There is no core trade-in. Used motors are thrown away. Click here to read and print out our step-by-step motor replacement instructions. Note that if the unit bolts into metal brackets then the ground wire can be snipped. If plastic then attach the ground wire to the ground from the power cord or anywhere to metal on the unit.

Replacing motor brushes: The Lamb 117549-12 vacuum motor has carbon motor brushes that can be replaced. This should be done before a motor is "on its last legs."

Could not have been easier to install. No instructions necessary, really. I just took snapshots with my digital camera before I removed the old motor and plopped this new one back in. Badda bing badda boom. Saved myself over $500 in service/install fees and I am once again my wife's hero. Thanks!

Yes, 5 stars for this motor. The one it's replacing had 9 years of serious use. It didn't owe me anything more. This newer motor seems a bit quieter as explained in the technical information. I'm happy.
