This is an Ametek Vacuum Motor for your Fasco models 851DM, 852SVDM and Fasco 8525VDM, 120 volt.
This vacuum uses 2 motors. You may want to replace both motors at the same time as Ametek motors are designed to operate up to 600 hours before they need replacing. If one motor has failed the other will most likely fail shortly there after. It is much easier to replace them both now and save the time and effort.
It is suggested you replace the motor gasket part #MO512.
Protect your motors from dust and dirt by using a motor filter. This prolongs the life of your motor and is a must for all motors. See our part #MO553.
Uses motor brushes part #MO504. |
