These motors are the exact motors that came in Rheem/Ruud Furnaces originally. Bear in mind, if your motor has been changed it may not bear the Rheem/Ruud part number that it once did.
Look at the motor or your documentation that came with your furnace and find the number starting with a "51" Example: 51-27210-01

Also order the matching run capacitor for the motor if it is required. If not required you will find "n.a." in the capacitor column. Capacitor chart is at bottom of this page.

All motors below have their rotation as viewed from the wire leads end of the motor.
All motors listed have open enclosures and are meant for indoor use only (not weatherproof).

Mounting Codes:
BB: Belly band mount. Mount goes around the motor itself.
TB: Thru Bolts mount. Mount is attached to the studs at the end of the motor.
SS: Shell Screws mount. Mount is attached by means of screw holes in casing of motor

NOTE: 51-27210-02 and 51-27210-03 comes from the factory to you. No tracking number will be available on these motors.
