A Sanitaire upright is built around a steel body and a metal brush roll that will outlive several motors, which is exactly why a motor swap is usually the smart repair. This 7 amp single-speed motor assembly is the standard replacement for Sanitaire and Eureka commercial uprights rated 6.5 or 7.0 amps, and it arrives with the fan blade and metal belt pulley fitted, so the job is a wiring and mounting operation rather than a rebuild.
Built for
In-house maintenance departments and janitorial contractors who repair their own commercial uprights, plus vacuum shops and schools, hotels and churches keeping a fleet of Sanitaire machines on the floor.

Frequently asked questions
Which vacuums does this motor fit?
Sanitaire and Eureka commercial uprights rated at 6.5 or 7.0 amps, including SC899, SC888, SC887, SC886, SC684, S647, S661, S663, S670 and S677. Send us your model number if you want it confirmed.
Does it come with the fan and pulley?
Yes. The assembly includes the fan blade and the metal belt pulley, and it has two lead wires for installation.
Is 15942-2 the same motor?
Yes. This motor is referenced as 54352-3, 15942-2 and 15942-1 across different parts lists.
Is replacing the motor worth it versus buying a new vacuum?
On a Sanitaire it often is. The steel chassis, brush roll and bag system typically remain serviceable long after a motor wears out, so a motor assembly returns the machine to full performance for a fraction of a new unit.
How do I tell a worn motor from a clogged air path?
Rule out the cheap items first: a full bag, a stretched or broken belt, a blocked hose and a bag that is not sealing. If airflow is clear and the machine still runs weak, loud, or hot, the motor is the likely cause.
