Behind Fan Washer for Ametek Direct-Air Motor ULW A732-9305

The Behind Fan Washer for Ametek Direct-Air Motor ULW (part# A732-9305) is a genuine Tacony OEM thin washer that sits behind the fan on the Ametek direct-air motor used in ultralight (ULW) cordless vacuums. It is the Ametek-motor version — distinct from the TEK-motor washer (part# A733-3300) — so it must be matched to your motor type.

Compatible Models for the A732-9305 Behind Fan Washer

• CleanMax ULW cordless ultralight vacuums with the Ametek direct-air motor
• Shared across Tacony ULW cordless models using the Ametek motor

This is a genuine Tacony OEM part for ULW cordless vacuums built with the Ametek direct-air motor. If your machine uses the TEK motor, you need washer A733-3300 instead. Call 763-535-0770 and we will confirm which motor your machine has.

What the behind-fan washer does

The behind-fan washer sits between the fan and the motor shaft shoulder on the Ametek direct-air motor, setting the correct spacing so the fan seats squarely, is retained properly, and runs without rubbing. Correct fan position protects both airflow and the motor bearing. It is a thin, precise spacer matched to the Ametek motor’s shaft.

Signs the behind-fan washer needs replacing

Replace the washer if it is deformed, worn, or missing, or if the fan is loose, sits wrong, or rubs when the motor is serviced. Fit a fresh washer any time the fan is removed on an Ametek-motor machine, since it sets critical fan spacing.

Installation and fit

Power down and isolate the battery; motor and fan work is best done by our service staff. When the fan is serviced on an Ametek-motor machine, the new washer is fitted behind the fan in the original position so the fan seats and spaces correctly on the shaft. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony. Browse more CleanMax parts, or learn more at CleanMax.
