Behind Fan Washer — Ametek / TEK Motor (A732-9305 / A733-3300)

The Behind Fan Washer (part# A732-9305 for Ametek/Direct-Air motors, or A733-3300 for TEK motors) is a genuine Tacony OEM washer that sits behind the cooling fan on the motor shaft of CleanMax ZM-series uprights. Because these vacuums shipped with two different motor brands, choose the washer that matches your motor — the two are not the same part.

The washer spaces and seats the fan correctly on the motor shaft so the fan runs true behind the fan nut. The correct thickness and diameter differ between the Ametek/Direct-Air motor and the TEK motor, which is why Tacony assigns them separate part numbers — A732-9305 for Ametek and A733-3300 for TEK. Select your motor type above and the matching part number and price are applied.

Replace the behind-fan washer whenever you have the fan assembly apart for a fan, bearing, or motor service, or if the existing washer is deformed, corroded, or missing — running without the correct washer can let the fan sit out of position and vibrate.

Both washers are genuine Tacony parts machined to the original specification so the fan and fan nut torque down correctly. If you are unsure which motor your machine has, call us at 763-535-0770 and we will help you identify it.
