The Non-Clutch Agitator Pulley with Bearing (part# B012-3900B) is the genuine Tacony OEM drive pulley for the CleanMax CMPS-QDZ Pro Series agitator. The belt wraps this pulley to spin the brushroll, and its integrated bearing lets that end turn smoothly.

This is the non-clutch style pulley — a direct belt-driven pulley with a built-in bearing, so the brushroll turns whenever the belt is driven. If the pulley’s teeth or groove are worn, or its bearing has gone rough, the belt slips, squeals, or the roll stops turning under load.

Replace the pulley when the belt no longer grips it, when the integrated bearing is noisy or notchy, or when the brushroll bogs down and quits spinning while the motor runs. Because the bearing is part of the pulley, replacing this piece renews both at once.

Frequently Asked Questions

What does the B012-3900B agitator pulley do on the CleanMax CMPS-QDZ?

It is the belt-driven pulley on the end of the brushroll; the drive belt wraps it to spin the agitator, and its built-in bearing lets that end turn smoothly.

Is the B012-3900B the clutch or non-clutch pulley?

It is the non-clutch pulley — a direct-drive pulley with an integrated bearing, so the brushroll turns whenever the belt is driven rather than engaging through a clutch.

Does the B012-3900B pulley include the bearing?

Yes — the bearing is integrated into the pulley, so replacing this part renews both the drive pulley and its bearing together.
