The Multiquip 508312 Drive Pulley 5.5 HP is a genuine OEM component designed for MC64P/S MQ Mixer equipment. Sourced directly from Multiquip, this pulley is manufactured to the same specifications as the original, ensuring correct belt alignment and power transfer on your mixer. It is a direct-fit replacement for MC64P/S models, verified against Multiquip's OEM parts catalog. Keep your concrete mixer running at full capacity with a part built to last in demanding jobsite conditions.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original pulley dimensions and groove profile, ensuring correct belt engagement and load transfer specific to the 5.5 HP drive system.
- Direct-Fit Replacement — Engineered to install in the same position as the original pulley with correct bore and keyway alignment, eliminating guesswork during installation.
- Confirmed MC64P/S Fitment — Verified OEM fitment for Multiquip MC64P/S concrete mixers, so you can order with confidence.
- Consistent Power Delivery — A properly functioning drive pulley maintains correct belt tension and speed ratio, keeping drum rotation smooth and consistent throughout the mix cycle.
- Durable Under Continuous Load — Built to withstand the repetitive torque and vibration demands of concrete mixer operation, resisting wear that leads to belt slippage or premature failure.
The drive pulley transfers engine power to the drum drive belt, converting rotational output from the 5.5 HP engine into the drum movement needed to mix concrete. It works in tandem with the drive belt to maintain a consistent drum speed — if the pulley wears, cracks, or develops groove damage, belt slippage occurs, resulting in uneven mixing or a complete loss of drum rotation. Replacing a worn drive pulley with a genuine OEM Multiquip 508312 restores proper power transfer and protects the belt from accelerated wear.
