The Multiquip 501917 Drive Pinion is a genuine OEM component designed for MQ Mixers, ensuring an exact fit within the drum drive system. Sourced directly from Multiquip, this part meets the original design specifications for the MC44S and related MQ Mixer models. Keeping the drivetrain in proper working order starts with using the correct OEM pinion — and the 501917 delivers just that.
Key Features
- Genuine OEM Gear Geometry — Machined to original tooth profile and pitch specifications, ensuring correct mesh with mating gear components in the drive assembly.
- Direct Drivetrain Replacement — Engineered to install into the existing drive system of MQ Mixer models without modification to the gear housing or shaft.
- Compatible with MQ Mixer Models — Verified fitment for the MC44S and the broader MQ Mixers product family.
- Sustained Drum Rotation Performance — A properly functioning drive pinion transfers power efficiently to the drum gear ring; a worn or damaged pinion causes slippage, uneven rotation, or complete drum failure.
- Durable Construction — Built from materials selected to handle the continuous rotational load and torque demands of mixer drum operation across extended job cycles.
The drive pinion is a core gear component in the concrete mixer's drum drive system. It meshes directly with the ring gear on the drum, transferring rotational power from the engine or motor to keep the drum turning and the mix in motion. When the pinion wears down or fails, the drum loses drive, resulting in poor mixing, erratic rotation, or a completely stalled drum — bringing your pour to a halt. Replacing a worn pinion promptly with the correct OEM part restores full drum function and protects the surrounding gear components from accelerated wear.
