The Multiquip 803396 Jackshaft is a genuine OEM component designed for MQ Mixer series equipment. Sourced directly from Multiquip, this jackshaft is manufactured to the exact specifications of the original part, ensuring a proper fit and correct power transfer within your machine. Confirmed fitment includes the MC12PH concrete mixer, making it a straightforward like-for-like replacement when the original shaft has worn or failed.
Key Features
- Genuine OEM Construction: — Machined to original Multiquip tolerances, ensuring correct shaft diameter, keyway alignment, and bearing seat dimensions specific to this mixer drivetrain.
- Direct-Fit Replacement: — Engineered to drop into the existing drivetrain assembly of the MC12PH without modification to mounting points or drive components.
- Confirmed MQ Mixer Compatibility: — Verified fitment for the MC12PH concrete mixer series, so you can order with confidence that this is the correct part for your machine.
- Restores Full Drive Efficiency: — A worn or damaged jackshaft causes slippage, uneven drum rotation, and accelerated wear on pulleys and belts; replacing it restores smooth, consistent power transfer to the drum.
- Long-Term Drivetrain Integrity: — Using the correct OEM shaft protects adjacent components — including bearings, belts, and pulleys — from premature wear caused by dimensional mismatches.
The jackshaft is an intermediate shaft in the mixer's drivetrain that transfers rotational power from the engine to the drum assembly, typically via belts, pulleys, or gears mounted along its length. It acts as a mechanical bridge between the power source and the mixing drum, allowing the engine's output to be stepped down to the correct drum speed. When a jackshaft wears, bends, or develops play in its bearing seats, the result is vibration, uneven drum movement, and increased stress on surrounding drive components — making timely replacement essential to keeping the mixer operating correctly.
