Multiquip 29064-354 Main Shaft Square M40 Hydraulic P&M Mixer

The Multiquip 29064-354 is a genuine OEM Main Shaft Square M40 Hydraulic P&M Mixer component designed for the M40HYD hydraulic plaster and mortar mixer. Sourced directly from Multiquip, this shaft is manufactured to the exact tolerances required to keep your mixer operating at full capacity. It is a direct replacement for the original part on M40HYD equipment, so installation aligns with the existing drivetrain without rework. When you need a critical structural component like this one, genuine OEM is the right call.

Key Features

• Genuine OEM Shaft Integrity — Machined to the original dimensional spec, ensuring the square profile engages the mixing drum drive without slop or wear-accelerating misalignment.
• Direct Drivetrain Replacement — Designed to drop into the M40HYD hydraulic mixer's drive assembly, matching the original shaft geometry and connection points exactly.
• M40HYD Fitment Confirmed — Engineered specifically for the Multiquip M40HYD hydraulic plaster and mortar mixer; verify your model before ordering.
• Sustained Mixing Output — A sound main shaft transfers hydraulic power cleanly to the drum, preventing torque loss, erratic rotation, and premature wear on surrounding drivetrain components.
• Hydraulic Drive Compatibility — Built to handle the load demands of a hydraulically driven mixing system, where shaft deflection or profile wear would compromise the entire drive interface.

The main shaft is the central rotating member that transfers power from the hydraulic drive system into the mixing drum of the M40HYD plaster and mortar mixer. Its square profile locks the drum or drive coupling in place, preventing slippage under the high torque loads that mixing dense mortar or plaster generates. When this shaft wears, becomes bent, or develops play in its profile, the mixer will lose torque transfer efficiency, produce inconsistent drum rotation, and can accelerate damage to bearings and seals throughout the drivetrain.
