The Multiquip 3351 Driven Pinion Gear is a genuine OEM component designed for Essick and Whiteman plaster and mortar mixer models including the EM-700P, EM-700S, EM-900P, EM-900S, WM-700P, WM-700S, WM-900P, and WM-900S series. Sourced directly from Multiquip, this driven pinion gear meets the exact tolerances and material specifications of the original part. It installs as a direct replacement within the mixer's gear drive assembly, restoring proper power transfer to the drum without additional machining or fitting. If your mixer is showing signs of gear slippage, grinding, or reduced drum torque, the part is the correct OEM solution to get your equipment back in service.
Key Features
- Gear-Grade Material Integrity — Manufactured to OEM hardness and tooth profile specifications, ensuring consistent mesh and load capacity within the drive train.
- Direct Drive Assembly Fit — Engineered to seat correctly within the gear housing of Essick and Whiteman mixer models, aligning with the existing drive components without shimming or modification.
- Broad Mixer Series Coverage — Compatible with EM-700P, EM-700S, EM-900P, EM-900S, WM-700P, WM-700S, WM-900P, and WM-900S plaster and mortar mixers.
- Restored Drum Torque Output — A properly functioning driven pinion gear transfers rotational force efficiently to the drum; a worn or chipped gear causes slippage, uneven mixing, and accelerated wear on adjacent components.
- Genuine OEM Part — Supplied by Multiquip under part number 3351, ensuring you receive the exact replacement component — not a generic substitute — for a mixer that handles demanding mortar and plaster applications.
The driven pinion gear is a core element of the mixer's gear reduction system, responsible for transmitting power from the drive shaft to the drum. It meshes with the drive gear to step down speed and multiply torque, giving the drum the rotational force needed to turn heavy mortar and plaster loads. When the pinion gear wears, chips, or loses tooth contact, the drum may turn inconsistently or stall under load, compromising mix quality and placing additional strain on the motor and drive assembly. Replacing it promptly with the correct OEM part maintains the efficiency and longevity of the entire drivetrain.
