The Multiquip 513868 Pinion Gear is a genuine OEM component designed for Essick and Whiteman plaster and mortar mixer models, including the EM70P/S, EM90P/S, WM63E, WM63H5, WM63H8, WM70S/P, WM90S/P, and their LF-suffix variants. Sourced directly from Multiquip, this pinion gear matches the exact tooth profile, material spec, and dimensions of the original part. It confirms fitment across the EM70SLF, EM90SLF, WM63SLF, WM70SLF, WM70PLF, WM90SLF, and WM90PLF mixer series, making it a dependable choice for a wide range of Essick and Whiteman mixer applications. Keep part number 513868 on hand to minimize unplanned downtime during mixer service.
Key Features
- Genuine OEM Gear Geometry — Tooth count, pitch, and bore dimensions match the original Multiquip specification exactly, ensuring correct mesh with the mating ring gear.
- Drop-In Drivetrain Fit — Installs directly into the mixer gearbox in place of the worn original, with no machining or shimming required to achieve proper gear engagement.
- Broad Mixer Compatibility — Confirmed fitment across EM70, EM90, WM63, WM70, and WM90 series Essick and Whiteman plaster and mortar mixers.
- Sustained Drum Torque — A correctly meshed pinion gear delivers consistent rotational force to the drum, maintaining steady mixing action under load with mortar, plaster, or stucco mixes.
- OEM-Grade Material Hardness — Manufactured to the same hardness and wear-resistance standards as the original, resisting the surface fatigue and pitting that leads to premature gear failure.
The pinion gear is a small-diameter driven gear that meshes with a larger ring gear to transfer rotational power from the motor or engine to the mixer drum. In a plaster or mortar mixer, it is a critical link in the drivetrain — carrying the torque load needed to turn a full drum of heavy mix material. When a pinion gear wears, chips, or loses tooth contact, the drum slows, stutters, or stops turning altogether, which can cause uneven mixing, drive component damage, and unplanned stoppage mid-batch.
