The Multiquip W1280800466 Robin Engine 8HP EY-28 is a genuine OEM engine assembly designed for Essick and Whiteman plaster and mortar mixer models including EM-700S, EM-700P, EM-900S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P. As a direct Multiquip OEM component, W1280800466 delivers the correct power output and dimensional fit required by these mixer platforms. This engine is sourced straight from the Multiquip parts network, ensuring it meets the same specifications as the original unit your machine was built with. Confirm your model code before ordering to ensure correct application.

Key Features

• Genuine OEM Engine Assembly — Sourced directly from Multiquip, this Robin EY-28 unit matches the original engine specification for output, mounting pattern, and shaft configuration.
• 8HP Robin EY-28 Power Plant — Delivers the rated 8 horsepower output that Essick and Whiteman mixers in this class require to drive drum rotation under load.
• Broad Mixer Compatibility — Fits EM-700S, EM-700P, EM-900S, EM-900P, WM-700S, WM-700P, WM-900S, and WM-900P mixer models.
• Drop-In Engine Replacement — Designed to mount directly to the existing engine deck and drivetrain interface on compatible Essick and Whiteman mixer frames.
• Sustained Mixing Performance — A properly functioning engine maintains consistent drum speed and torque; a worn or failing engine causes uneven mixing, stalling under load, and extended batch times.

The Robin EY-28 is an air-cooled, single-cylinder gasoline engine used as the primary power source on Essick and Whiteman plaster and mortar mixers. It drives the mixer drum through the machine's gear or belt drive system, providing the torque needed to turn heavy mortar, stucco, or plaster mixes consistently. When this engine loses compression, develops fuel delivery issues, or fails entirely, the mixer cannot operate — making a like-for-like OEM replacement the most straightforward path back to full production capacity.
