The Multiquip 491692 Cotter Pin is a genuine OEM fastener designed for Essick and Whiteman plaster and mortar mixer models, including the EM70, EM90, WM63, WM70, WM90, and PRO20 series. As an authentic Multiquip OEM component, it is manufactured to the exact material and dimensional tolerances required for correct installation and long-term function. This pin fits a wide range of mixer configurations across both the Essick and Whiteman product lines, making it a versatile service item to keep on hand. Sourced directly through authorized Multiquip supply channels, the 491692 is the correct replacement when servicing these mixers.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact hardness and shear specifications required for secure retention in mixer shaft and linkage applications.
- Drop-In Installation — Matches the original pin diameter and leg spread, fitting directly into the existing cotter pin bore without rework.
- Broad Mixer Compatibility — Fits Essick EM70, EM90, EM900SD, and PRO20 models as well as Whiteman WM63, WM70, and WM90 series mixers in steel, plastic drum, Honda, electric, and MPower configurations.
- Secure Fastener Retention — A correctly seated cotter pin keeps clevis pins, axle pins, and other retained fasteners locked in position during mixing operation, preventing component separation under load.
A cotter pin is a split-leg fastener inserted through a drilled hole in a pin or bolt to prevent it from backing out during operation. In plaster and mortar mixers, cotter pins are used to secure clevis connections, drum axle pins, and other mechanical linkages that experience constant vibration and cyclic loading. When a cotter pin fails or goes missing, the retained fastener can work loose, leading to play in the linkage, accelerated wear on surrounding components, or sudden disengagement of a critical joint. Replacing a worn or missing cotter pin with the correct OEM part — in this case Multiquip 491692 — restores the mechanical lock and protects the integrity of the surrounding assembly.
