Multiquip 13228 Dump Cylinder Pin

The Multiquip 13228 Dump Cylinder Pin is a genuine OEM component designed for EM120P Series, EM120S Series, WM120PH, and WM120SH concrete and mortar mixers. As a factory-sourced replacement, this pin is manufactured to the exact dimensions and material specifications required by these Essick and Whiteman mixer models. Whether you are servicing a drum-dumping system that has worn or seized, or completing a full hydraulic cylinder rebuild, the 13228 is the correct part for a direct, like-for-like swap. Sourced through DHS Equipment, you can be confident you are receiving an authentic Multiquip part backed by OEM quality standards.

Key Features

• OEM-Grade Material Strength — Manufactured to Multiquip's hardness and dimensional tolerances, ensuring the pin withstands the shear and load forces generated during repeated drum-dump cycles.
• Drop-In Cylinder Replacement — Engineered to the exact diameter and length of the original dump cylinder pin, allowing straightforward installation without machining or shimming.
• Broad Mixer Compatibility — Fits EM120P Series, EM120S Series, WM120PH, and WM120SH models across both the Essick and Whiteman mixer lines in the Multiquip portfolio.
• Restores Full Dump Cycle Function — A worn or missing cylinder pin causes erratic, incomplete, or uncontrolled drum dumping; replacing it with the correct OEM pin restores smooth, controlled drum rotation.
• Hydraulic System Integrity — Proper pin fit prevents side-loading on the cylinder rod and seals, protecting the surrounding hydraulic components from premature wear.

The dump cylinder pin is the pivot point that connects the hydraulic or mechanical dump cylinder to the mixer drum assembly. When the operator activates the dump function, this pin transfers the force of the cylinder stroke into controlled drum rotation, allowing material to be poured cleanly and safely. A pin that is worn, bent, or missing will cause the cylinder to bind, slip, or apply uneven load to the drum yoke — resulting in sloppy pours, accelerated wear on surrounding hardware, and potential loss of control during the dumping operation.
