Multiquip 802453 Paddle Arm Center - OEM Replacement Part for Hydraulic Plaster Mortar Mixers

The center paddle arm is a critical mixing component in Multiquip hydraulic plaster and mortar mixers, working in conjunction with drum-end and engine-end paddle assemblies to create proper material flow and consistent batch mixing. This cast paddle arm mounts to the central section of the rotating paddle shaft inside the 12-cubic-foot mixing drum, where it must maintain precise clearance from drum side walls for optimal mixing performance.

Proper paddle blade adjustment is essential for mixer operation. The center paddle arm should rotate freely without being too tight against the drum side walls, as incorrect positioning reduces mixing efficiency and accelerates wear on both the paddle and drum surfaces. These mixers use plastic and rubber mixing paddles specifically designed for plaster and mortar applications with batch capacities of 3-1/2 to 4-1/2 bags. The paddle shaft is controlled by the 3-position hydraulic paddle control lever, which activates clockwise rotation during mixing operations.

Regular inspection of paddle arms is recommended as part of routine maintenance, especially after extended use or when mixing abrasive materials. Always clean paddles after each use to prevent material buildup and ensure consistent performance.

Compatible with the following Multiquip mixer models:

• PRO12 / PRO12E51
