Multiquip DM1333 Gear & Shaft SB-4 - OEM Replacement Part for Mix N' Go Concrete Mixers

The Gear & Shaft SB-4 is a critical gearbox component that transfers rotational power from the engine to the drum assembly in Multiquip Mix N' Go portable concrete mixers. This precision-engineered drive component ensures reliable mixing performance for concrete and mortar production on job sites.

The gearbox assembly in Mix N' Go mixers is factory-filled with EP90 gear oil and designed for continuous-duty operation. When gear and shaft components show signs of wear—such as unusual noise during operation, difficulty maintaining drum rotation speed, or vibration in the gearbox—replacement with genuine OEM parts is essential to restore proper function and prevent secondary damage to other drivetrain components.

This part is compatible with the following Multiquip Mix N' Go Mini Concrete Steel Drum Mixer models:

• MC3SE
• MC3SEA

These portable mixers are designed specifically for concrete and mortar mixing applications and feature Briggs & Stratton 4-stroke gasoline engines. Regular inspection of gearbox components helps maintain optimal mixing performance and extends equipment service life.
