Braun Multimix maintain gearing

Introduction

Symptom: the Multimix is running fine without load, it can easily be stopped by hand and following a gentle squeaking is noticeable.

Cause is most likely a broken sprocket on the motor shaft.

To repair either a new set of wheels can be installed or the main sprocket can be tried to be glued

    • Check gears and replace if needed.

    • In my case the sprocket on the motor shaft was broken along a tooth. Under load it lost contact and the motor could turn without the gears moving. I tried fixing it by glueing with some 2K epoxy.
