Installation Guide for Thermomix Gears

Welcome to our official installation guide. Follow these steps to ensure proper installation and extend the lifespan of your Thermomix gears.

1. Cleaning and Preparation

Before installing the new gear, disassemble and thoroughly clean the worm screw and the entire casing.
Ensure no traces of the old grease are left in the mechanism, as it may contain debris from worn gears.
Use hot water and a degreaser, then let everything dry completely.

Place the new gear on the motor shaft without applying any grease beforehand.
Important: The gear must imprint onto the shaft during installation. Applying grease at this stage prevents the gear from forming a proper imprint, which could cause it to crack or break.
Maintain an exact gap of 0.3 mm between the base of the gear and the motor casing. Use a business card or a thin gauge to adjust the spacing.
Why? The gear teeth are inclined. If the gap is incorrect, the teeth will not align properly, leading to excessive friction and premature wear.

Once the gear is correctly mounted on the shaft and the assembly is adjusted, apply a thin layer of PTFE-based grease only to the gear teeth.
Warning: Using non-PTFE grease or failing to use any grease at all may cause rapid wear or malfunction.
Grease should never be applied before mounting the gear on the shaft.

This gear is designed to act as a mechanical fuse, protecting the motor from excessive strain.
If the gear breaks, it indicates abnormal resistance in the mechanism, often caused by improper installation or excessive force.
Premature wear or breakage is not due to a manufacturing defect but rather a problem with adjustment or lubrication.

Mandatory 0.3 mm gap: Ensures perfect alignment of the gears and prevents excessive friction.
PTFE-based grease required: Reduces friction and extends the lifespan of the gears.
Thorough cleaning: Remove all residue from old grease or worn gears.
No grease on the shaft during installation: Ensures the gear forms a proper imprint for secure and precise mounting.
Gear as a fuse: If it breaks, it protects your motor from excessive strain. Repeated breakage indicates a problem with the installation or overall mechanism function.
