No name replacement gear wheels for wall grinder THZ600 set of 3 (sizes 26, 27, 28)

Set of three replacement gear wheels compatible with THZ600 wall grinder, sizes 26, 27 and 28. These toothed wheels are intended to replace worn or damaged gears in the grinder’s transmission, restoring correct rotational drive and helping maintain tool performance during repair and maintenance. The set is suitable for professional workshops and DIY use where the original gears require replacement to extend the service life of the THZ600.

Advantages

The set contains three different sizes to match the original transmission stages and enable direct replacement without additional machining. Manufactured to provide accurate tooth engagement, the gears help reduce backlash and ensure steady rotational movement under typical operating loads. Using replacement gears can reduce downtime and avoid the need to replace the entire gearbox assembly, offering a practical option for targeted repairs.

Suitable for

• Repairing THZ600 wall grinders with worn or damaged transmission gears
• Routine maintenance and parts replacement in workshop environments
• DIY servicing of a home or small professional grinder to restore performance

Key specifications

• Set composition: three gear wheels
• Gear sizes (tooth counts): 26, 27, 28
• Compatible with: THZ600 wall grinder transmission

• Typical application: gearbox repair and maintenance

How to use

Before installation, disconnect the grinder from power and follow the manufacturer’s safety instructions for accessing the gearbox. Remove the gearbox cover and extract the worn gear wheels using appropriate tools, noting the original orientation and spacing. Fit the replacement gears of corresponding sizes onto the shafts, ensuring correct mesh with adjacent gears and secure any retaining elements such as circlips or fasteners. Reassemble the gearbox, verify free rotation by hand, and run a short test under no-load conditions to confirm correct engagement and absence of excess play.

Usage recommendations

Inspect mating gears and bearings for wear when replacing gear wheels; replace any additional worn components to prevent accelerated wear. Apply the lubricant recommended for the THZ600 gearbox during reassembly and follow torque specifications for fasteners where provided by the grinder manufacturer.
