Angle Grinder Gear Housing No name TDS125BB compatible with models 7, 8, 9, 16 (MPN YTDS0209)

Replacement gear housing designed for the No name TDS125BB angle grinder series. This gearbox shell combines metal and plastic elements to protect internal gears and bearings, restore correct alignment of drivetrain components and enable safe operation after repair. The part is intended for models listed as compatible with positions 7, 8, 9 and 16 and is used when the original housing is cracked, worn or deformed.

Advantages

The housing provides mechanical protection for gears and bearings while maintaining correct axial and radial alignment of internal components. Its mixed metal and plastic construction balances strength in load-bearing areas with lighter weight where full metal is not required. Using a direct replacement shell helps reduce vibration, prevent ingress of debris and simplify reassembly during maintenance or repair.

Suitable for

• Repairing a No name TDS125BB angle grinder with a damaged gearbox shell
• Replacing a worn housing to restore alignment and reduce vibration
• Maintenance tasks where the original housing has cracks or deformation
• Workshops performing component-level refurbishment of angle grinders

Key specifications

• Compatibility: designed for No name TDS125BB series models noted as positions 7, 8, 9, 16
• Construction: combined metal and plastic shell for strength and reduced weight
• Function: secures and protects gearbox gears and bearings, maintains alignment
• Mounting: accepts original fastening points and interfaces for ease of installation
• Application: intended for use in handheld angle grinder tools

How to use

Disconnect the grinder from power and remove the cutting or grinding disc and guard. Disassemble the outer casing and remove the motor and gear assembly to access the existing gearbox shell. Detach bearings and gears as needed and replace the damaged housing with the new shell, ensuring proper seating of bearings and correct alignment of gears. Refit all internal components using the original fasteners and verify shaft rotation by hand before reassembling the outer casing and reattaching the guard and disc.

Usage recommendations

Use appropriate hand tools and follow safety procedures during disassembly and reassembly. Inspect bearings and gears for wear and replace any worn parts to avoid premature failure. After installation, test the grinder at low load to confirm correct alignment and absence of unusual noise or vibration.
