Angle Grinder Gear Housing for TDS125A models (fits variations 7, 8, 9, 12, 17) by No name

Replacement gear housing designed specifically for the angle grinder model TDS125A and compatible with its variations 7, 8, 9, 12 and 17. This gear housing forms the structural enclosure for the gearbox, provides mounting points for internal components and ensures proper alignment and protection of the transmission elements. The spare part is intended for restoring the mechanical integrity of the grinder where the original housing is damaged, cracked or worn.

Advantages

The housing restores correct positioning of bearings, gears and shafts to minimise transmission play and reduce vibration. Manufactured to match the original mounting interfaces, it allows direct replacement without modification of adjacent parts. The casing provides mechanical protection for gearing and contributes to safer operation by enclosing moving parts and limiting ingress of dust and debris into the gearbox area.

Suitable for

• Repairing a TDS125A angle grinder with a cracked or broken gearbox housing
• Replacing a worn housing to reduce gearplay and vibration
• Maintenance or refurbishment of workshop grinders to restore correct gear alignment
• Technical servicing where original housing mounting points need renewal

Key specifications

• Compatibility: Angle grinder model TDS125A and variations 7, 8, 9, 12, 17
• Function: Structural enclosure for gearbox and mounting for internal components
• Material: Durable moulded housing suitable for mechanical load and heat dissipation
• Fit: Designed to match original mounting interfaces and bearing locations
• Protection: Encloses gears to reduce contamination from dust and debris

How to use

Disconnect the grinder from power and remove the disc and guards before beginning work. Disassemble the gearbox area according to the manufacturer’s service procedure, noting the position of bearings, shims and fasteners. Remove the damaged housing and transfer internal components to the replacement housing, ensuring bearings and shafts are seated in their correct locations. Reassemble the gearbox and outer covers, verify that gears rotate freely without binding and restore all safety guards before returning the tool to service.

Usage recommendations

Inspect bearings, seals and fasteners during replacement and renew any worn items to ensure long-term reliable operation. After assembly, run the grinder at no-load speed briefly to check for abnormal noise, vibration or misalignment, then test under light load before normal use.
