3M 7000119156 Spiral Bevel Gear Set Replacement Part

Product Description

The 3M 7000119156 is a replacement spiral bevel gear set designed to restore proper power transmission in 3M disc sanders, die grinders, and cut-off wheel tools. Bevel gears transfer rotational force between intersecting shafts, and worn or damaged gear sets are a common cause of tool vibration, noise, and loss of drive. This part is an OEM-style replacement intended for technicians and service professionals performing internal tool repairs. Replacing a failed gear set returns the tool to factory-specified operation without requiring full tool replacement.

This gear set is used during bench-level service and repair of 3M pneumatic and electric handheld abrasive tools. Typical install scenarios include repair depot work, in-shop maintenance, and field service where a tech has access to proper disassembly tools. The part is sold individually and is intended for use by personnel familiar with the internal drive components of angle and straight-body grinder-style tools.

Key Features

• Spiral bevel gear geometry for smooth, low-noise power transfer between drive shafts
• OEM replacement part — restores factory drive function in compatible 3M abrasive tools
• Sold as a set for complete gear mesh replacement
• Compatible with disc sanders, die grinders, and cut-off wheel tool platforms

Compatibility

Installation Notes
