Mitutoyo 101169 Post Drop Indicator Back 12.7mm Agd 2

Product Description

The MITUTOYO 101169 is a replacement indicator back designed for post drop dial indicators used in precision measurement applications. This component provides the rear mounting surface of the indicator body and is intended for use with AGD 2 style indicators. At 12.7mm in diameter, it is sized to factory specification. Licensed metrology technicians, tool and die professionals, and precision machining shops install this part when the original back is damaged, worn, or when a specialized mounting configuration is required for a non-standard application. The part ships individually and is a direct OEM-style replacement component.

This indicator back is suited for environments where AGD 2 dial indicators are used in quality control inspection, machining setups, surface plate work, and fixture-based measurement. The replacement is appropriate when the existing back has been damaged during handling or when a special application requires an alternate back configuration. It fits into standard bench, arm, and surface gauge mounting setups that accept AGD 2 indicators.

Key Features

• Designed as a direct replacement back for AGD 2 post drop dial indicators
• Back diameter of 12.7mm for OEM-spec fitment
• Supports special application mounting configurations where the factory back must be swapped
• Sold individually for single-unit service needs
• Lightweight at 0.05 pounds, adding negligible mass to the indicator assembly

Compatibility

Intended for use with AGD 2 style post drop dial indicators. Verify back diameter and indicator series before installation.

Installation Notes

Installation should be performed by a qualified metrology technician or machinist familiar with precision indicator components. Remove the indicator from any mounting arm or fixture before disassembling the indicator body. Use appropriate spanner tools or case wrenches designed for dial indicator service to avoid damaging the bezel, crystal, or internal movement. Avoid applying excessive force during reassembly, as indicator components are manufactured to tight tolerances.
