The M20050 Compact Air Compressor Bushing Installer is a precision-machined service tool designed specifically for installing Cummins compact air compressor bushings, including those associated with 147610-type bushings.
This tool is engineered to provide controlled, centered installation of bushings into the air compressor housing or accessory drive interface—critical for maintaining shaft alignment and ensuring proper compressor operation.
Compact air compressor bushings operate under continuous rotational load and must be installed:
- Perfectly square to the bore
- To the correct depth
- Without damaging the bushing surface or housing
Improper installation methods—such as hammering or using universal drivers—can lead to:
- Bushing distortion
- Misalignment of the compressor shaft
- Premature wear or seizure
- Oil leakage or reduced compressor efficiency
The M20050 eliminates these risks by using a dedicated driver profile matched to the bushing geometry, distributing force evenly across the bushing face during installation. This ensures a smooth press-fit while preserving both the housing bore and the bushing integrity.
Its compact, application-specific design allows technicians to perform installation in confined areas typical of air compressor mounting locations, without removing additional components.
Constructed from high-strength steel, the M20050 is built for repeated use in heavy-duty diesel environments, making it an essential tool for compressor service and accessory drive maintenance.
Key Features & Benefits

Typical Applications
- Air compressor bushing installation (Cummins compact compressors)
- Accessory drive compressor service
- Compressor rebuild and overhaul procedures
- Preventative maintenance on air brake compressor systems
- Heavy-duty truck and industrial diesel applications
Why It Matters
Air compressor bushings are critical to maintaining shaft stability and rotational alignment. Improper installation can result in:
- Rapid bushing wear
- Compressor inefficiency
- Shaft scoring or failure
- Increased maintenance costs
Because these bushings support components tied directly to air brake systems and auxiliary functions, reliability is essential.
The M20050 ensures repeatable, precision installation, allowing technicians to:
- Install bushings correctly the first time
- Avoid costly rework
- Maintain long-term compressor performance
