Atlas Copco 2901195300 – Motor Overhaul Kit GA26+–30

The Atlas Copco 2901195300 (2901-1953-00) Motor Overhaul Kit is a maintenance and repair kit designed for compatible Atlas Copco GA26+–30 rotary screw compressors. Its purpose is to restore the mechanical condition of the compressor motor during a scheduled overhaul or corrective maintenance operation.

Working Process:

The electric motor provides the rotational power required to drive the compressor element. During normal compressor operation, the motor rotates continuously under electrical and mechanical load.

The motor’s rotating shaft and associated components are supported by bearings and protected by sealing elements. As operating hours increase, bearings, seals, bushings and other wear components can gradually deteriorate because of continuous rotation, temperature, vibration, contamination and mechanical loading.

The 2901195300 Motor Overhaul Kit provides replacement components required during motor overhaul. Replacing these wear components restores the mechanical condition of the motor and helps maintain correct shaft support, sealing and rotational performance.

Parts references identify 2901195300 / 2901-1953-00 specifically as “KIT MOTOR OVERHAUL GA26+-30.”

Available import documentation provides additional evidence about the kit contents, describing it as a motor overhaul kit containing components such as seal rings, seals, steel bushings, circlips, roller bearings, metal rings, a rubber ring and a pin. The same documentation identifies the part number as 2901-1953-00 and states its intended use as preventive and corrective motor overhaul.

The bearings support the rotating shaft and reduce friction between moving components. Proper bearing condition is essential for maintaining smooth and stable motor rotation.

The sealing components prevent contaminants from entering the motor assembly and help retain lubricant where required.

The bushings and rings maintain correct component positioning and mechanical clearances.

The circlips and retaining components secure internal parts in their specified positions and prevent unwanted axial movement.

During normal operation, bearing surfaces and sealing components are subjected to heat, vibration, rotational loads and continuous mechanical movement. Eventually, these components can develop wear, excessive clearance, noise, overheating or leakage.

A worn motor bearing may produce abnormal noise or vibration and can increase motor temperature. Excessive bearing wear can also affect shaft alignment and place additional load on the motor and compressor drive system.

Damaged seals may allow lubricant leakage or permit contaminants to enter the assembly. Contamination can accelerate bearing and shaft wear.

A worn bushing or retaining component can increase mechanical clearance and cause unstable shaft movement.

If motor wear is not addressed, the compressor may experience increased vibration, reduced efficiency, overheating, abnormal noise and eventually motor or drive-system failure.

Motor Overhaul Procedure:

Before performing an overhaul, the compressor must be stopped and electrically isolated according to the applicable Atlas Copco safety procedure. The compressor and motor must be completely de-energized and allowed to cool.

The motor should be removed and dismantled according to the applicable service documentation.

The existing bearings, seals, bushings, retaining rings and other applicable wear components should be inspected for wear, corrosion, overheating, deformation and abnormal clearances.

The components supplied in the 2901195300 Motor Overhaul Kit should be used to replace the applicable worn parts.

Bearings must be installed using the correct installation method so that force is applied to the appropriate bearing race. Seals must be installed without damaging their sealing lips.

Bushings, rings, circlips and retaining components must be installed in their correct locations and orientations.

After assembly, the motor shaft should rotate smoothly without excessive resistance, binding or abnormal play.

The motor should then be correctly mounted to the compressor and the drive alignment checked according to the applicable service procedure.

After electrical connections are restored, the compressor should be started and monitored for abnormal vibration, noise, motor temperature, current draw and overall operating behavior.

A properly overhauled motor should provide smooth rotational power to the compressor element while maintaining reliable mechanical support and sealing.

Using the Atlas Copco 2901195300 Motor Overhaul Kit during the appropriate service interval helps restore worn motor components, reduce vibration and mechanical losses, improve reliability and extend the operating life of the compressor drive system.
