Atlas Copco C190 Element Overhaul Kit Replacement – 2906097300

The Atlas Copco 2906097300 is a C190 Compressor Element Overhaul Kit used during major servicing of the compressor element. The kit is intended to replace wear components such as bearings, seals, gaskets and other internal service parts so that the compressor element can be restored to reliable operating condition.

The compressor element is the main rotating assembly that compresses air. During operation, its bearings and sealing components experience continuous mechanical and thermal loads. An overhaul replaces these wear components and helps restore proper rotor support, sealing and smooth operation.

Working Process

1. Air Intake – Atmospheric air enters the compressor element.
2. Compression – The rotating compressor rotors reduce the air volume and increase pressure.
3. Bearing Support – Bearings maintain accurate rotor positioning during rotation.
4. Sealing – Shaft seals and sealing rings prevent unwanted leakage.
5. Continuous Rotation – The element operates continuously under mechanical load.
6. Overhaul – When wear reaches the service limit, the C190 element is dismantled and inspected.
7. Component Replacement – Bearings, seals, gaskets and other specified wear components are replaced using the overhaul kit.
8. Reassembly & Testing – The element is reassembled, aligned and checked before being returned to service.

Main Functions

• Supports complete C190 compressor-element overhaul.
• Replaces worn bearings and sealing components.
• Restores rotor support and alignment.
• Helps reduce internal leakage.
• Supports smooth and reliable compressor operation.
• Helps extend compressor-element service life.
• Reduces the risk of unexpected element failure.

Typical Wear Symptoms

A compressor element requiring overhaul may show:

• Increased bearing noise.
• Excessive vibration.
• Increased operating temperature.
• Oil or air leakage around seals.
• Reduced compressor capacity.
• Increased power consumption.
• Abnormal rotor noise.
• Deterioration of overall compressor performance.

Overhaul Procedure

1. Shut down the compressor according to the applicable Atlas Copco service procedure.
2. Isolate and lock out the electrical supply.
3. Depressurize the compressor completely.
4. Allow the equipment to cool.
5. Remove the compressor element according to the applicable service instructions.
6. Dismantle the C190 element.
7. Inspect rotors, shafts, bearings and sealing surfaces.
8. Remove worn bearings, seals and gaskets.
9. Clean all components and mating surfaces.
10. Install the applicable replacement components from 2906097300.
11. Check rotor clearances and shaft alignment.
12. Reassemble the compressor element.
13. Verify smooth and free rotation.
14. Reinstall the element into the compressor.
15. Reconnect all associated connections.
16. Restart the compressor and monitor temperature, vibration and noise.
17. Check for leakage and verify normal compressor performance.
