Atlas Copco C190 Element Overhaul Kit Replacement – 2906097300

The Atlas Copco 2906097300 C190 Element Overhaul Kit is a specialized compressor element maintenance and overhaul kit designed to service the C190 compressor element. The kit is used during major maintenance when internal bearings, gaskets, seal washers and other wear components require inspection and replacement.

During compressor operation, the C190 element continuously rotates at high speed to compress air. Bearings support the rotating components and maintain accurate shaft alignment, while gaskets and sealing components help prevent unwanted oil and air leakage. Over time, continuous mechanical loads, temperature and operating hours can cause these components to wear. The 2906097300 element overhaul kit provides replacement service components needed to restore the element assembly to proper operating condition.

Working Process

1. Air Intake – Ambient air enters the compressor through the air-intake system.
2. Compression – The C190 compressor element compresses the incoming air.
3. Rotational Operation – Internal rotating components operate continuously at high speed.
4. Bearing Support – Bearings maintain shaft position and support rotating loads.
5. Sealing – Gaskets and seal washers help maintain proper sealing around the element assembly.
6. Heat and Load Generation – Continuous compression creates mechanical and thermal loads.
7. Component Wear – Bearings and sealing components gradually deteriorate with operating hours.
8. Element Inspection – During major service, the C190 element is removed and inspected.
9. Overhaul – Worn bearings, gaskets and sealing components are replaced using the 2906097300 C190 Element Overhaul Kit.
10. Reassembly – The compressor element is carefully rebuilt according to the applicable Atlas Copco service procedure.
11. Alignment Check – Shaft and bearing alignment are checked before installation.
12. Installation – The overhauled element is installed back into the compressor.
13. Leak Test – Oil and air connections are inspected for leakage.
14. Performance Test – The compressor is restarted and checked for pressure, temperature, vibration and noise.
15. Final Verification – Normal compressor performance is confirmed after the overhaul.

Components Associated with the Kit

Atlas Copco parts documentation lists the following components under the C190 Element Overhaul Kit:

The parts list identifies 2906 0973 00 as the Element Overhaul Kit (C190) and lists these associated sealing components.

Main Functions

• Supports C190 compressor element overhaul.
• Replaces worn sealing components.
• Helps maintain proper element sealing.
• Supports reliable bearing and rotating-element operation.
• Helps reduce the risk of oil and air leakage.
• Helps restore compressor performance after major maintenance.
• Extends the service life of the compressor element.

Typical Reasons for C190 Element Overhaul

The element may require overhaul because of:

• High operating hours.
• Bearing wear.
• Increased vibration.
• Abnormal operating noise.
• Increased discharge temperature.
• Reduced compressor capacity.
• Increased power consumption.
• Oil leakage.
• Deteriorated sealing components.
• General compressor-element wear.

Maintenance / Overhaul Procedure

1. Shut down the compressor using the applicable Atlas Copco service procedure.
2. Isolate and lock out the electrical supply.
3. Fully depressurize the compressor.
4. Allow the compressor to cool.
5. Isolate and drain the relevant oil circuit.
6. Remove the C190 compressor element.
7. Dismantle the element using the approved overhaul procedure.
8. Inspect bearings, shafts, gears and sealing surfaces.
9. Clean the components and mating surfaces.
10. Replace the worn components supplied with 2906097300.
11. Install the new gaskets and seal washers correctly.
12. Verify bearing condition and shaft alignment.
13. Reassemble the C190 element.
14. Check smooth shaft rotation.
15. Reinstall the element into the compressor.
16. Reconnect all applicable oil and air connections.
17. Restore the oil system.
18. Restart the compressor.
19. Check vibration, temperature, pressure and noise.
20. Inspect for oil or air leakage.
21. Confirm normal compressor performance.
