Technical FAQs

1. What is the 47579611001 39218193 configuration used for?

It combines the 47579611001 8,000-hour air-cooled maintenance package with the specified 39218193 motor grease as one complete service configuration.

2. Which compressor platform is associated with 47579611001?

47579611001 is associated with the Ingersoll Rand Sierra 37–75 kW oil-free air-cooled compressor platform.

3. What is 39218193?

39218193 is an Ingersoll Rand motor grease reference identified in applicable documentation as Mobilith SHC 220.

4. What is the function of 39218193?

The grease provides lubrication for applicable electric-motor bearing assemblies, helping reduce friction and wear during normal motor operation.

5. Is 39218193 suitable for every compressor motor?

No. The correct grease depends on the motor's specific lubrication specification, operating frequency, bearing arrangement, and grease information provided on the motor or equipment documentation.

6. Why is grease compatibility important?

Mixing incompatible greases can adversely affect lubricant performance and may contribute to bearing or motor problems, so the specified lubricant should be confirmed before application.

7. What should be checked before applying 39218193?

The technician should verify the motor identification, grease specification, bearing arrangement, lubrication quantity, service interval, and applicable Ingersoll Rand maintenance instructions.

8. What can happen if a motor bearing is over-greased?

Excessive grease can increase bearing temperature, interfere with normal bearing operation, and contribute to premature motor or bearing failure.

9. Should the motor be stopped before lubrication?

Yes. Motor lubrication should be performed using the applicable lockout/tagout and equipment-specific safety procedure, with the motor isolated as required by the maintenance instructions.

10. What should be recorded after completing the lubrication service?

The maintenance record should include the compressor operating hours, service date, grease part number, quantity applied, motor identification, and any abnormal bearing or lubrication conditions observed.
