Introduction
The Ingersoll Rand 47588563001 / 38034914 Motor Grease Maintenance Kit combines a scheduled preventive-maintenance reference with a dedicated motor-bearing lubricant.
47588563001 is listed as an 8,000-hour preventive maintenance kit for water-cooled compressors and forms part of a wider Ingersoll Rand maintenance-kit family covering different operating-hour intervals and equipment configurations.
The independently documented 38034914 is a motor-bearing grease. Parts records describe it as “GREASE, 13.7 OZ. TUBE, MOTOR BRG. POLLYREX EM,” while other compressor-parts listings identify it as Ingersoll Rand motor-bearing grease.
Unlike compressor oil, motor-bearing grease remains within the bearing lubrication system. Its purpose is to provide the lubrication film required at the rolling-element bearing interface while helping control friction, wear, and operating temperature.
38034914 has also appeared in Ingersoll Rand recommended-parts documentation for applicable UP5 and UP6 compressor configurations. This establishes its role as a service lubricant for compatible motor-bearing applications, although it does not establish universal compatibility across every Ingersoll Rand compressor.
The identification of Mobil Polyrex EM is particularly useful when distinguishing 38034914 from other Ingersoll Rand grease references. Ingersoll Rand's lubricant range contains multiple grease products for different purposes, so the part number should be verified rather than selecting a grease based only on its general category.
Available parts information identifies the package as a 13.7 oz tube. This is the nominal package content and should not be confused with the shipping weight or the amount required for an individual motor-bearing service operation.
Motor-bearing lubrication should be performed according to the specific motor and compressor service procedure. Excessive grease can be just as undesirable as insufficient lubrication because over-greasing can increase bearing temperature and interfere with normal bearing operation.
The correct lubrication quantity and interval can vary according to bearing size, motor construction, operating speed, and service conditions. For this reason, the 8,000-hour maintenance designation associated with 47588563001 should not automatically be interpreted as the individual grease-application interval for 38034914.
During servicing, technicians should inspect the bearing area for abnormal noise, temperature, vibration, grease leakage, discoloration, or other evidence of lubrication problems. Any unusual condition should be investigated rather than corrected solely by adding lubricant.
The supplied pair is treated as one product listing as requested. Public records independently establish 47588563001 as the 8,000-hour water-cooled preventive-maintenance kit and 38034914 as motor-bearing grease. The available documentation does not independently establish that 38034914 is the complete bill of materials contained in 47588563001.
