Ingersoll Rand 47556402001 39218193 Water-Cooled Preventive Maintenance Kit with Modification

Introduction

The Ingersoll Rand 47556402001 39218193 Water-Cooled Preventive Maintenance Kit with Modification combination covers the motor-lubrication portion of the modified 8,000-hour major-service program for R90–110 I compressors. 47556402001 is the overall water-cooled maintenance package with MOD, while 39218193 identifies the Motor Grease SHC220 component.

Electric-motor bearings require suitable lubrication to maintain low friction, control wear, and support reliable continuous operation. In compressor service, motor lubrication is therefore an important part of scheduled maintenance even though it is separate from the compressor's circulating oil system.

The 39218193 reference is clearly identified in the published maintenance data as Motor Grease SHC220. One unit is specified within the R90–110 I 47556402001 package.

The direct relationship between the requested references is clear in the service table. The modified 8,000-hour package includes one 39218193 unit together with the 23429822 air filter, 23424922 coolant filter, 23497001 pre-filter, 23545841 separator, 23531577 minimum-pressure-valve kit, 47552954001 temperature-control kit, 47553881001 modified inlet-valve kit, and 47555464001 water-cooler seal kit.

This confirms that 47556402001 is a comprehensive major-maintenance package rather than a grease-only service. Motor lubrication is performed alongside filtration, separation, pressure control, temperature control, inlet control, and cooling-system maintenance.

The MOD designation is important for procurement but does not mean every component receives a different part number. In the published configuration, 39218193 remains the specified motor grease, while the inlet-valve service component changes from standard 47553880001 to modified 47553881001.

Grease selection should remain motor-specific. A lubricant that appears suitable by viscosity or appearance may still have incompatible thickener chemistry or other formulation differences. Maintenance personnel should therefore follow the motor's own grease requirements and the applicable Ingersoll Rand procedure.

Correct quantity is equally important. Both under-lubrication and over-lubrication can negatively affect bearing performance. The required amount should be taken from the motor-specific documentation rather than estimated.

Before lubrication, the grease fitting and surrounding area should be cleaned so contamination is not introduced into the bearing. The lubrication point should also be inspected for damage, leakage, or other abnormal conditions.

The published parts data shows 39218193 being used in several other Ingersoll Rand preventive-maintenance packages, including R90–110 I 2,000- and 4,000-hour packages and R132–160 I configurations. This broad usage means the part number alone should not be treated as proof that every motor requires the same lubrication interval or quantity.

For maintenance planners, the pair 47556402001 + 39218193 provides useful service traceability. The first number identifies the modified 8,000-hour water-cooled maintenance event, while the second identifies the motor-lubrication consumable.

For purchasing teams, the compressor model, serial number, motor specification, and MOD status should be retained with the part number. This helps prevent confusion between recurring motor-grease requirements and configuration-specific service components.

The grease should not be confused with compressor oil or other fluid-system products. 39218193 belongs to the electric-motor lubrication system, while 23424922, 23545841, and other components in the same kit serve different compressor functions.

Exact grease formulation beyond the published SHC220 identification, container size, package dimensions, kit weight, motor-specific grease quantity, and complete revision-specific application data were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and maintenance professionals, 47556402001 and 39218193 provide a clear reference for motor-bearing lubrication within the modified 8,000-hour water-cooled R90–110 I maintenance program. Correct grease identification, controlled application, and adherence to motor-specific instructions can help support dependable motor and compressor operation.
