Ingersoll Rand 47674733001 39218193 Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47674733001 39218193 Preventive Maintenance Kit provides a defined reference for scheduled service on compatible R90–110 compressor equipment. 47674733001 is identified as a 2,000-hour preventive maintenance kit, while 39218193 is the motor grease associated with the same service configuration.

Motor-bearing lubrication is a small but important part of compressor maintenance. Electric motors operate continuously under load, and their bearings depend on suitable lubrication to limit friction, control wear, and maintain reliable rotating performance. A planned grease-maintenance program can therefore contribute to overall compressor availability.

The 39218193 reference has particularly strong product traceability. Ingersoll Rand's parts site identifies the number as Motor grease, while compressor documentation specifies Mobilith SHC 220 (39218193) for applicable 60 Hz motors. This distinction is important because 39218193 should not be treated as a general-purpose compressor lubricant.

The relationship between the two requested references is also clearly documented. The R90–110 I maintenance listing shows 47674733001 as the 2,000-hour preventive-maintenance package and lists one 39218193 Motor Grease SHC220 as part of that service. The same package includes the primary air filter 23429822, pre-filter 23497001, and coolant filter 23424922.

Correct grease selection is particularly important in electric-motor bearing applications. Lubricating greases are not universally compatible, and changing products without verifying compatibility can cause thickener interaction, separation, loss of lubrication performance, or shortened bearing life.

Ingersoll Rand's motor-maintenance documentation explicitly warns that alternative greases can result in shortened motor life because of grease incompatibility. The same guidance directs technicians to follow the special grease information nameplate on the motor where one is provided. This makes the motor nameplate an important reference alongside the compressor maintenance schedule.

Quantity control is equally important. Over-greasing can create its own problems by increasing bearing temperature or interfering with normal bearing operation. Ingersoll Rand documentation warns that over-greasing can contribute to bearing and motor failure. Maintenance personnel should therefore follow the specified quantity rather than adding grease simply because the bearing appears dry.

The maintenance interval should also be interpreted together with the motor manufacturer's requirements. The 47674733001 reference establishes a 2,000-hour preventive-maintenance package, but the correct lubrication frequency can depend on motor design and operating conditions. Service records should therefore capture both the compressor maintenance interval and the motor-specific lubrication instruction.

Before greasing, the lubricant point should be inspected for contamination, damaged fittings, hardened grease, or evidence of leakage. Keeping dirt and contaminants out of the bearing environment is an explicit maintenance concern in Ingersoll Rand documentation.

The lubrication process should use the designated grease point and follow the applicable motor service procedure. Mixing 39218193 with an unidentified grease remaining in the bearing should be avoided unless compatibility has been established. Where a lubricant change is required, the applicable manufacturer procedure should determine whether old grease needs to be removed or otherwise managed.

The distinction between motor grease and compressor lubricant is also important for procurement. 39218193 is a motor-bearing grease reference, whereas compressor oil and coolant filters serve different parts of the machine. Treating these products as interchangeable maintenance consumables can result in incorrect servicing.

The broader Ingersoll Rand parts catalog also identifies 39218193 as high-temperature grease, supporting its use as a dedicated maintenance consumable rather than a general-purpose shop grease.

For purchasing teams, retaining the exact 39218193 part number helps avoid confusion with other Ingersoll Rand motor-grease references. For example, documentation for certain 50 Hz motors specifies Esso Unirex N3 under part number 92844729, while other applications may specify different greases. This reinforces the need to match the grease with the actual motor specification.

The complete contents of every 47674733001 package revision, grease container size, packaging dimensions, kit weight, and detailed formulation data for 39218193 were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and service professionals, 47674733001 and 39218193 provide a useful reference for scheduled motor-lubrication maintenance. Accurate grease identification, correct quantity, compatibility control, and adherence to motor-specific instructions can help protect bearings and support dependable compressor operation.

Technical Specifications

Ingersoll Rand identifies 39218193 as motor grease, while applicable compressor documentation identifies it as Mobilith SHC 220 for 60 Hz motors.
