Ingersoll Rand 47674732001 39218193 Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47674732001 39218193 Preventive Maintenance Kit combination is associated with scheduled compressor service and motor-bearing lubrication. 47674732001 is identified as a 4,000-hour preventive-maintenance reference for the R90–110 platform, while 39218193 is the Ingersoll Rand motor-grease reference.

Electric-motor bearings operate continuously under mechanical load and depend on appropriate lubrication to control friction, wear, and temperature. Because bearing lubrication directly affects motor reliability, grease selection should be treated as an equipment-specific maintenance requirement rather than a generic shop-consumable choice.

The 39218193 reference has clear product identification. Ingersoll Rand's spare-parts listing describes it as Motor Grease, while applicable compressor documentation specifies Mobilith SHC 220 (39218193) for 60 Hz motors.

The 47674732001 reference provides the scheduled-maintenance context. It belongs to the 4,000-hour preventive-maintenance family for R90–110 equipment, alongside other consumable and service components used during the defined maintenance event.

The most important consideration when using 39218193 is compatibility with the motor's existing grease. Ingersoll Rand documentation states that alternative greases can shorten motor life because of incompatibility and directs technicians to use the grease specified on the motor's special grease-information nameplate when one is present.

For motors without a grease nameplate, the applicable Ingersoll Rand documentation identifies Chevron Black Pearl #2 (39204292) as the preferred alternative and Chevron SRI 2 (39161641) as another specified option for the documented application. 50 Hz motors may instead require Esso Unirex N3 (92844729). These differences show why 39218193 should not be assumed to be universal across all motor configurations.

Correct grease quantity is equally important. Ingersoll Rand warns that over-greasing can cause bearing and motor failure and emphasizes preventing dirt and contaminants from entering the bearing during lubrication. The required grease quantity should therefore be taken from the motor-specific documentation rather than estimated.

During service, the grease fitting and surrounding area should be cleaned before applying new lubricant. Dirt entering the bearing can undermine the benefit of otherwise correct lubrication and may accelerate wear.

Maintenance personnel should also avoid treating a grease number as sufficient evidence of suitability. Motor frame, shaft-bearing arrangement, operating frequency, speed, temperature, and lubrication system can all influence the appropriate grease and quantity.

The distinction between motor grease and compressor lubricant is important for purchasing teams. 39218193 is intended for applicable motor-bearing lubrication; it is not an air-end oil, coolant filter, separator, or other compressor-fluid component.

The 47674732001 maintenance reference should likewise be kept separate from the individual grease reference in service records. The kit number identifies the scheduled maintenance event, while 39218193 identifies one particular consumable. This improves traceability when purchasing individual components outside a complete kit.

Ingersoll Rand's current parts site lists 39218193 as a genuine spare-part grease reference, while broader parts catalogs describe it as high-temperature grease. This supports its identification as a dedicated maintenance lubricant rather than a general-purpose grease.

The same maintenance principle applies when equipment has been stored. Ingersoll Rand documentation describes specific stored-motor bearing maintenance practices, including rotating the motor at intervals for long-term storage. Storage-related lubrication should therefore follow the applicable motor procedure rather than simply adding grease based on elapsed time.

Exact package quantity, grease container size, formulation details, kit dimensions, and kit weight for every 47674732001 revision were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and maintenance professionals, 47674732001 and 39218193 provide a useful reference for scheduled R90–110 maintenance and motor-bearing lubrication. Correct grease selection, controlled quantity, contamination prevention, and adherence to motor-specific instructions can help support dependable motor and compressor operation.
