Ingersoll Rand 47555208001 39218193 Air-Cooled Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47555208001 39218193 Air-Cooled Preventive Maintenance Kit combination covers the motor-lubrication portion of the 8,000-hour major-service program for the R90–110 I configuration. The published service table identifies 47555208001 as the 8,000-hour air-cooled preventive-maintenance package and specifies one 39218193 Motor Grease SHC220.

Electric-motor bearings operate continuously in compressor service and rely on appropriate lubrication to control friction, wear, and temperature. Motor grease is therefore a dedicated maintenance consumable and should not be treated as a generic shop lubricant.

Ingersoll Rand's parts site identifies 39218193 simply as Motor grease, while applicable compressor documentation gives the more specific lubricant identification Mobilith SHC 220 (39218193) for 60 Hz motors. This distinction is useful for maintenance and purchasing teams because it links the OEM part number to the specified lubricant product.

The direct relationship between the requested references is documented in the R90–110 I service configuration. The 47555208001 package includes the 23429822 air filter, 23424922 coolant filter, 23545841 separator, 23497001 pre-filter, 23531577 minimum-pressure-valve kit, 47552954001 temperature-sensing valve kit, 47553880001 inlet-valve kit, and 39218193 motor grease.

This demonstrates that 47555208001 is a comprehensive major-maintenance event rather than a filter-only service. Motor lubrication is one part of a broader program covering filtration, separation, pressure control, temperature control, intake control, and other service requirements.

Correct grease selection is particularly important because different greases can use different base oils, thickeners, and additive systems. Ingersoll Rand specifically warns that alternative greases can shorten motor life because of incompatibility and instructs users to follow the motor's special grease-information nameplate where provided.

Grease quantity is equally important. Ingersoll Rand documentation warns that over-greasing can cause bearing and motor failure and emphasizes keeping dirt and contaminants out of the bearing during lubrication. The actual amount should therefore be taken from the applicable motor documentation rather than estimated from the grease-container size.

Before lubrication, the grease fitting and surrounding area should be cleaned. Contamination entering the bearing can compromise otherwise correct lubrication and accelerate bearing wear.

The motor's operating frequency should also be checked. The referenced Ingersoll Rand documentation specifies Mobilith SHC 220 for 60 Hz motors, while it identifies Esso Unirex N3 (92844729) for 50 Hz motors. This is a strong example of why 39218193 should not be assumed to be universal across every motor configuration.

Maintenance teams should also distinguish motor grease from compressor lubricants. 39218193 is intended for applicable motor-bearing lubrication; it is not the compressor's circulating oil and should not be used in the air end or oil circuit.

The 8,000-hour service interval also distinguishes 47555208001 from the lower-interval R90–110 maintenance packages. The published service data shows separate preventive-maintenance packages for earlier service stages, while 47555208001 represents the major air-cooled event.

For purchasing departments, retaining the complete maintenance-kit number together with 39218193 provides clear traceability between the scheduled service event and the individual motor-lubrication consumable. This is particularly useful when individual parts are replenished separately from complete kits.

The OEM part number is also independently supported in Ingersoll Rand's genuine-spares catalog and other published parts lists, where 39218193 is described as motor grease or SHC220 motor grease.

During service, the technician should record the lubricant used, operating hours, and amount applied where the site's maintenance procedure requires those records. This creates useful history for subsequent motor-bearing servicing.

Exact grease container size, formulation details beyond the published SHC220 identification, package dimensions, kit weight, and motor-specific grease quantities for every 47555208001 configuration were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and service professionals, 47555208001 and 39218193 provide a clear reference for motor-lubrication service within the 8,000-hour air-cooled R90–110 maintenance program. Correct grease identification, compatibility control, contamination prevention, and careful application can help support reliable motor-bearing performance.

Technical Specifications

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