Ingersoll Rand 47588565001 / 22990790 Gearbox Maintenance Package

Introduction

The Ingersoll Rand 47588565001 / 22990790 Gearbox Maintenance Package listing combines a dedicated gearbox-maintenance reference with a separately documented drivetrain gasket.

47588565001 appears in the Ingersoll Rand spare-parts catalog as a Gear Box Maintenance Package. It is grouped with 47588561001 for 2,000-hour preventive maintenance, 47588562001 for 4,000-hour preventive maintenance, 47588563001 for 8,000-hour water-cooled maintenance, 47588564001 for 8,000-hour air-cooled maintenance, and 47588566001 for air-cooled hose maintenance.

This grouping indicates that 47588565001 belongs to a structured maintenance-parts family intended to support scheduled service of the compressor system.

The gearbox is a critical part of the compressor drivetrain. It transfers power between the motor and driven compressor components while maintaining the required speed relationship between the connected shafts. Proper lubrication and sealing are therefore essential to drivetrain reliability.

The associated reference 22990790 is more specifically defined. Ingersoll Rand parts listings identify it as “Gasket Round 455 X 550 IEC 250 MTR.” An independent OEM parts listing likewise describes it as a genuine Ingersoll Rand gasket for an IEC 250 motor.

A drivetrain parts list provides additional context by showing 22990790 as a gasket within an IEC 250 motor/gearcase assembly. The same assembly includes components such as a gearcase, shaft seal, seal housing, shaft sleeve, and O-rings.

This makes the gasket particularly relevant to maintenance where the motor and gearcase interface is opened. Once a sealed joint is disassembled, replacing the gasket rather than reusing an old compressed sealing element is generally important for restoring the intended sealing condition.

The documented 455 × 550 mm size provides useful identification information for 22990790. However, these dimensions should be interpreted as the cataloged gasket size and not as dimensions for the entire 47588565001 maintenance package.

During gearbox maintenance, technicians should inspect the sealing interface carefully. Old gasket material should be removed without damaging the mating surfaces, and any corrosion, scoring, distortion, or contamination should be corrected according to the applicable service procedure.

Lubricant condition should also be assessed during gearbox service. Abnormal contamination, metal particles, discoloration, or an unexpected lubricant level can indicate issues that should be investigated before the drivetrain is returned to operation.

Fastener condition and tightening sequence are important during reassembly. Uneven clamping can create localized leakage paths, while excessive tightening may distort the housing or sealing interface.

The gearbox should also be checked for abnormal vibration, temperature, noise, and lubricant leakage after service. These operating indicators can help confirm that the drivetrain has returned to normal mechanical condition.

The relationship between the two supplied references should be understood carefully. Public documentation establishes 47588565001 as a gearbox maintenance package and 22990790 as a specific IEC 250 motor gasket, but it does not provide a complete OEM bill of materials proving that 22990790 is the only or complete content of 47588565001.

Exact compressor-model coverage for 47588565001 was not reliably established from the available public catalog entry. Therefore, model-specific compatibility should be confirmed using the compressor serial number and applicable parts documentation before purchase or installation.

The supplied pair is treated as one product listing as requested, while the independently documented roles of both references are retained for technical accuracy.

Technical Specifications

The 455 × 550 mm dimensions for 22990790 are supported by multiple parts listings. Exact material, thickness, complete-package dimensions, and verified weights were not established from reliable technical documentation and are therefore not fabricated.

Recommended Companion Models

These references are grouped with 47588565001 in the same maintenance-parts series and provide complementary service coverage for cooling, hose, and scheduled-maintenance requirements. They are companion products rather than automatic substitutes for the gearbox maintenance package.

Frequently Selected Alternatives

These are related Ingersoll Rand gearbox-maintenance references for different compressor families or configurations. They should not be treated as direct substitutes without confirming the compressor model, drivetrain configuration, and serial-number applicability.
