Introduction
The Ingersoll Rand 47642697001 39454558 Motor-to-Gearcase Gasket is a maintenance-focused sealing component for compatible compressor drive assemblies. 47642697001 identifies a gearbox maintenance kit associated with older Cobra M90-160 compressors, while 39454558 serves the critical sealing function at the motor-to-gearcase interface.
The motor and gearcase form an important part of the compressor's mechanical drive system. Their mating surfaces must remain securely sealed throughout operation, particularly where lubricant is contained within the gearcase. A gasket that has deteriorated or been disturbed during disassembly can become a potential source of leakage after reassembly.
For gearbox overhaul work, replacing the gasket provides a straightforward way to renew the static sealing interface. It also helps maintenance personnel avoid relying on an old compressed gasket whose original sealing characteristics may have changed during years of thermal cycling and mechanical service.
The relationship between 47642697001 and 39454558 should be treated as an associated maintenance reference rather than confirmation of package contents. The first number identifies the gearbox maintenance kit, whereas 39454558 identifies a specific gasket. The applicable compressor bill of materials should therefore be checked before assuming that this gasket is supplied with the complete kit.
Correct installation is just as important as correct part selection. Mating surfaces should be clean and free from damage, the gasket should be positioned correctly, and fasteners should be tightened according to the applicable service procedure. These details help maintain consistent joint compression and minimize the risk of leakage.
For purchasing and maintenance teams, using the correct Ingersoll Rand gasket reference can simplify gearbox service planning and reduce the possibility of rework. When servicing older compressor platforms, verifying the model and serial number before ordering remains the best way to confirm application-specific fitment.
