SPEEDAIRE 22XJ99 Repair Kit

This SPEEDAIRE repair kit is designed for owners of the Grainger 22UX79 air compressor who need to restore worn internal components. It provides the specific bearings, pins, shims, springs, vanes and shaft seal required for that model. The kit suits maintenance technicians and DIY users performing scheduled overhauls on compatible equipment. It is not intended for compressors using different part numbers or unrelated pump designs.

Thermals Noise and Power

As a collection of mechanical replacement parts, this kit does not consume electricity, generate heat or produce audible noise during installation or operation. The components function passively within the compressor pump to reduce friction and seal the rotating assembly. Performance characteristics such as temperature rise or sound level depend entirely on the host machine and its operating condition. No power draw or thermal rating applies to the kit itself.

Upgrade Context

This kit replaces factory-original wear items inside the Grainger 22UX79 compressor when bearings, vanes or seals have degraded through normal use. The jump is worth it when the pump shows reduced pressure output, increased vibration or visible leakage around the shaft. It does not increase the compressor’s rated capacity or change its duty cycle. Owners of other Speedaire or Grainger models should verify the exact part number before ordering.

Questions about this item

How do I install the SPEEDAIRE 22XJ99 repair kit on my 22UX79 compressor, and what step is commonly missed?

Disassemble the pump, replace the two bearings, two pins, two shims, four springs, four vanes, and the shaft seal as a complete set; the step often missed is installing all four vanes with the correct orientation so they seat evenly against the rotor.

Which components in the SPEEDAIRE 22XJ99 kit will need replacement again under normal maintenance cycles?

The four vanes and the shaft seal are wear items that typically require replacement before the bearings, pins, springs or shims during routine service intervals.

What is the first limiting factor when the rebuilt pump runs continuously at full load?

Heat buildup from vane friction and shaft-seal wear becomes the primary limit, causing pressure drop and increased oil carry-over before bearing fatigue appears.
