Product Overview
Atlas Copco parts documentation lists 1604077400 as a coupling, and matching application data ties the same hub to numerous XAS portable compressors. The coupling transmits engine power into the compressor drivetrain while accommodating the coupling element used by the machine.
Wear at the hub bore, fastener interface or coupling contact surfaces can create vibration, noise, loss of drive or accelerated coupling-element failure. Because XAS machines span different engines and generations, confirm 1604077400 in the machine parts book before teardown.

Frequently Asked Questions
Is this part only for XAS97/XAS87/XAS77/XAS67?
No. The same part number is documented on several additional XAS models.
Should the flexible coupling element be inspected too?
