This is Atlas Copco part number 9234012650 tool chuck – complete 1 x 4 1/4″, stocked at Crowder Supply as AC-9234012650. This part keeps the steel captive in the tamper under repeated impact, so it is inspected at every steel change and replaced on condition rather than on a schedule.
The published breakdown lists it on the Cobra TTe TTeAWD Gas Tie Tamper and Cobra Pro I Gas Paving Breaker, and on 2 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
