Ordering by number: this is P006239, which also shows up as 3310104342, the Chicago Pneumatic lock washer. It spreads clamp load and protects the face under the fastener routine hardware, but the wrong one changes how the joint holds torque.
It is called out in the parts diagram for the CP 1230 1230S 1230SVR Paving Breaker and CP 1230 SPDR 1230S SPDR Spike Driver. Compare it to the reference callout on the diagram to be sure it is the position you need.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
