Lock Washer carries Chicago Pneumatic part number S008020 (also carried as 3310104341) and is stocked here under CP-S008020. It sits under the fastener to preserve the mating face and hold tension in a joint that vibrates constantly.
It appears on the CP 0020 Sump Pump breakdown. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
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.
