In general, a serrated lock washer is a flat washer with small teeth on one face that bite into the surface beneath it, helping resist loosening of a fastener under vibration. Its exact dimensions, material and construction are not stated in the catalog listing and should be confirmed against the listing before use.
Order using part number 0134369 exactly as listed. Before ordering, check the catalog association with the Caterpillar 3412 engine arrangement and its recorded conditions against your machine's serial number and configuration, since the listing does not confirm fitment across all configurations.
