Tooth retainer 980/84767 JCB JS, aftermarket

Tooth retainer 980/84767 is an aftermarket part for the JCB JS crawler excavators. According to the product card, this part is a tooth retainer.

The retaining pin secures the bucket tooth (tip) to the tooth adaptor. It usually works together with a rubber or spring retainer and stops the tooth coming off while digging. A worn or bent pin, or one with a failed retainer, lets the tooth come off and be lost; the adaptor then works directly in the material and wears fast, and a lost tooth that gets into a crusher can cause serious damage. The pin is chosen by tooth system, as different systems of the same tooth size use different pins. The bucket teeth and their pins are inspected at the start of every shift. When a new pin is fitted, the rubber lock or washer is replaced too, as the old locking element no longer holds the pin firmly.
