Bucket tip retainer kit 993/99643 JCB, aftermarket

For the JCB machines: bucket tip retainer kit 993/99643, an aftermarket part. The retainer kit is for the 993/99642 tip.

When the bucket teeth are changed, renewing the pins and retainers is recommended, as an old pin is usually worn and has lost its spring. Check that the pin is fully seated and its end does not stand proud of the tooth surface. 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.
