Abstract
A pivot assembly for mounting a bucket to a loader arm wherein shouldered pin adapters having a pin bore are tack welded in the bucket brackets so that when pounding occurs between the pin and pin bore, the pin adapter can be replaced to provide a new pin bore. The pin adapters are located on the interior sides of the bucket brackets and the external corner is indented to define a seal groove which provides an additional seal between the loader arm and the pivot pin.
