Installation Procedure

Note: Refer to Specifications to identify the bucket families.

1. Make sure that the bores in the power link and the bore in the stick are thoroughly clean and free of dirt and debris prior to the installation of the sleeve bearings.

   Note: Make sure that the bearings are installed in the bore so that the identification numbers of the bearings are facing outward.
