PROBLEM

The weld between the main stick fabrication and the boss on the stick nose can crack in difficult applications such as when digging in rocky or very hard ground. The stick fabrication can be strengthened with plates that can be welded to both sides, immediately behind the boss. The boss on the stick nose can also wallow out. An improved boss can be welded to the stick nose in order to reclaim the stick and provide a boss that is more resistant to wear.

This service letter is in two groups.

Group 1 deals with machines that require strengthening of the stick due to cracking of the weld between the boss and the stick fabrication. In some cases the weld may be cracked. In other cases the boss may have become completely detached. The stick is almost always repairable. On these machines the original boss can be left in place and the plates can be welded to the stick. Alternatively, the existing boss can be removed and the new boss can be installed along with the plates. This part of the service letter allows for the new boss to be welded in place.

Group 2 deals with machines that only require a new boss. Some machines may exhibit wallowing out of the boss while the stick fabrication remains sound. This part of the service letter allows for the new boss only to be welded in place.

The salvage procedures are described in Special Instruction REHS2801.
