SERVICE MAGAZINE, APRIL 19, 1982, PAGE 9. In the article "New Broken Link Spring Used In Governor", some wrong models were given in the subtitle. The new 2W2216 Broken Link Spring is not used on 245 Excavators or 245 Front Shovels. Make a mark through these models.

--------------- END SUPPLEMENT ---------------

Description of Change: The governor in the above models now has a new broken link spring. These new springs are used only in the above models with direct injection engines and scroll fuel systems. This spring was changed to increase the force available to the rack. The increase in spring force will improve rack setting accuracy. With the former link spring, adjustment of the rack settings was difficult.

Adaptable As: The new 2W2216 Broken Link Spring is a direct replacement for the former 1N3801 Broken Link Spring on the above models.
