( 1 ) The Shaft is a component of the Bracket Assembly.The new components that are identified in Table 2 are effective with the Off-Highway Trucks that follow: 785C (S/N: APX333-UP; 5AZ274-UP), 789C (S/N: 2BW567-UP) and 793C (S/N: ATY520-UP).The former 113-8158 Shaft and the former 113-8159 Retaining Washer can be modified and used. See the Modification Procedure that follows.Modification Procedure
Check the Dimension (X) that is identified in Illustration 1. If the distance is less then the minimum, the bolts (6) may contact the Plug (A). In order to increase the Dimension (X), remove the Plug (A) from the Fan Adapter (B). Tap the hole in the Fan Adapter with additional threads. The additional threads will allow the Plug to be installed farther into the Fan Adapter. This will increase the distance between the Plug (A) and the bolts (6).
