The correct part number for Item 31 is 1012731 Plate Assembly. The correct part number for Item 34 is 7M9831 Screw.
--------------- END SUPPLEMENT ---------------SUPPLEMENT: 03/14/94Service Magazine; November 15, 1993; Page 6; "New Fuel Injection Lines, Clamps, And Brackets Used In Fuel Injection Lines Groups".Item 18 in Chart E and Item 13 in Chart F is identified as a 7M1910 screw. This is NOT correct. the correct Part Number a 7M9910 Screw.

--------------- END SUPPLEMENT ---------------Description of Change: This article supersedes the article with the same title on Page 17 of the May 17, 1993 issue. Improved fuel injection line assemblies, clamps, and brackets are used. The improved lines are manufactured from a stronger material that is more resistant to cracking caused by vibration and high injection pressures. A new stepped washer (collar) is used at each end of the improved line assemblies. The collars provide more support to each end of the lines. The improved fuel line assemblies can be identified by the undercut on the hex nut at each end of the line. See Illustration 5. The new clamps and brackets will help prevent vibrations from damaging the fuel injection lines. The correct clamp and bracket hardware and locations are very important for improved fuel line durability.
Adaptable To: The new components in the 3408 (48W) Machine Engine fuel injection lines groups are identified in Illustration 1 and Chart E. The new components in the 3408 Industrial (67U), Marine (99U), and Generator Set (78Z) Engines fuel injection lines groups are identified in Illustration 2 and Chart F. All the new components are in effect as shown in Chart A. The new components in the 3412 (73W, 1DB) Machine Engine fuel injection lines groups are identified in Illustration 3 and Chart G. The new components in the 3412 Industrial (38S), Marine (60M, 7HG), and Generator Set (81Z, 5AG) Engines fuel injection lines groups are identified in Illustration 4 and Chart H. The new fuel injection lines are in effect as shown in Chart B. The new clamps and brackets are in effect at later serial
