3516 (28Z) Vehicular EnginesDescription of Change: A new lifting eye assembly (see Illustration 1) is available for these engines. The new lifting eye assembly includes a new stronger bracket assembly (see Illustration 2). The new bracket assembly has a thicker horizontal mounting flange for increased strength. Also, the new bracket assembly positions the lifting eye connection point higher. This gives the lifting eye greater freedom to rotate. Because of the thicker horizontal mounting flange on the new bracket assembly, longer bracket mounting bolts (2.5 inches verses 2.0 inches) are used to insure proper thread engagement.

The former lifting eye assembly is canceled. The Chart A and the Illustrations 1 and 2 identify the components of the new 150-7972 Lifting Eye Assembly. Chart B identifies the components of the former 8N-8016 Lifting Eye Assembly. For improved serviceability and to help insure the correct mounting hardware is used, each 155-0726 Bracket Assembly includes two brackets, two 6V-9995 Bolts (4), two 5P-8291 Bolts (6), and four 5P-8248 Washers (5). Other than the bolts and washers, the individual pieces of the 155-0726 Bracket Assembly are not serviced separately.
The lifting eye assembly can fail if incorrectly installed. A lifting eye assembly failure can allow the engine to shift or fall. This can result in possible personal injury or death. When installing the lifting eye assembly, be sure to install the correct bolts in the correct locations.
It is important that the bolts (4) and (6) be installed at the locations shown in Illustration 2. Bolt (4) is 1/2inch longer than bolt (6) because the longer bolt is required to provide proper thread engagement when installed through the thicker bracket mounting flange (Y).
