Improved Exhaust Manifolds {1059}
- Machine Engines:
- 3408E
- 3412E
Description of Change: The exhaust manifolds for 3408E and 3412E Machine Engines have been redesigned in order to provide improved reliability.
Adaptable To: The changes to the exhaust manifold groups are detailed in Table 1. These changes are adaptable to all earlier 3408E and 3412E Machine Engines. Tables 2 and 3 show a breakdown of the parts within each of the new exhaust manifold groups, as these parts are not serviced at the group level.
