3508 (95Y, 68Z) Industrial, 3508 (23Z, 70Z) Generator Set, 3508 (6TJ) Locomotive, 3512 (49Y, 65Z) Industrial, 3512 (24Z, 67Z) Generator Set, 3512 (2WK) Locomotive, 3516 (71Z) Industrial, 3516 (73Z) Generator Set EnginesDescription of Change: New exhaust manifold sections are used in the exhaust manifold groups on these engines. The new exhaust manifold sections are the end sections that connect to the turbocharger inlet. The new manifold sections included a threaded port where a temperature sensor can be installed. The temperature sensor would measure turbocharger inlet temperature.
Locations of the new 128-9509 Exhaust Manifold Section (1) and 126-9190 Exhaust Manifold Section (2) in 9Y-4862, 9Y-4863, or 9Y-4864 Exhaust Manifold Groups. Plug (3) is removed when the temperature sensor is installed.Adaptable To: The new 128-9509 Exhaust Manifold Section and 8T-6765 Pipe Plug are a direct replacement for the former 7E-8479 Exhaust Manifold Section. The new 126-9190 Exhaust Manifold Section and 8T-6765 Pipe Plug are a direct replacement for the former 7E-8482 Exhaust Manifold Section. The former exhaust manifold sections are canceled. The new exhaust manifold sections are used in the 9Y-4862 (3516 engines), 9Y-4863 (3512 engines), and 9Y-4864 (3508 engines) Exhaust Manifold Groups.
