TM 9-2320-209-10-1 f. Exhaust System. There are different exhaust system setups used on the trucks covered in this manual. The following paragraphs note the differences in exhaust systems used with particular engines, or with certain trucks. (1) On vehicles with LDS 427-2 engines (fig. 2-7), the exhaust manifold empties directly into the turbo-supercharger. The pressurized exhaust gasses drive the turbo- supercharger and pass from the turbo-supercharger outlet through an exhaust pipe assembly. The pipe assembly extends back along the right side of the truck, to the outlet, located between the right tandem wheels. 1. Turbo-supercharger 2. Exhaust pipes Figure 2-7.
