TM 5-4210-233-14&P-1 5-24.  EXHAUST MANIFOLD-Continued b. Inspection. (1)   Remove all loose scale and carbon that may have accumulated on the internal walls of the exhaust manifold.  This is especially important on turbocharger engines becauseloose scale or carbon could enter and damage the turbocharger. (2)   Examine the exhaust manifold studs for damage, and replace as necessary.  Torque new studs to 25-40 lb-ft (34-54 Nm). (3)   Make sure all gasket material is removed from cylinder head and exhaust manifold mating surface. (4)   Inspect manifold for cracks, damage or warpage. c. Installation. CAUTION Ensure manifold interior is free from scale and carbon.  This will eliminate the possibility of turbocharger damage. (1) Place two new gaskets (8) over studs and up against the cylinder head. NOTE When installing the two metal clad exhaust manifold gaskets be sure the crimped sides of the gaskets face the cylinder head. (2)   Lift right exhaust manifold (3) into engine compartment.  Position the manifold over the studs (7) and up against the exhaust manifold gaskets (8). NOTE Be  sure  the  locating  pads  on  the  exhaust  manifold  rest  on  the cylinder block locating pads. (3)   Install the two hold-down crabs (5), three bevel washers (6),and five nuts (4) on the studs (7), and draw the exhaust manifold up against the gaskets.  Set the bevel washers in position so that outer diameter  will  rest  on  the  manifold  and  the  crown  at  the  center  is  next  to  the  nut.    Tighten  the exhaust manifold stud nuts (4) from the center of the exhaust manifold outward, alternating toward either end.  Torque the nuts to 30-35 ft lb (41-47 Nm). (4)   Install the right exhaust manifold to turbocharger pipe (1) into position, and secure using two seal clamps (2) Do not allow exhaust piping to impose excessive loads on turbocharger.  Tighten seal clamps firmly. (5)   Tighten dipstick bracket screw. (6)   Repeat steps 1 through 4 to install left exhaust manifold. d. Follow-on Maintenance. (1)   Install engine enclosure (see para 4-127). (2)    Connect batteries (see para 4-114). 5-164
