2. Assemble the 196-8014 Bracket and the 196-8012 Bracket which was removed in Step 1. The alignment for both brackets for the muffler will need to be adjusted. Assemble the right and left bracket to the flywheel housing. The dimension of A and B (both to the center of U-bolt hole) must be 253mm and parallel to each other. Tighten the four bolts to a specified torque of 43 +/- 5 N.m. Refer to Image1.2.1.

3. Assemble the new 196-8015 Stud and set the new 5I-7937 Gasket to the turbocharger. Tighten the stud to a specified torque of 23 +/- 2 N.m.

4. Assemble the 196-8013 Pipe, that was removed in Step 1, to the new 2396659/">239-6659 Muffler. Insert the pipe to the 5I-7639 Clamp, that was removed in Step 1, and join them with the muffler.

5. Place the muffler, that was assembled at Step 4, in the proper position. Tighten the nuts (double nuts) in the turbocharger side, avoiding any overload to the pipe, to a specified torque of 36 +/- 6 N.m. Fix the U-bolt to the bracket ensuring that there is no inclination in the muffler. Tighten the upper nuts to a specified torque of 35 +/- 6 N.m and the bottom nuts to a specified torque of 10 +/- 2 N.m, avoiding any overload to the muffler. Refer to Image1.5.1, 1.5.2, and 1.5.3.
