BAR 7V3687 - Caterpillar

Loosen clamps (24), clamps (25), and clamps (26). Rotate turbine housing (23) away from bellows (27).Note: All clamps are designed for one time usage must be discarded.
Remove exhaust manifold (17).
Remove inlet manifold (18), exhaust manifold (18), and the bellows together.
Repeat Step 1 through Step 15 for the opposite side.Installation Procedure

Illustration 11 g06088436Note: Position the clamps on the exhaust manifolds before installation. All the clamps must be new.
Attach a suitable lifting device onto exhaust manifold (17). The weight of exhaust manifold (17) is approximately 48 kg (105 lb). Position exhaust manifold (17). Attach inlet manifold (18), exhaust manifold (17), and the bellows to the installed exhaust manifold (17). Install Tooling (A) and tighten the bellows.
Rotate and align turbine housing (23). Install new exhaust bellows (27).
Install clamps (25), clamps (24), and clamps (26).

Remove Tooling (A). Install bolts (21) in exhaust manifolds (17). Tighten bolts (20) and bolts (21).
If necessary, inspect the threads and the sealing surface for damage on the temperature sensor adapter (22) and the thermowell. Apply Tooling (C) on the threads and install the thermowell. Tighten the thermowell to a torque of 47 4 N m (35 3 lb ft).
Install temperature sensor adapter (22) and tighten temperature sensor adapter (22) to a torque of 45 5 N m (34 4 lb ft).Note: Attach suitable rigid support to exhaust manifolds prior to Install. The rigid support will allow removal of exhaust manifolds (17) without disruption of the bellows joints.

Tighten clamps (15). Ensure that inlet manifold (18), clamps (16), and bolts (19) have not been removed or loosen.
Use Tooling (B) to check bellows to verify alignment by running the shim between the corrugations. Repeat the process if the bellows do not rotate freely between the corrugations.
Repeat Step 1 through Step 8 for the opposite side.
