Lubricate main bearing studs (8) with clean engine oil. Use Tooling (H) and a suitable torque wrench in order to check the torque on main bearing studs (8). Tighten main bearing studs (8) to a torque of 100 20 N m (74 15 lb ft). Note: Be sure that the back of the main bearing is clean and free from oil.
Lightly lubricate the upper crankshaft main bearing with clean engine oil. If necessary, use Tooling (E) in order to rotate the crankshaft and remove main bearing. Use Tooling (F) and install the upper crankshaft main bearing into the cylinder block.

Start at the front of the engine and tighten bolts (3) on the right side of the cylinder block to a torque of 100 20 N m (74 15 lb ft).
Illustration 11 g01212105Note: Show 14 to 15 threads or 28 to 30 mm of protrusion of the stud above the nut before tension is applied. Show 16 to 17 threads or 32 to 34 mm of protrusion of the stud above the nut after tension is applied.
Install Tooling (A) onto the studs for the crankshaft main bearing cap. Tighten the threaded collar of Tooling (A). Attach Tooling (B) onto Tooling (A). Attach Tooling (C) onto Tooling (D). Apply approximately 135 MPa (19580 psi) of pressure to Tooling (B). Use the drive on Tooling (A) in order to tighten the nuts for the crankshaft main bearings. Release the pressure on Tooling (A). Reapply approximately 135 MPa (19580 psi) of pressure to Tooling (A). Recheck nuts (3) for tightness. Remove Tooling (A).
