6. Apply Tooling (C) to the corners and the sides of rear main bearing cap (8). Install rear
main bearing cap (8) to the cylinder block so that the rear face is even with the rear face of
the cylinder block.
7. Apply soapy water to seals (9). Position seals (9) in the grooves on rear main bearing cap
(8) with the rounded edges of seals (9) toward the outside. Use Tooling (D) in order to push
seals (9) into position. This will reduce the risk of damaging the metal cores of seals (9).
Apply Tooling (C) around seals (9). Cut off any excess length of seals (9) .

11. Install the lower half of the connecting bearings into the corresponding connecting rod caps
and install connecting rod caps (5) .
Note: Align the tabs on the back of the connecting rod bearings with the tab grooves in
connecting rod caps (5). Install new bolts (4) and the new nuts. Tighten bolts (4) to a torque
of 103 ± 5 N·m (76 ± 4 lb ft).
