(A) Cut out for piston cooling jet
(Y) Cooling jet
(X) Connecting rod identification marks
5. Ensure that Tooling (B) is installed correctly and
that piston (4) can easily slide from the tool.
Note: Ensure alignment of the connecting rod
assembly to the crankshaft journal.
6. Carefully push the piston and the connecting rod
assembly into the cylinder bore and onto the
crankshaft pin.

Typical example
7. Ensure that etched number in Position (X) on
connecting rod cap (1) matches etched number in
Position (X) on connecting rod (3). Ensure the
correct orientation of connecting rod cap (1). The
locating tab for the upper bearing shell and the
lower bearing shell should be on the same side.
Install the connecting rod cap (1) and install new
bolts (2).
8. Tighten the new bolts to 50 N·m (37 lb ft). Turn the
bolts for an additional 70 degrees in a clockwise
direction. Use Tooling (C) in order to achieve the
correct final torque.
9. Ensure that the installed connecting rod assembly
has tactile side play. Rotate the crankshaft in order
to ensure that there is no binding.
10. Repeat Step 1 through Step 9 in order to install
the remaining pistons and connecting rod
assemblies
