The following procedure applies to all of the connecting rods.

CAUTION:

Do not interchange the big end bearings and connecting rods. To obtain the correct crankshaft-pin-to-big-end-bearing clearance and prevent engine damage, the big end bearings must be installed in their original positions.

a. Clean the big end bearings, crankshaft pins, and bearing portions of the connecting rods.

b. Install the big end upper bearing into the connecting rod and the big end lower bearing into the connecting rod cap.

Align the projections ® on the big end bearings with the notches ® in the connecting rod and connecting rod cap.

c. Put a piece of Plastigauge® ® on the crankshaft pin.

d. Assemble the connecting rod halves.

CDo not move the connecting rod or crankshaft until the clearance measurement has been completed.

CApply molybdenum disulfide grease onto the bolts, threads, and nuts seats.

CMake sure that the "Y" mark © on the connecting rod faces towards the left side of the crankshaft.

CMake sure that the characters ® on both the connecting rod and connecting rod cap are aligned.

e. Tighten the connecting rod nuts.

CAUTION: _

When tightening the connecting rod nuts, be sure to use an F-type torque wrench. GWithout pausing, tighten the connecting rod nuts to the specified torque. Apply continuous torque between 2.0 and 3.6 mGkg. Once you reach 2.0 mGkg, DO NOT STOP TIGHTENING until the specified torque is reached. If the tightening is interrupted between 2.0 and 3.6 mGkg, loosen the connecting rod nut to less than 2.0 mGkg and start again.

Refer to "INSTALLING THE CONNECTING RODS".

Connecting rod nut 36 Nm (3.6 mCkg)

f. Remove the connecting rod and big end bearings.

Refer to "REMOVING THE CONNECTING RODS".

g. Measure the compressed Plastigauge® width © on the crankshaft pin.

If the clearance is out of specification, select replacement big end bearings.
