CRANKSHAFT
CAUTION:
Do not interchange the big end bearings and
connecting rods. To obtain the correct crank-
shaft-pin-to-big-end-bearing clearance and
prevent engine damage, the big end bear-
ings must be installed in their original posi-
tions.
a. Clean the big end bearings, crankshaft pins,
and bearing portions of the connecting rods.
b. Install the big end upper bearing into the con-
necting rod and the big end lower bearing
into the connecting rod cap.
NOTE:
Align the projections a on the big end bearings
with the notches b in the connecting rod and
connecting rod cap.
c. Put a piece of Plastigauge
shaft pin.
d. Assemble the connecting rod halves.
NOTE:
S Do not move the connecting rod or crankshaft
until the clearance measurement has been
completed.
S Apply molybdenum disulfide grease onto the
bolts, threads, and nuts seats.
S Make sure that the "Y" mark c on the connect-
ing rod faces towards the left side of the crank-
shaft.
S Make sure that the characters d on both the
connecting rod and connecting rod cap are
aligned.
e. Tighten the connecting rod nuts.
CAUTION:
S When tightening the connecting rod nuts,
be sure to use an F-type torque wrench.
S Without pausing, tighten the connecting
rod nuts to the specified torque. Apply con-
tinuous torque between 2.0 and 3.6 mSkg.
Once you reach 2.0 mSkg, DO NOT STOP
TIGHTENING until the specified torque is
reached. If the tightening is interrupted be-
tween 2.0 and 3.6 mSkg, loosen the con-
necting rod nut to less than 2.0 mSkg and
start again.
