Scrankshaft-pin-to-big-end-bearing clear-
ance
Out of specification
! Replace the big end
bearings.
Crankshaft-pin-to-big-end-bearing
clearance
0.028
X 0.052 mm
(0.0011
X 0.0020 in)
The following procedure applies to all of the
connecting rods.
Do not interchange the big end bearings and
connecting rods. To obtain the correct
crankshaft-pin-to-big-end-bearing clear-
ance and prevent engine damage, the big
end bearings must be installed in their origi-
nal positions.
a. Clean the big end bearings, crankshaft pins,
and the inside of the connecting rod halves.
b. Install the big end upper bearing into the con-
necting rod and the big end lower bearing
into the connecting rod cap.
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
1
on the crank-
shaft pin.
d. Assemble the connecting rod halves.
SDo not move the connecting rod or crankshaft
until the clearance measurement has been
completed.
SLubricate the bolt threads and seats with mo-
lybdenum disulfide grease.
SMake sure that the “Y” mark
c
on the connect-
ing rod faces towards the left side of the crank-
shaft.
SMake sure that the characters
d
on both the
connecting rod and connecting rod cap are
aligned.
