°
C (140 to 158
°
F)]. From the front to the rear, insert piston
pin into piston and connecting rod.

8. Using a piston ring expander (commercial service tool), install
piston rings.
CAUTION:
• Never damage piston.
• Never damage piston rings by expanding them excessively.
• Position each ring with the gap as shown in the figure referring
to the piston front mark.
CAUTION:
Never contact the rail end gap under the oil ring with the
oil drain cast groove of piston.
• Install second ring with the stamped surface facing upward.
9. Install connecting rod bearing upper (2) and lower (3) to con-
necting rod (1) and connecting rod cap (4).
• Install the connecting rod in the dimension shown in the figure.
• Check that connecting rod bearing oil hole (A) is completely in
the inside of connecting rod oil hole chamfered area (B).
• When installing connecting rod bearings, apply new engine oil
to the bearing surface (inside). Do not apply new engine oil to
the back surface, but thoroughly clean it.
NOTE:
• There is no positioning tab.
• Install the connecting rod bearings in the center of connect-
ing rod and connecting rod cap as shown in the figure. For
service operation, the center position can be checked, visu-
ally.

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE
• Measure the side clearance between connecting rod and crank-
shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crankshaft
also.
