NOTICE
When retightening the bolts, never adjust them by turning counter-
clockwise, even if they have been retightened more than the specified
angle above.
SHTS011060200162
If the angle of bolts is adjusted to the specified angle by turning coun-
terclockwise, the axial force of the bolts might fall short and it is
feared that this could reduce the engine reliability. Also there is a pos-
sibility that this could reduce the number of times a bolt can be
reused.
Apply engine oil to the piston, cylinder liner and connecting rod bear-
ing, then compress the piston ring using the special tool.
SST: Piston ring holder (S0944-11370)
When installing the piston, be careful that the cooling jet is not
struck by the connecting rod.
Make sure that the hollow-mark on the piston is at the exhaust
side.
Insert the piston into the cylinder liner.
Measure the length of the bolts, if the length is A or more, replace with
new bolts.
Dimension A
Apply clean engine oil to the bolt thread and the bolt seat surface of
the connecting rod cap.
Tighten the connecting rod bolt to the specified torque.
Tightening Torque:
69 Nm {700 kgfcm, 51 lbfft}
Mark the bolt heads in the same direction with paint.
Tighten the connecting rod bolt 90 (1/4 turn).
Tighten the connecting rod bolt 45 (1/8 turn).
Make sure that the paint marks face the same direction.
