Preparation before installing pistons
Clean the cylinder liner bore surface and crank pin by
wiping with a cloth, then coat it with engine oil.
Pistons for right bank cylinders
Turn the crankshaft in the normal direction until the
number (stamped on the damper) (A) of the cylinder to
which the piston is to be installed is at the position of
approximately SO* before top dead center.
Pistons for left bank cylinders
Turn the crankshaft in the normal direction until the
number of the cylinder to which the piston is to be in-
stalled is at the position of about 50° after top dead
center.
Connecting rod bearing upper shells
Install the upper shell of the bearing in the rod by
fitting its locating lug in the lug groove of the rod (A).
Coat the inside surface of the shell with engine oil.
Make sure the oil holes in the rod and bearing are
aligned.
Inserting pistons
1. Put the connecting rod in the cylinder liner, and
carefully rest the piston on top of the crankcase.
IMPORTANT! Make sure the arrow mark above
the "CAM-arrow"(A) on top of the piston points
towards the camshaft(B).
IMPORTANT! When placing the connecting rod
in the liner, have another service man to ob-
serve the rod through the inspection hole to
keep it away from the oil cooling nozzle. Do not
rotate the piston.
