(A) or protractor. Do not judge by visual inspection without
the Tool (A).
• After installing the main bearing cap bolts, check that crankshaft can be rotated smoothly by hand.
• Check crankshaft end play. Refer to EM-102, "
Inspection".
9. Install piston to connecting rod with the following procedure:
a. Using a heat gun, heat the piston until the pist on pin can be pushed in by hand without excess force
[approximately 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin into piston and con-
necting rod.
b. Set so that the front mark (A) on the piston head and the cylin- der number (C) are in the position as shown.
NOTE:
The symbols without notes are for manufacturing.
CAUTION:
Press-fit the piston so as not to damage it.
NOTE:
The joint between the connecting rod and the piston pin is a
press fit.
