Main bearing caps are identified by identification mark cast on
them. For installation, face front mark to front side.
NOTE:
Main bearing cap cannot be replaced as a single part, because it
is machined together with cylinder block.
7. Install main bearing beam.
Install main bearing beam with front mark facing downward (oil pan side).
Install main bearing beam with front mark facing front of the
engine.

b. Apply new engine oil to threads and seat surfaces of main bear- ing cap bolts.
c. Tighten main bearing cap bolts in several different steps.
d. Turn all main bearing cap bolts 90 degrees clockwise (Angle tightening).
CAUTION:
Use the angle wrench [SST: KV10112100 (BT8653-A)] to
check tightening angle. Do not make judgment by visual
inspection.
After installing main bearing cap bolts, make sure that crank-
shaft can be rotated smoothly by hand.
Check the crankshaft end play. Refer to EM-141, "CRANK-
SHAFT END PLAY" .
9. Install piston to connecting rod as follows:
a. Using a snap ring pliers, install new snap ring to the groove of piston rear side.
Insert it fully into groove to install.
b. Install piston to connecting rod.
Using an industrial use drier or similar tool, heat piston until piston pin can be pushed in by hand without
excess force [approx. 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin into piston
and connecting rod.
