arm (outside). 

5.

Install the main bearings paying attention to the direction.

CAUTION:

• Before installing main bearings, apply new engine oil to the bearing surface (inside). Do not

apply new engine oil to the back surface, but thoroughly clean it.

• When installing, align main bearing to the center position of cylinder block and main bearing

cap.

• The difference (A) between main bearing upper (1) and

main bearing lower (3) should be 0.85 mm (0.033 in) or
less when installing.

• Ensure the oil holes on cylinder block and oil holes (A) on

the main bearings (1) are aligned.
