Piston- Install - Mitsubishi S6R Series Service Manual

Chapter 7 ASSEMBLY OF BASIC ENGINE
(5) Install piston into cylinder liner by tapping the piston
head with soft-head hammer.
Note: Make sure that the piston is not caught in the cylinder
liner, or the connecting rod big end does not hit the
crank pin.
(6) Verify the proper placing of upper connecting rod bear-
ing shell through the inspection window on crankcase
side. If the bearing shell is not placed properly, push the
bearing upward with your hand to correct the position.
(7) If the upper connecting rod bearing is displaced from
connecting rod big end, rotate the crankshaft to make a
space between the connecting rod big end and crankpin.
Then, insert the connecting rod bearing, sliding on the
crankpin, and make sure that the lug on the bearing
shell is correctly positioned in the lug slot of the rod.
