1. CRANKSHAFT AND PISTON
1) Install connecting rod bearings on connecting rods and connecting rod caps.

CAUTION: Apply oil to the surfaces of the connecting rod bearings.

2) Install connecting rod on crankshaft.

CAUTION: Position each connecting rod with the side marked facing forward.

3) Install connecting rod cap with connecting rod nut. Ensure the arrow on connecting rod cap faces the front during installation.

CAUTION:
- Each connecting rod has its own mating cap. Make sure that they are assembled correctly by checking their matching number.
- When tightening the connecting rod nuts, apply oil on the threads.





4) Installation of piston rings and oil ring
(1) Install oil ring spacer, upper rail and lower rail in this order by hand. Then install second ring and top ring with a piston ring expander.
(2) Position the top ring gap at A or B in the Figure.
(3) Position the second ring gap at 18O~ on the reverse side for the top ring gap.





(4) Position the upper rail gap at C or D in the Figure.
(5) Position the expander gap the at 18O~ of the reverse side for the upper rail gap.
(6) Position the lower rail gap at E or F in the Figure.

CAUTION:
- Ensure ring gaps do not face the same direction.
- Ensure ring gaps are not within the piston skirt area.





5) Install circlip.
Install circlips in piston holes located opposite service holes in cylinder block, when positioning all pistons in the corresponding cylinders.

CAUTION: Use new circlips.
