5. Push connecting rod and piston as far up into cylinder as possible. Using a wooden dowel, tap gently on piston to release it from cylinder.
6. Repeat this procedure for each cylinder.
7. Mark tops of pistons with corresponding cylinder numbers they were removed from.
8. Using a piston ring expander, remove piston rings.
9. Hold piston upright and gently move connecting rod.
10. Release connecting rod and observe its movement.
Notice: Do not swing connecting rod widely. Constant, hard contact with piston will cause a bell-mouth condition mat will require piston
replacement.
11. If connecting rod does not move freely, check piston pin bore and connecting rod for straightness and deformation.
12. Remove piston pin clip from ends of piston pin bore.
13. Tilt piston and allow piston pin to slide out into your hand. Piston pins may need to be pressed out.
Notice: Do not allow pins to drop to the ground.
