Service limit 15.06mm 0.593 in.
• If the connecting rod is damaged beyond the service limit, the crankshaft should be replaced.
PISTON RING INSTALLATION GAP:
• Apply oil on every piston ring.
• Enlarge piston rings, while placing them on the piston and move downwards gradually, until piston rings fall
• Mount piston onto the small end of the connecting rod.
