    Insert the piston ring squarely into the bottom of the cylinder and measure the ring end gap. (Push the rings into the cylinder with the top of the piston to be sure they are squarely in the cylinder.)

    SERVICE LIMITS:
    Top: 0.5mm (0.02in)
    Second: 0.5mm (0.02in)
    Oil (Side Rail): 0.9mm (0.04in)
