NOTE:

Make sure the piston ring grooves are clean and free of nicks and burrs.

  1. Measure the piston ring side clearance with a feeler gauge (1) as shown in illustration. Make sure the feeler gauge fits snugly between the piston ring land and the piston ring, replace any ring not within specification.
    NOTE:

    Make sure the marks on the compression rings face upward.

  2. Rotate the ring around the piston. The ring must rotate in the groove with out binding.
