  1. Remove old rings with a ring expander tool or by spreading the ring ends with your thumbs and lifting the rings up evenly (figure 103).
  2. Carefully remove all carbon from the ring grooves. Inspect grooves carefully for burrs, nicks, or broken and cracked lands. Recondition or replace piston if necessary.
  3. Check end gap of each ring. To check ring, insert the ring into the bottom of the cylinder bore and square it with the wall by tapping with the piston. The ring should be in about 5/8 in. (15mm).

    Insert a feeler gauge as shown in Figure 104. Compare gap with Table 1. If the gap is smaller than specified, hold a small file in a vise, grip the ends of the ring with your fingers, and enlarge the gap. (See Figure 105.

  4. Roll each ring around its piston groove as shown in Figure 106 to check for binding. Minor binding may be cleaned up with a fine cut file.
  5. NOTE: Install all rings with their markings facing up.

(Refer to Figure 96 for this procedure)
