c. Repair.

NOTE

Whenever cylinder liners are removed from an engine, the block bores must be inspected. Before

attempting to check block bores, hone them throughout their entire length until about 75% of the area

above the ports has been cleaned up.

(1) Use a hone in which the cutting radius of the stones can be set in a fixed position rather than a spring-

loaded hone.
