  1. Examine connecting rod bolts for stretching (1). Stretching (1) can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt must be replaced.
  2. Before installing the bolts the threads should be cleaned and inspected.
  3. Install clean bolts finger tight. Then alternately torque each bolt to assemble the cap properly.
  4. Tighten the connecting rod cap bolts to specification. See Engine - Specifications .
