(6) Connecting rod nut
Use the following procedure to tighten the connecting rod nut :
- Use new engine oil to lubricate the bolt threads and the seating faces between the cap and the nut before assembly.
- Tighten the connecting rod nuts.
Torque for nuts ... 82 ± 8 N·m (60 ± 6 lb ft)
- Place a mark on each nut and on the end of each bolt. Refer to Illustration 3.
