  15. When assembling, bolts should be fastened using the plastic angle technique as follows.
    1. Apply oil to the threads and matching areas.
    2. Tighten the connecting rod bolt.

    Tightening torque 

    Connecting rod bolt :

    18 Nm (180 kg.cm, 13 lb.ft) + (90°)

    CAUTION: After removing the connecting rod bolt, do not use it again.
    When using a new bolt, do not tighten the bolt more than 3 times.
