Connecting Rod Bearing: Specifications

TIGHTENING SPECIFICATIONS
1. Examine the connecting rod bolts and nuts before reuse. If the bolt threads are "necked down", replace the bolts. Necking can be checked by running a nut with fingers to the full length of the bolt's thread. If the nut does not run down smoothly, replace the bolt.
2. Before installing the nuts, the threads should be oiled with clean engine oil.
3. Install both nuts on each bolt finger tight, then alternately torque each nut to assemble the cap properly.
4. Tighten the nuts to 20 Nm (14.5 ft. lbs.).





5. Paint a mark on the nut head.
6. Use the painted mark as a reference, and paint another mark on the area next to the bolt 90° clockwise. Tighten an additional 90° - 100°, til the paint marks are in alignment.

CAUTION:
- If the tightening angle is less than 90°, the bolt will be loosened. Be careful to observe the tightening angle.
- If the tightening angle is more than 100°, remove the nut and repeat the procedure.
