Rod Bearing Cap
Rod Bearing Cap1. The connecting rod bolts should be examined before reuse. If the bolt threads are damaged, the bolt should be replaced. Hand-thread the nut to the full length of the bolt threads. If the nut does not run down smoothly, the bolt should be replaced.
2. Before installation of each nut, apply engine oil to the threaded portion and bearing surface of the nut.
3. Loosely tighten each nut to the bolt.
4. Then tighten the nuts alternately to a torque of 20 ± 2 Nm (15 ± 1 ft. lbs.) to install the cap properly.
5. Make a paint mark on the head of each nut.
CAUTION:
- If the nut is turned less than 90 degree angle, proper fastening may not be achieved. Be careful to tighten the nut exactly at a 90 degree angle.
- If the nut is overtightened (exceeding 94 degree angle), loosen the nut completely and then retighten it by repeating the tightening procedure from step 3.
6. Make a paint mark on the bolt end at the position 90 degree angle to 94 degree angle from the paint mark made on the nut in the direction of tightening the nut.
7. Turn the nut further 90 degree angle to 94 degree angle and make sure that the paint marks on the nut and bolt are aligned.
