>> G << Connecting Rod Cap Nut Tightening
WARNING: This page is about a different variant/trim than selected.
- Since the connecting rod cap bolts and nuts are torqued using the plastic area tightening method, the bolts should be examined before reuse. If the bolt threads are "necked down", the bolt should be replaced.
Necking can be checked by running a nut with your fingers the full length of the bolt threads. If the nut does not run down smoothly, the bolt should be replaced.
- Before installation of each nut, apply engine oil to the nut.
- Install each nut to the bolt and finger-tighten it. Then tighten the nuts alternately to install the cap properly.
- Tighten the nuts to a torque of 20 N.m (15 ft-lb).
- Make a paint mark on the head of each nut.
- Make a paint mark on the bolt end at the position 90 degree angle to 100 degree angle from the paint mark made on the nut in the direction of tightening the nut.
- Give a 90 degree angle to 100 degree angle turn to the nut and make sure that the paint mark on the nut and that on the bolt are in alignment.CAUTION:
- If the nut is turned less than 90 degree angle, proper fastening performance may not be expected. When tightening the nut, therefore, be careful to give a sufficient turn to it.
- If the nut is overtightened (exceeding 100 degree angle), loosen the nut completely and then retighten it by repeating the tightening procedure from step (1).
