Р Replace the connecting rod bolts and nuts with new ones.

CAUTION:

Tighten the connecting rod bolts using the plastic-region tightening angle method. Always install new bolts and nuts.

С Clean the connecting rod bolts and nuts.

С Tighten the connecting rod nuts with speci-fied torque.

С Put a mark 1 on the corner of the connect-ing rod nut 2 and the connecting rod 3.

С Tighten the nut further to reach the speci-fied angle (90°).

WARNING

When the nut is tightened more than the specified angle, do not loosen the nut and then retighten it.

Replace the bolt with a new one and per-form the procedure again.

CAUTION:

Т Do not use a torque wrench to tighten the nut to the specified angle.

Т Tighten the nut until it is at the specified angles.

NOTE:

When using a hexagonal nut, note that the angle from one corner to another is 60°.

У Install:

balancer connecting rod

connecting rod cap

60 Nm (6.0 m · kg, 43 ft · lb)

CAUTION:

Х When tightening the nuts be sure to use an F-type torque wrench.

Х Without pausing, tighten to full torque specification. Apply continuous torque 57 ~ 63 Nm (5.7 ~ 6.3 m · kg, 41 ~ 45 ft · lb). Once you reach 57 Nm (5.7 m · kg, 41 ft · lb) DO NOT STOP TIGHTENING until final torque is reached. If the tightening is inter-rupted 57 ~ 63 Nm (5.7 ~ 6.3 m · kg, 41 ~ 45 ft · lb) loosen the nut to less than 57 Nm (5.7 m · kg, 41 ft · lb) and start again.

INSTALLING THE CRANKSHAFT

П Install:
