Camshaft Assembly Note
1. Install the camshaft with No.1 cylinder aligned with TDC position.
2. Tighten the camshaft cap bolt using the following
two steps.
(1) Tighten to 5.0—9.0 N·m {51.0—91.7 kgf·cm,
44.3—79.5 in·lbf}.
(2) Tighten to 14.0—17.0 N·m {1.5—1.7 kgf·m,
10.4—12.5 ft·lbf}.
Camshaft Sprocket, Variable Valve Timing Actuator (L3 (with variable valve timing mechanism)) Assembly
Note
1. Camshaft sprocket or variable valve timing actuator (L3 (with variable valve timing mechanism)) attachment
bolt is changed into the state of a temporary bundle by hand until it attaches timing chain.
2. The attachment bolt of camshaft sprocket or variable valve timing actuator (L3 (with variable valve timing
mechanism)) is bound tight for timing chain after attachment.
Tightening torque
69—75 N·m {7.10—7.60 kgf·m, 50.9—55.3 ft·lbf}
