TIMING CHAIN ASSEMBLY

Caution
• If the camshaft is rotated with the timing chain removed and the piston at the top dead center
position, the valve may contact the piston and the engine could be damaged. When rotating the
camshaft with the timing chain removed, rotate it after lowering the piston from the top dead
center position.
• When rotating the camshaft using a
wrench on the cast hexagon, the wrench
may contact the rocker arm and damage
the rocker arm. To prevent damage to the
rocker arm when holding the camshaft on
the cast hexagon, use a wrench on the
rear side of the engine as shown in the
figure to secure a clearance between the
cam.
Note
• Width at the cast hexagon of the camshaft is
22—24 mm {0.87—0.94 in}.
