\u2022 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.<\/div>\n
\u2022 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 the wrench at engine rear side as shown in the figure to secure a clearance between the cam.<\/p>\n\n\n\n

Chain Tensioner Removal Note (Chain tensioner (type A))<\/p>\n

1.While moving the exhaust camshaft back and forth in the direction of the arrow using a wrench on the cast hexagon, press down the link plate of the timing chain tensioner using a precision screwdriver and release the plunger lock.<\/p>\n

Note<\/div>\n<\/dd>\n
\n
\u2022 When moving the exhaust camshaft back and forth, the timing chain pushes the plunger in the chain tensioner making it easier to operate the link plate.<\/div>\n<\/dd>\n<\/dl>\n

2.Push back the plunger slowly in the direction shown in the figure with the link plate still pushed down.<\/p>\n

3.Remove the screwdriver from the link plate with the plunger still pushed down.<\/p>\n

\n

4.Release the force slightly from the plunger, and move it back and forth 2\u20143 mm {0.08\u20140.11 in}<\/span>.<\/p>\n

\n

5.Insert a wire with an approx. diameter of 1.5 mm {0.059 in}<\/span> or a paper clip where the link plate hole and the tensioner body hole overlap to secure the link plate and lock the plunger.<\/p>\n

Chain Tensioner Removal Note (Chain tensioner (type B))<\/p>\n

1.Insert a metal rod (diameter approx. 1.4 mm {0.055 in}<\/span>, length approx. 55 mm {2.16 in}<\/span>) into the hole in the body of the chain tensioner.<\/p>\n

\u2022 The rod secures the plunger and releases the tension.<\/div>\n<\/dd>\n<\/dl>\n

5.Loosen the power of the hand pressing the plunger and verify that the pressed-in rod does not move.<\/p>\n
