(5) Using several steps, loosen and remove the 8 bearing cap bolts uniformly in the sequence as shown in the illustration.
(6) Remove the 4 bearing caps and No.2 camshaft.
d. Remove the chain tensioner No.2.
(1) Remove the chain tensioner No.2 bolt, and then remove the chain tensioner No.2 and camshaft timing sprocket.
e. Remove the camshaft.
NOTICE: As the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not
kept level, the portion of the cylinder head which receives the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To
avoid this, the following steps should be carried out.
(1) Hold the hexagonal portion of the No.1 camshaft with a wrench, and loosen the camshaft timing gear assembly set bolt.
NOTICE:
-
Be careful not to damage the cylinder head and valve lifter with the wrench.
-
Do not disassemble the camshaft timing gear assembly.
(2) Slide the camshaft timing gear assembly and separate the No.1 chain from the camshaft timing gear sprocket.
