(g) Tie the No. 1 chain with a piece of string as shown in the illustration.
NOTICE: Be careful not to drop anything inside the timing chain cover.
18. REMOVE NO. 4 CAMSHAFT SUB-ASSEMBLY
NOTICE: Keep the camshaft level while it is being removed. The camshaft thrust clearance is very small and failing to keep it level could crack
or damage the cylinder head journal surface, which receives the thrust force. This could subsequently lead the camshaft to seize or break. Perform
the following steps to avoid such problems.
(a)
While pushing down the No. 3 chain tensioner, insert a pin of diameter 1.0 mm (0.039 in.) into the hole to fix it.
(b) Hold the hexagonal portion of the No. 4 camshaft with a wrench, and remove the camshaft timing gear set bolt.
NOTICE: Be careful not to damage the cylinder head or valve lifter with the wrench.
(c)
Separate the camshaft timing gear from the No. 4 camshaft.
