13) Remove the idler sprocket (upper).
14) Remove the timing chain (LH).
15) Remove the idler sprocket (lower).
B: INSTALLATION
NOTE:
•Be careful that the foreign matter is not into or
onto assembled component during installation.
•Apply engine oil to the chain guide, chain ten-
sioner lever and idler sprocket when installing.
1) Preparation for chain tensioner installation
(1) Insert the screw, spring pin and tension rod
into tensioner body.
(2) While depressing the tensioner onto rubber
mat, twist it to shorten tension rod. Then insert
the thin pin into the hole between tension rod
and tension body to keep it.
NOTE:
Work on the rubber mat or other anti-skid materials.
2) Using the ST, align the “Top mark” on crank
sprocket to 9 o’clock position as shown in the figure
ST 18252AA000 CRANKSHAFT SOCKET
3) Align the key groove on exhaust cam sprocket to
12 o’clock position as shown in the figure.
