+Move power steering fluid reservoir tank from the bracket.
+Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
+Remove No. 6, 10, and 11 bolts with the rubber washer as
space is limited for pulling them out.

+While front chain case is removed, cover openings to pre-
vent entry of foreign material into engine.
+Do not remove two mass dampers on the back of cover.

4. Set the No. 1 piston to TDC on its compression stroke.
+Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
+No position indicator is provided on the crankshaft pulley.
+When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
injection pump sprocket may not be easy to see.

specification. They will be used later to determine the required
replacement adjusting shim.
Valve clearance for checking (Cold):
Intake

1. Turn crankshaft, to position cam lobe on camshaft of valve that
must be adjusted upward.
2. Place Tool (A) around camshaft as shown in figure.
Before placing Tool (A) (SST), rotate notch toward center
