5. Set the No.1 cylinder at TDC on its compression stroke using
the following procedure:
a. Rotate crankshaft pulley clockwise, and align mating mark for
TDC (B) with timing indicator (A) on front cover, as shown.
NOTE:
Do not use the white paint mark (C).
b. At the same time, make sure that the mating marks (outer
groove) (B) on camshaft sprockets are lined up with the pink
links (A) in the timing chain, as shown.
• If not, rotate crankshaft pulley one more turn to line up the
mating marks (outer groove) (B) to the pink links (A), as
shown.
NOTE:
Shown with front cover removed for illustration purposes only.
6. Remove chain tensioner (1) and timing chain using the following procedure:
a. Pull the lever (B) down and release the plunger stopper tab (C).
• Plunger stopper tab (C) can be pushed up to release (coaxial
structure with lever (B)).
b. Insert the stopper pin (A) into the tensioner body hole to hold the
lever (B) and keep tab released.
NOTE:
Allen wrench [2.5 mm (0.098)] is used for a stopper pin as an
example.
c.
Insert plunger (C) into tensioner body by pressing timing chain
slack guide (1).
d. Keep timing chain slack (1) guide pressed and hold it by pushing
the stopper pin (B) through the lever hole and body hole.
e. Remove the chain tensioner bolts (A) and chain tensioner.
f.
Remove the timing chain from camshaft sprocket (INT) and camshaft sprocket (EXH).
CAUTION:
• Use suitable tool to prevent timing chain from falling into front cover after it has been removed
from camshaft sprocket (INT) and camshaft sprocket (EXH).
• Do not rotate the crankshaft or camshafts while the timing chain is removed. It can cause dam-
age to the valves and pistons.

7. Remove the camshaft sprockets using the following procedure:
a. Secure hexagonal part of the camshaft with a suitable tool and
loosen the camshaft sprocket bolt.
b. Remove the camshaft sprocket bolt and camshaft sprockets for
both camshafts.
8. Loosen the camshaft bracket bolts in the order as shown, and
remove the camshaft brackets and camshafts.
NOTE:
Remove camshaft bracket (No. 1) by slightly tapping it with a
rubber mallet.
9. Remove the valve lifters.
NOTE:
Check installation positions, and set them aside in the order removed.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put the camshaft on a V-block supporting the No.2 and No.5
journals.
CAUTION:
Do not support the No. 1 journal (on the side of the cam-
shaft sprocket) because it has different diameter from the
other four locations.
2. Set suitable tool (A) vertically on the No.3 journal.
3. Turn camshaft in one direction by hand, and measure the cam-
shaft runout on the dial gauge total indicator reading.
Camshaft Cam Height
1. Measure the camshaft cam height using suitable tool (A).
2. If wear is beyond the limit, replace the camshaft.

CAMSHAFT
• Measure the outer diameter of the camshaft journal using suitable
tool (A).
Inner Diameter of Camshaft Bracket
• Tighten the camshaft bracket bolts to the specified torque following
the tightening pattern as shown.
• Using suitable tool (A), measure inner diameter of camshaft
bracket (1).
Calculation of Camshaft Journal Clearance
• (Journal clearance) = (inner diameter of camshaft bracket) – (outer diameter of camshaft journal)
• When out of the specified range above, replace either or both the camshaft and the cylinder head assembly.
NOTE:
Inner diameter of the camshaft bracket is manufactured together with the cylinder head. If the camshaft
bracket is out of specification, replace the whole cylinder head assembly.
