+Vacuum pipe
+Vacuum pump
2. Move the following parts.
+TDC sensor harness
+Power steering oil pump
3. Remove the chain cover.
+Remove the holding bolts A to C shown in the figure.
CAUTION:
While the chain cover is removed, be careful not to allow
entry of dust or foreign objects.
4. Set the No. 1 cylinder to the TDC.
1) Turn the crankshaft pulley clockwise, and match the timing
indicator of the gear case to the timing mark of the crankshaft
pulley.
2) Make sure that the cam sprocket match mark is in the posi-
tion shown in the figure.
+If the match mark is not in position, turn the crankshaft pul-
ley once more and position it.
+When removing at No. 1 cylinder TDC, each sprocket and
chain is fitted using the match mark, therefore there is no
need to apply any match marks beforehand.
5. Remove the chain tensioner.
1) Loosen upper and lower holding bolts.
2) Holding the chain tensioner in your hand, remove the upper
holding bolt and release the spring tension.
3) Remove the lower holding bolt, then remove the chain ten-
sioner.
+The chain tensioner does not have a mechanism which pre-
vents the ejection of the plunger. (It does have a mechanism
which prevents the plunger from returning.)
CAUTION:
Be careful not to drop the plunger and spring.

Inspection
+When the camshaft or parts in connection with valves are
removed or replaced, and a fault has occurred (poor starting,
idling, or other faults) due to the misadjustment of the valve
clearance, inspect as follows.
+Inspect and adjust when the engine is cool (at normal tem-
perature).
+Be careful of the intake and exhaust valve arrangement. (The
valve arrangement is different from that in a normal engine.)
(The camshafts have, alternately, either an intake valve or an
exhaust valve.)
1. Remove the following parts.
+Intercooler cover

+Rocker cover
2. Set the No. 1 cylinder at TDC.
1) Rotate the crankshaft pulley clockwise, and align the TDC
mark of the crankshaft pulley with the timing indicator of the
TDC sensor bracket.
2) Confirm that the cam nose of the No. 1 cylinder and the
knock pin of the cam sprocket is in the position shown in the
figure.
+Rotate the crankshaft pulley again if not in the position shown
in the figure.
3. While referring to the figure, measure the valve clearance in
the circled area of the table below.

4. Set the No. 4 cylinder at TDC by rotating the crankshaft
clockwise once.
