a.
Install them by aligning the mating marks
on each camshaft
sprocket with the ones painted on timing chain link plate during
removal.
CAUTION:
• Aligned mating marks could slip. Therefore, after match-
ing them, hold the timing chain in place by hand.
• Before and after installing chain tensioner, check again
that mating marks have not slipped.
NOTE:
Before installation of chain tensioner, it is possible to re-match the marks on timing chain with the ones on
each sprocket.
b.
Tighten bolts in the following steps.
• Secure the hexagonal part of camshaft using wrench to tighten mounting bolt.
i.
Tighten camshaft mounting bolt.
ii.
Turn 45 degrees clockwise (angle tightening).
CAUTION:
Check the tightening angle by using an angle wrench [SST:
KV10112100](B) or protractor. Never judge by visual inspec-
tion without an angle wrench.
6.
Install chain tensioner.
CAUTION:
After installation, pull the stopper pin off completely, and check that chain tensioner plunger is

INSPECTION AFTER REMOVAL
Camshaft Runout
1.
Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2.
Set dial indicator (A) vertically to No. 3 journal.
3.
Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)
4.
If out of the standard, replace camshaft.
Camshaft Cam Height
1.
Measure the camshaft cam height with a micrometer (A).
2.
If it exceeds the limit, replace camshaft.
