Camshaft Runout
Set camshaft between two "V" blocks, and measure its
runout by using a dial gauge.
If measured runout exceeds the specified limit, replace
camshaft.
Runout limit
0.03 mm (0.0012 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for
pitting, scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder
head with housing. Never replace cylinder head without
replacing housings.
Check clearance by using gauging plastic. Checking
procedure is as follows.
1) Clean housings and camshaft journals.
2) Make sure that all tappets with shims are removed
and install camshafts to cylinder head.
3) Place a piece of gauging plastic to full width of
journal of camshaft (parallel to camshaft).
4) Install camshaft housing.
5) Tighten camshaft housing bolts in such order as
indicated in figure a little at a time till they are
tightened to specified torque.
NOTE
Do not rotate camshaft while gauging plastic
is installed.
