Check clearance by using gaging plastic.
The procedure is as follows.
1) Clean housings and camshaft journals.
2) Install camshaft to cylinder head.
3) Place a piece of gaging plastic the full width of journal of cam-
shaft (parallel to camshaft).
4) Install camshaft housing, referring to INSTALLATION of follow-
ing page.
5) Tighten camshaft housing bolts in such order as indicated in fig-
ure a little at a time till they are tightened to specified torque.
Tightening Torque
(a): 11 N
.
m (1.1 kg-m, 8.0 lb-ft)
NOTE:
Do not rotate camshaft while gaging plastic is installed.
6) Remove housing and using scale (2) on gaging plastic enve-
lope, measure gaging plastic (1) width at its widest point.
If measured camshaft journal clearance exceeds limit, measure
journal (housing) bore and outside diameter of camshaft jour-
nal. Replace camshaft or cylinder head assembly whichever
the difference from specification is greater.
