INSPECTION
Camshaft journal wear:
D 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 gaging plastic (1). The procedure is as
follows.
1) Clean housings and camshaft journals.
2) Make sure that all valve lash adjusters are removed and 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 housings as outlined on the following page and evenly
torque housing bolts to specified torque. Housings MUST be
torqued to specification in order to assure proper reading of
camshaft journal clearance.
NOTE:
Do not rotate camshaft while gaging plastic is installed.
5) Remove housing, and using scale (2) on gaging plastic envel-
op, measure gaging plastic width at its widest point.
