INSPECTION
(1) Inspect camshaft bearing journals for damage
and binding (Fig. 27). If journals are binding, check
the cylinder head for damage. Also check cylinder
head oil holes for clogging.
(2) Inspect camshaft sprockets for excessive wear.
Replace camshafts if necessary.

(3) Check the cam lobe surfaces for abnormal wear
and damage. Replace camshaft if defective. Measure
the actual wear (Fig. 27)and replace, if out of lim-
its—standard value is 0.0254 mm (0.001 in.); wear
lim it is 0.254 mm (0.010 in.).
INSTALLATION
CAUTION: When the timing chain is removed and
the cylinder heads are installed, DO NOT rotate the
camshafts or crankshaft without first locating the
proper crankshaft position. Failure to do so will
result in valve and/or piston damage.
(1) Assemble camshaft chain on the cams. Ensure
that plated links are facing toward the front. Align
the plated links to the dot on the camshaft sprockets
(Fig. 29).
(2) If camshaft chain tensioner is already in the
compressed and locked position, proceed to step (4).
(3) When the camshaft chain tensioner is removed,
it is necessary to compress and lock the tensioner
using the following procedures:
(a) Place tensioner into a soft jaw vise (Fig. 28).
