INSPECTION
Cam Wear
Using a micrometer, measure cam height “a”. If measured height
is below its limit, replace camshaft.
Cam height “a” of camshaft
Camshaft Runout
Set camshaft between two “V” blocks, and measure its runout by
using a dial gauge.
If measured runout exceeds below limit, replace camshaft.
Camshaft runout limit
: 0.10 mm (0.0039 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 hous-
ings.
Check clearance by using gaging plastic. Checking procedure is
as follows.
1) Clean housings and camshaft journals.
2) Remove all tappets with shims.
3) Install camshafts to cylinder head.
4) Place a piece of gaging plastic to full width of journal of cam-
shaft (parallel to camshaft).
5) Install camshaft housing.

figure a little at a time till they are tightened to specified
torque.
Tightening torque

7) Remove housing, and using scale (2) on gaging plastic (1)
envelop, measure gaging plastic width at its widest point.
Camshaft journal clearance
If measured camshaft journal clearance exceeds limit, measure
journal (housing) bore and outside diameter of camshaft journal.
Replace camshaft or cylinder head assembly whichever the differ-
ence from specification is greater.

Wear of tappet and shim
Check tappet and shim for pitting, scratches or damage.
If any malcondition is found, replace.
Measure cylinder head bore and tappet outside diameter to deter-
mine cylinder head-to-tappet clearance. If clearance exceeds
limit, replace tappet or cylinder head.

INSTALLATION
1) Install tappets and shims to cylinder head.
Apply engine oil around tappet and then install it to cylinder
head.
2) Install camshafts (1).
Apply engine oil to sliding surface of each camshaft and camshaft
journal then install them as shown in figure.
NOTE:
When installing shim, make sure to direct shim No. side
toward tappet.
NOTE:
Before installing camshafts, turn crankshaft until key
position faces upward. Refer to “TIMING CHAIN AND
CHAIN TENSIONER”.

3) Install camshaft housing pins (1) as shown in figure.
4) Check position of camshaft housings.
Embossed marks are provided on each camshaft housing,
indicating position and direction for installation. Install hous-
ings as indicated by these marks.
5) After applying engine oil to housing bolts, tighten them tem-
porarily first. Then tighten them by the following numerical
order in figure. Tighten a little at a time and evenly among
bolts and repeat tightening sequence two or three times
before they are tightened to specified torque.
