INSPECTION
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 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.

ever the difference from specification is greater.

As camshaft housing No.1 (1) retains camshaft in proper
position as to thrust direction, make sure to first fit No.1 hous-
ing to No.1 journal of camshaft securely.

After applying engine oil to housing bolts, tighten them tem-
porarily first. Then tighten them by following sequence as
shown in figure.
Tighten a little at a time and evenly among bolts and repeat
tightening sequence three to four times before they are tight-
ened to specified torque.

INSPECTION
Valve Guides
Using a micrometer and bore gauge, take diameter readings on
valve stems and guides to check stem-to-guide clearance.
Be sure to take reading at more than one place along the length of
each stem and guide.
If clearance exceeds limit, replace valve and valve guide.

INSTALLATION
NOTE:

All parts to be installed must be perfectly clean.

Be sure to oil crankshaft journals, journal bearings, thrust
bearings, crankpins, connecting rod bearings, pistons, pis-
ton rings and cylinder bores.

Journal bearings, bearing caps, connecting rods, rod bear-
ings, rod bearing caps, pistons and piston rings are in com-
bination sets. Do not disturb combination and try to see that
each part goes back to where it came from, when installing.
1) Fit main bearings to cylinder block (1).
Among two halves of main bearing, one halt has oil groove (3).
Install this half with oil groove to cylinder block, and another half
without oil groove to bearing cap.
Make sure that two halves are painted in the same color.
2) Fit thrust bearings (1) to cylinder block between No.2 and No.3
cylinders. Face oil groove (2) sides to crank webs.
3) Put crankshaft on cylinder block.
4) Fit bearing caps sequentially in ascending order, 1, 2, 3 and 4,
starting from pulley side. Be sure to point arrow mark (2) (on
each cap) to crankshaft pulley side (1).
Gradual and uniform tightening is important for bearing cap
bolts. Make sure that four caps become tight equally and pro-
gressively till specified torque is attained.

.m (5.3 kg-m, 38.5 lb-ft)
NOTE:
After tightening cap bolts, check to be sure that crankshaft
rotates smoothly when turned by hand.
