Loosen the adjusting screws.
Remove the camshaft holders.
Mark the rocker arms, then remove them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.
9.8 N.m (1.0 kgf.m.7.2 lbf.ft)
Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft, push the camshaft back and forth and
read the end play.
Camshaft End Play:

Service Limit: 0.5 mm (0.02 in)
Unscrew the camshaft holder bolts two turns at a
time, in a crisscross pattern, Then remove the
camshaft holder bolts from the cvlinder head.
Lift the camshafts out of the cylinder head. wipe
them clean, then inspect the lift ramps, Replace the
camshaft if any lobes are pitted, scored, or exces-
sively worn.
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in Dlace. Place aplastigage strip across each journal.
Install the camshaft holders. and torque the bolts tothe values and in the sequence shown on page 6-31.
NOTE: Do not rotate the camshafts during inspection.

12. lf camshaft-to-holder oil clearance is out of toler-
ance:
. And the camshaft has already been replaced,
you must replace the cylinder head.. lf the camshaft has not been replaced, first check
total runout with the camshaft suoDorted on V-
blocks.
Camshaft Total Runout:
Standard (N6w): 0.03 mm (0.001 in) max.
Service Limit 0.04 mm (0.(X)2 in)
Rotat6 camshattwhile measuring.
- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance, replace the cylinder head.

Cylinder Head
Installation
Installthe cylinder head in the reverse order of removal:
1. Clean the cylinder head and block surfaces.
2. Clean the oil control orifice. Install the cylinder headgasket, dowel pins and the oil control orifice on thecylinder block. Always use a new cylinder head gas-ket.

OIL CONTBOLORIFICEClean.
Apply clean engine oil to the bolt threads and underthe bolt heads.
4. Tighten the cylinder head bolts in two steps. In thefirst step tighten all bolts, in sequence, to about 29
N.m {3.0 kgf.m,22 lbf.ft); in the finat step, tighten inthe same sequence to 85 N.m (8.7 kgf.m,63 lbf.ft).
Use a beam-type torque wrench. When using a pre-
set-type torque wrench, be sure to tighten slowly
and do not overtighten.
lf a bolt makes any noise while you are torquing it,loosen the bolt, and retighten it from the 1st step.
CYLINDER HEAD BOLTS TOROUE SEOUENCE:
Tighten the intake manifold mounting bolts (see
page 6-21).
Install the exhaust manifold bracket. and tighten thenew self-locking nuts (see page 6-20).

1. Apply a coat of engine oil to the ring grooves andcylinder bores.
It the crankshaft is already installed.
2. Set the crankshatt to BDC for each cylinder.3. Remove the connecting rod caps, and slip short sections of rubber hose over the threaded ends of theconnecting rod bolts.
4. lnstall the ring compressor, and check that the bear-ang is securely in place.
5. Position the piston in the cylinder, and tap it in usingthe wooden handle of a hammer. Maintain down-ward force on the ring compressor to prevent ringstrom expanding before entering the cylinder bore.6. Stop after the ring compressor pops free, and checkthe connecting rod-to-crank journal alignmentbefore pushing piston into place.

Some filters have eight numbers (1 to 8) printed on
the surface of the filter.
The following explains the procedure for tightening
filters using these numbers.
l) Make a mark on the cylinder block under the num-
ber that shows at the bottom of the filter when the
rubber seal is seated.
2) Tighten the filter by turning it clockwise seven
numbers from the makes point. For example, if a
mark is made under the number 2 when the rub-
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point.
Number when rubberseal is seated.Number af ter tightening.
5.After installation. fill the engine with oil up to the
specified level, run the engine for more than threeminutes, then check for oil leakage and oil level.
GAUTION: Installation using other than the aboveprocedure could result in serious engine damage
due to oil leakage.
