VALVE
ADJUSTMENT

Proper
valve adjustment is important to prevent
burning
of valves and poor
engine
performance.

This
adjustment consists of obtaining a specified

lash
in the valve mechanism. The exhaust valve
tappets and the intake valve rocker arms should be adjusted to the proper clearance with the
engine

cold (at room temperature). Valve clearance can
be properly adjusted only when the tappet is on the
heel or low portion of the cam.

TIMING
D-108. Valve Adjustment Procedure

The
exhaust valve tappets are adjusted by turning
the adjusting screw in or out of the tappet as neces­
sary
to obtain the proper clearance. Where special
wrenches can be obtained, they should be used to facilitate the adjustment. The proper clearance is .016" [0,406 mm.]
between
the end of the adjusting
screw and the
bottom
of the exhaust valve.

Crank
the
engine
over to
close
a valve and check
the clearance with a feeler
gauge.
To adjust, hold
the tappet with one wrench and
turn
the adjusting

screw,
with the other.
Check
and adjust each of
the tappets in proper sequence.

Adjust
each intake valve by adjusting the rocker
arm
screw at the push rod to obtain .018" [0,457 mm.] clearance
between
the rocker arm and the
valve stem with tappet on the heel of the cam.
D-109.
Check
Valve
Timing

To
check the valve timing, carefully set the intake
valve rocker arm adjustment for No. 1 cylinder to .026"
[0,6604
mm.]
between
the rocker arm and the
valve stem. Rotate the crankshaft clockwise until
the piston in No. 1 cylinder is ready for the intake stroke. The intake valve
opens
9° before top center
(BTC).
Note
the distance
between
the
"TC"
and
"5°"
marks on the indicator on the timing gear
cover and estimate the 9° before top center position.
See
Fig.
D-43.
With
the crankshaft in this position, timing is correct if the rocker arm is just tight
against the intake valve stem. Do not overlook resetting the rocker arm adjustment to the correct

running
clearance.
D-110. Positive
Crankcase
Ventilation

Be
sure there are no air leaks at the tube connec­
tions
between
the air cleaner and the oil filler tube,

and
that the oil filler tube cap gasket is in
good

condition. Always keep the cap locked securely in
place. When tuning the
engine
or grinding valves, remove the control valve and clean it thoroughly.
If
the valve is blocked with carbon, the ventilating
system
will
not operate and, should the valve

fail
to seat, it
will
be impossible to make the
engine

idle satisfactorily. Refer to Par. C-6 for servicing.
D-111. Oil
Filter

The
engine
is equipped with a throw-away type

oil
filter.
This
oil filter must be serviced periodi­
cally
as outlined in the

Belt matic adjuster, to prevent lash in the valve operat­
ing linkage. Hydraulic valve lifters also provide

a
cushion of oil to absorb operating shocks. As shown in Fig. Dl-3, all parts of a hydraulic lifter

are
housed in the body, which is the cam follower.

At
the beginning of valve operation, the valve lifter body rests on the camshaft base circle.

Plunger
spring tension prevents lash clearances in the valve linkage.

As
the camshaft forces the valve lifter body up­

ward,
both oil in the lower chamber and check

ball
spring
tension firmly seat the check ball against the plunger to prevent appreciable
loss
of oil from
the lower chamber. Oil pressure forces the plunger
upward,
with the body, to operate the valve linkage.

As
the camshaft rotates to closed-valve position, the valve spring forces the linkage and lifter down­

ward.
When the
engine
valve seats, the linkage

parts
and plunger stop, but the plunger spring forces
the body downward .002" to .003"
[0,050
a
0,076
mm.] until it again rests on the camshaft base

circle.
Oil pressure then forces the check ball away

from
its seat and allows passage of oil past the check ball into the lower chamber.
This
replaces
the slight amount of oil lost by leakage. During
the valve opening and closing operation, a very
slight amount of oil escapes
between
plunger and body, and returns to the crankcase.
This
slight
loss
of oil (leak-down) is beneficial. It provides a
gradual
change of oil in the valve lifter; fresh oil
enters the lower chamber at the end of each cycle
of operation. 77

ENGINE
In
addition to the instructions covering operations
for disassembling the
engine
out of the vehicle, special instructions are given to cover different
operations required when disassembly is
done
with
the
engine
installed.

During
disassembly operations, the
engine
should be mounted in a suitable
engine
repair stand.

Where
practicable, modify or adapt an existing re­

pair
stand as necessary to accommodate the
engine.
If
an
engine
repair stand is not used, take care to

perform
disassembly operations in a manner that
will
protect personnel against an accident and the
engine
and its parts against damage.

Refer
to Fig. Dl-4.
a.
With
the
engine
supported by a hoist, remove
the clutch housing and clutch. Match
mark
the flywheel and the clutch cover before disassembly to assure proper reassembly.
b. Position the
engine
on the
engine
stand.
c. Release
some
tension of the hoist cables and secure
engine
to stand.

d.
Make sure the position lock on the

is tight to prevent the
engine
from accidentally
inverting.
