18 - Cooling System Pressure Test

Carburetor

Refer to Section 6M to perform adjustments such as

idle vent, float level, pump rod and secondary valve.

Fuel Pump

If the owner has complained of poor high speed per-

formance, the fuel pump may be at fault. Too low a

pump pressure or volume will cause a high speed "miss"

because of lack of fuel delievered to the carburetor,

while too high a pressure will cause carburetor flooding.

Check fuel pump as outlined in Section 6M.

Cooling System

The following test may be performed with pressure

testing equipment available commercially for this pur-

pose.
This test provides an excellent means of detecting

internal or external leaks within the cooling system.

1.
Remove radiator cap.

2.
Apply a test pressure of 3 pounds higher than the ra-

diator cap (fig. 18). i.e. 18 pounds for a 15 pound

cap.

3.
If the pressure will not hold, there is either an

internal or external leak in the system.

Cylinder Head Torque and Valve Adjustment

Retorquing the cylinder head bolts is not necessary

unless a gasket has been replaced, or a leak is suspected.

Valve lash must always be adjusted after the head has

been torqued.

Before adjusting the valve lash, it is extremely impor-

tant that the engine be thoroughly warmed up to normal-

ize the expansion of all parts. This is very important

because during the warm-up period, the valve clearances

will change considerably.

Hydraulic

1.
After the engine has been normalized, remove rocker

arm covers and gaskets.

CAUTION: Do not pry rocker arm cover loose.
Gaskets adhering to cylinder head and rocker

arm cover may be sheared by bumping end of

rocker arm cover rearward with palm of hand

or a rubber mallet.

2.
With the engine running at idle, back off valve rocker

arm nut until the valve rocker arm starts to clatter.

3.
Turn rocker arm nut down slowly until the clatter

just stops. This is the zero lash position.

4.
Turn nut down 1/4 additional turn and pause 10 sec-

onds until engine runs smoothly* Repeat additional

1/4 turns, pausing 10 seconds each time, until nut

has been turned down 1 full turn from the zero lash

position.

NOTE: This 1 turn preload adjustment must be

done slowly to allow the lifter to adjust itself to

prevent the possibility of interference, between

the inlet valve head and top of piston, which

might result in internal damage and/or bent push

rods.
Noisy lifters should be replaced.

5.
Repeat Steps 2, 3 and 4 to adjust the rest of the

valves.

6. Clean gasket surfaces on cylinder heads and rocker

arm covers with degreaser then install rocker arm

covers, using new gaskets, and torque bolts to

specifications.

Mechanical

1.
Normalize the engine.

2.
Remove rocker arm covers and gaskets.

CAUTION: Do not pry rocker arm cover loose.

Gaskets adhering to cylinder head and rocker

arm cover may be sheared by bumping end of

rocker arm cover rearward with palm of hand

or a rubber mallet.

3.
Use a socket wrench on self-locking rocker arm stud

nut and adjust as needed to obtain valve lash (see

tune up chart) measured between rocker arm and

valve stem with a leaf type feeler gauge.

4.
Stop engine, clean gasket surfaces on cylinder heads

and rocker arm covers with degreaser then install

rocker arm covers, using new gaskets, and torque

bolts to specifications.

GENERAL DESCRIPTION

The function of the starting system, composed of the

starting motor, solenoid and battery, is to crank the

engine. The battery supplies the electrical energy, the

solenoid completes the circuit to the starting motor, and

the motor then does the actual work of cranking the

engine.

The starting motor (fig. Is) consists primarily of the

drive mechanism, frame, armature, brushes, and field

windings. The starting motor is a pad mounted 12-volt

extruded frame type, having four pole shoes and four
fields,
connected with the armature. The aluminum drive

end housing is extended to enclose the entire shift lever

and plunger mechanism, protecting them from dirt,

splash, and icing. The flange mounted solenoid switch

operates the overrunning clutch drive by means of a

linkage to the shaft lever.

The V-8 wiring harness differs from the in-line engine

in that the ignition lead to the coil from the switch is at-

tached at the coil instead of at the starter solenoid (fig.

2s).

MAINTENANCE AND ADJUSTMENTS

No periodic lubrication of the starting motor or sole-

noid is required. Since the starting motor and brushes

cannot be inspected without disassembling the unit, no.

service is required on these units between overhaul

periods.

RESISTANCE CHECKS

Although the starting motor cannot be checked against
specifications on the car, a check can be made for. exces-

sive resistance in the starting circuit. Place a volt-

meter across points in the cranking circuit as outlined

below and observe the reading with the starting switch

closed and the motor cranking (distributor primary lead

grounded to prevent engine firing).

OTHER SERVICE OPERATIONS

Although certain operations, such as oil pan or gasket

replacement, valve body, governor, filler pipe "O" ring,

speedometer drive gear, case extension "0" ring and

rear oil seal, vacuum modulator, and servo cover or

gasket service may be performed from underneath the
vehicle without removing the Powerglide; their service

procedure is covered in the Passenger Overhaul Manual

and is not repeated here. Refer to the- Powerglide Sec-

tion of the Passenger Overhaul Manual for all other

service operations not covered here.

DIAGNOSIS

Proper operation of the Powerglide transmission may

be affected by a number of factors, all of which must be

considered when trouble in the unit is diagnosed.

Proper trouble diagnosis can only be accomplished

when performed in a thorough step by step procedure.

The following procedure has been devised and tested and

is recommended for all trouble diagnosis complaints and

if the service man will follow this checking procedure,

accurate and dependable diagnosis may be accomplished.

This will result in a savings of time, not only to the

service man, but to the customer as well.

WARMING UP TRANSMISSION

Before attempting to check and/or correct any com-

plaints on the Powerglide transmission it is absolutely

essential that the oil level be checked and corrected if

necessary. An oil level which is either too high or too

low can be the cause of a number of abnormal conditions

from excessive noise to slippage in all ranges.

It must be remembered that cold oil will slow up the

action of the hydraulic controls in the transmission. For

this reason a trouble or oil leak diagnosis should not be

attempted until the transmission has been warmed up by

either of the following procedures:

Shop Warm Up

1.
Connect tachometer to engine.

2.
Set parking brake tight and start engine.

3.
Place selector light in
"D"
(drive) range.

4.
Adjust carburetor idle speed adjusting screw to run

engine at approximately 750 rpm and operate in this

manner for two minutes. At the end of two minutes

of operation, the transmission will be sufficiently

warmed up for diagnosis purposes.
NOTE:
At this point, readjust the engine idle

speed to 450-475 rpm in
"D"
range.

Road Warm Up

Drive the car approximately 5 miles with frequent

starts and stops.

NOTE:
At this point, make sure the engine idle

speed is set to 450-475 rpm in
"D"
range.

CHECKING FLUID LEVEL AND CONDITION

After transmission has been warmed up, check the

fluid level with the engine idling, parking brake set and

control lever in "N" (neutral). If the fluid level is low,

add fluid to bring level up to the full mark on gauge rod,

CAUTION: If fluid level is too high, fluid may

be aerated by the planet carrier. Aerated fluid

will cause turbulence in the converter which will

result in lost power, lower stall speed and lower

pressures in control circuits. Lower fluid level

to full mark, then shut off engine to allow air

bubbles to work out of fluid.

When checking oil level, aburned smell and discolora-

tion indicate burned clutches or bands and the transmis-

sion will have to be removed.

MANUAL LINKAGE

Manual linkage adjustment and the associated neutral

safety switch are important from a safety standpoint.

The neutral safety switch should be adjusted so that the

engine will start in the Park and Neutral positions only.

With the selector lever in the Park position, the park-

ing pawl should freely engage and prevent the vehicle

CHEVROLET CHASSIS SERVICE MANUAL

CLUTCH AND TRANSMISSIONS 7-37

LI.
- LI Range can be selected at any vehicle speed,

and the transmission will shift to second gear

and remain in second until vehicle speed is re-

duced to approximately 40 MPH, .depending on

axle ratio. LI Range position prevents the trans-

mission from shifting out of first gear.
It is very important that any communication concerning

the Turbo Hydra-Matic always contain the transmission

serial number and that all transmission parts returned

to Chevrolet Motor Division always be tagged with the

transmission serial number.

MAINTENANCE AND ADJUSTMENTS

TRANSMISSION FLUID

Transmission fluid level should be checked with trans-

mission warm and selector lever in "P" Park position,

every time engine oil level is checked or as specified in

Section 0 when engine oil is changed.

CAUTION: Since the Turbo Hydra-Matic trans-

mission is very sensitive to oil level, special

precautions should be taken when checking the

oil level, to insure against an overfifE

Transmission fluid should be changed as specified in

Section 0.

FLUID LEVEL INDICATOR

The fluid level indicator is located in the filler pipe at

the right rear corner of the engine. To bring the fluid

level from the add mark to the full mark add 1 pint.

Fluid level should be to the full mark with transmission

at normal operating temperature. With cold fluid the

level should be at the add mark or slightly below.

SHIFT CONTROL LINKAGE ADJUSTMENT

Adjust linkage as shown below and in Figure 2.

1.
The shift tube and lever assembly must be free in the

mast jacket See Section 9 for alignment of steering

column assembly if necessary.

2.
To check for proper shift linkage adjustment, lift the

transmission selector lever towards the steering

wheel. Allow the selector lever to be positioned in

drive (D) by the transmission detent.

NOTE: Do not use the indicator pointer as a

reference to position the selector lever. When

performing linkage adjustment, pointer is ad-

justed last.

3.
Release the selector lever. The lever should be in-

hibited from engaging low range unless the lever is

lifted.

4.
Lift the selector lever towards the steering wheel,

and allow the lever to be positioned in neutral (N) by

the transmission detent.

5.
Release the selector lever. The lever should now be

inhibited from engaging reverse range unless the

lever is lifted.

6. A properly adjusted linkage will prevent the selector

lever from moving beyond both the neutral detent,

and the drive detent unless the lever is lifted to pass

over the mechanical stop in the steering column.

See schematic diagram.

7.
In the event that an adjustment is required, place the

selector lever in drive (D) position as determined by

the transmission detent. See Steps 2 and 3.

8. Loosen the adjustment swivel at the cross-shaft, and
rotate the transmission lever so that it contacts the

drive stop in the steering column.

9. Tighten the swivel and recheck the adjustment. See

Steps 2 and 6. -

l(h Readjust indicator needle if necessary to agree with

the transmission detent" positions. See Section 9.

11.
Readjust neutral safety switch if necessary to pro-

vide the correct relationship to the transmission de-

tent positions. See Section 12.

12.
When properly adjusted the following conditions must

be met by manual operation of the steering column

shift lever:

a. From reverse to drive position travel, the trans-

mission detent feel must be noted and related to

indicated position on dial.

b.
When in drive and reverse positions, pull lever

rearward (towards steering wheel) and then re-

lease. It must drop back into position with no

restrictions.

NEUTRAL SAFETY SWITCH ADJUSTMENT

The neutral safety switch must be adjusted so that the

car will start in the park or neutral position, but will not

start in the other positions. For replacement refer to

Section 12 of this Manual.

DRAINING AND REFILLING TRANSMISSION

Drain oil immediately after operation before it has had

an opportunity to cool.

To drain oil proceed as follows:

1.
Remove bottom pan attaching screws, pan, and gas-

ket.

2.
Remove oil strainer. Remove "O" ring seal from

pick-up pipe and discard.

3.
Discard strainer if dirty.

4.
Install new "O" ring seal on pick-up pipe and install

strainer and pipe assembly.

5.
Thoroughly clean bottom pan.

6.. Affix new gasket to bottom pan with petroleum jelly.

7.
Install bottom pan with attaching screws and torque

to specifications;

8. If only the pan has been removed, pour approximately

7-1/2 pints of fluid into the transmission. If the

valve body has also been removed use 9-1/2 pints.

After a complete overhaul approximately 19 pints

are required. Be sure container, spout, or funnel is

clean.

9. Start engine and let idle (carburetor off fast idle

step).
Place selector lever in P position and apply

hand brake.

10.
With transmission warm (approximately 150°F), add

fluid to bring level to full mark on indicator.

CAUTION: Do not overfill. Foaming will re-

sult.

GENERAL DESCRIPTION

Two types
of
power steering
are
used
for 1967.
One
is

the conventional linkage type
for
Chevy
n and
Corvette

vehicles
and the
other
is the
integral gear type
for

Chevrolet, Chevelle,
and
Camaro.
For
both types
the

hydraulic pressure
is
provided
by an
engine-driven vane-

type pump.

On
the
Chevy
n and
Corvette linkage type power steer-

ing, hydraulic pressure
is
delivered through
a
hose from

the pump
to a
valve which senses
the
requirement
for

power assistance
and
supplies
the
power cylinder
ac-

cordingly.
The
steering gear used with this power steer-

ing
is the
same basic unit used
on
manually steered

vehicles;
it is
serviced
as
outlined
in the
manual steering

part
of
this section except
for
adjustment, which
is

covered
in the
following pages.
The
steering linkage also

is serviced the same
as
manual counterparts.

The Chevrolet, Chevelle
and
Camaro integral gear type

power steering
has the
hydraulic pressure delivered

from
the
pump through two hoses
to the
steering gear.
In
the power steering gear
the
steering shaft, hydraulic

valve, worm, and rack-piston
nut are all in
line making
a

compact
and
space saving assembly.
All oil
passages
are

internal within
the
gear except
the
pressure
and
return

hoses.

The steering gear
is a
recirculating ball system
in

which steel balls
act as a
rolling thread between
the

steering worm
and
rack-piston
nut. The
rack-piston
nut

is
all one
piece
and is
geared
to the
sector
of
the piston

shaft.
The
valve
is
contained
in the
gear housing elimi-

nating
the
need
of
bolts
or
seals
to
attach
a
separate

valve housing.

The valve
is an
open-center, rotary-type three
way

valve.
The
spool
is
held
in
neutral position by means
of a

torsion
bar. The
spool
is
attached
by
means
of
the stub

shaft
to one end of the
torsion
bar
and
to the
valve body

on
the
other
end.
Twisting
of the
torsion bar allows
the

spool
to
move
in
relation
to the
valve body thereby oper-

ating
the
valve.

MAINTENANCE
AND
ADJUSTMENTS

BLEEDING HYDRAULIC SYSTEM

1.
Fill
oil
reservoir
to
proper level and
let oil
remain

undistrubed
for at
least two minutes.

2.
Start engine
and run
only
for
about
two
seconds.

3.
Add
oil if
necessary.

4.
Repeat above procedure until
oil
level remains
con-

stant after running engine.

5. Raise front
end of
vehicle
so
that wheels
are off
the

ground.

6. Increase engine speed
to
approximately
1500 rpm.

7. Turn
the
wheels
(off
ground) right
and
left, lightly

contacting
the
wheel stops.

8. Add
oil if
necessary.

9. Lower
the car and
turn wheels right and left
on the

ground.

10.
Check
oil
level and refill
as
required.

11.
If oil is
extremely foamy, allow vehicle
to
stand
a

few minutes with engine
off and
repeat above

procedure.
,

a.
Check belt tightness
and
check
for a
bent
or
loose

pulley. (Pulley should
not
wobble with engine

running.)
b.
Check

proper level
if
neces-

sary, following operations
1
through
10.
This

step
and
Step
"D" are
extremely important
as

low
oil
level and/or
air in the oil are the
most

frequent causes
of
objectionable pump noise.

d. Check
the
presence
of air in the oil. If air is

present, attempt
to
bleed system
as
described
in

operations
1
