Check that the hose does not touch other parts at
any time during suspension or geometry travel.
If contact does occur, remove the U-shaped retainer
and rotate the end of the hose in the support bracket
one or two points in a direction which will eliminate
hose contact. Reinstall the retainer and recheck
for hose contact. If it is satisfactory, place the
steel tube connector in the hose fitting and tighten
securely.
If rear brake caliper is being serviced, connect
brake line to caliper.
Bleed brakes as outlined in this section.
Install wheels and lower vehicle.
BRAKE DISC
Servicing of the disc brakes is extremely critical
due to tolerances required in machining of the brake
disc to insure proper brake operation. In manufacturing
the brake disc, tolerances of the rubbing surfaces for
flatness is .001 and for parallelism is .0005, while
lateral runout of the faces must not exceed .004 total.
The maintenance of these close controls of the shape of
the rubbing surfaces is necessary to prevent brake
roughness. In addition, the surface finish must be non-
directional and maintained at 30-50 micro-inches. This
control of the rubbing surface finish is necessary to
avoid pulls and erratic performance and promote long
lining life and equal lining wear of both left and right
brakes.
tight scoring of the disc surfaces not exceeding .015
in depth, which may result from normal use, is not
detrimental to brake operation.
When the total disc thickness is less than .965 for the
1"
thick disc or 1.215 for the 1-1/4" thick disc, it should
be replaced. Disc thicknesses less than this can permit
the shoes to come out of contact with the shoe abutments
and cause malfunction.
Because performance is not impaired by surface im-
perfection not exceeding .015 deep, refinishing of the
rubbing surface is not necessary.
Fig.
43—Dial Indicating Disc Runout
Since extremely accurate control of the finishing oper-
ation is necessary for proper performance and excess
metal removal can cause malfunction, refinishing of the
rubbing surface is not recommended.
Checking Procedure (Fig. 43)
Front
Tighten the adjusting nut of the wheel bearing until all
play has been removed. It should be just loose enough
to allow the wheel to turn. Clamp a dial indicator to the
caliper so that its button contacts the disc at a point about
1 inch from the outer edge. When the disc is turned, the
indicator reading should not exceed .002 inches. If runout
exceeds this amount the hub and disc assembly should
be replaced. Due to the close tolerances involved it is
not recommended that the front discs be machined or
serviced separately.
After checking the runout, readjust, the wheel bearings
as outlined in Section 3 of this manual.
Rear—Corvette Only
Check the rear wheel bearing end play, as outlined in
Section 4 of this manual. Then dial indicate the disc face.
If lateral runout of the disc exceeds the bearing end play
by .003 inches, the disc should be refaced (not to exceed
.040 inches) or replaced.
Removal
1.
Raise vehicle and remove wheel and tire assembly.
/ 2. Remove brake caliper as outlined in this section.
3.
Drill out the five rivets attaching the disc to the hub
or spindle.
4.
Remove brake disc from vehicle.
5. Complete the removal of the five rivets from the
hub or spindle.
Installation
1.
Install the disc to the hub or spindle aligning the lug
bolts with the holes in the disc.
CHEVROLET CHASSIS SERVICE MANUAL

CLUTCH AND TRANSMISSIONS 7-10 ,
GENERAL DESCRIPTION
The overdrive unit is essentially a two-speed planetary-
transmission attached to the rear of a conventional three-
speed transmission. In overdrive, engine speed is ap-
proximately 30 per cent slower at a given road speed
since the drive train includes planetary gears which pro-
vide a lower overall gear ratio than that obtained in high
gear with the conventional transmission.
The electrical equipment which controls the automatic
action of the mechanical portion of the overdrive unit
consists of a solenoid, a speed-sensitive governor switch,
a relay and a kickdown switch. The circuit including this
equipment makes it possible to operate in overdrive above
a pre-set cut-in speed, or in .conventional drive at any
speed.
With the overdrive unit engaged, the transmission
should not be left in any forward gear with intent of lock-
ing the drive-line as the overrunning clutch is a free-
wheeling condition.
SERVICING THE OVERDRIVE
With the,overdrive assembly removed from the trans-
mission, service operations on the transmission proper
are the same as for the standard three-speed trans-
mission.
Repairs to the overdrive housing, output shaft, ring
gear assembly, clutch cam, roller retainer, pinion cage,
sun gear, shift rail, sun gear control plate, output shaft
bearing, oil seal, speedometer drive gear, solenoid pawl
and interlock plunger may be performed underneath the
car, if so desired, by removing the overdrive housing
without disturbing the transmission. Refer to Overhaul
Manual for Service Procedure.
If the transmission mainshaft, overdrive adapter or
transmission rear bearing which is retained in adapter
require replacement, the entire transmission and over-
drive assembly should be removed and overhauled on the
bench.
MAINTENANCE AND ADJUSTMENTS
Servicing of the overdrive governor switch and pinion,
the sun gear solenoid, oil seal and cable bracket, the out-
put shaft rear oil seal, the control shaft lever, and the
speedometer driven gear may be accomplished without
removing the overdrive from the vehicle, as discussed
in the following paragraphs:
GOVERNOR SWITCH AND PINION
To remove governor switch, disconnect wires at gover-
nor switch and screw governor
out
of housing, using Tool
J-4653 on the flat hexagonal surface of governor case.
The pinion may be separated from the governor by re-
moving the snap ring on the shaft.
SUN GEAR SOLENOID, OIL SEAL AND
CONTROL CABLE BRACKET
Remove the solenoid by taking out the two mounting
bolts and lock washers, removing
the.
cable bracket with
the lower bolt. Turn the solenoid 1/4 turn and
pull,
sole-
noid plunger out of adapter. The oil seal may be pried
out of the adapter.

DIAGNOSIS-OVERDRIVE
MECHANICAL
Any one of the following general complaints may be due
to non-standard mechanical conditions in the overdrive
unit:
1.
Does not drive unless locked up manually.
2.
Does not engage, or lock-up does not release.
3.
Engages with a severe jolt, or noise.
4.
Free-wheels at speeds over 30 mph.
These^ troubles may be diagnosed and remedied as de-
scribed in the following paragraphs.
1.
Does not drive unless locked up manually.
a. Occasionally, the unit may not drive the car for-
ward in direct drive, unless locked up by pulling
the dash control. This may be caused by one or
more broken rollers in the roller clutch, the
remedy for which is the replacement of the entire
set of rollers.
b.
This may also be caused by sticking of the roller
retainer upon the cam. This retainer must move
freely to push the rollers into engaging position,
under the pressure of the two actuating springs.
c. Sometimes this is due to slight indentations, worn
in the cam faces by the rollers spinning, remedied
by replacement of the cam.
2.
Does not engage, or lock-up does not release
.. a. Dash control improperly connected—-Unless the
overdrive dash control wire is connected to the
lockup lever on the left side of the overdrive
housing in such a manner as to move the lever
all the way back when the dash control knob is
pushed in, it may hold the shift rail in such a po-
sition as to interlock the pawl against full engage-
ment resulting in a buzzing noise when overdrive
engagement is attempted.
To correctly make this connection, loosen bind-
ing post at lever, pull dash control knob out 1/4",
move lever all the way to the rear, and tighten
binding post.
b.
Transmission and overdrive improperly aligned—
The same symptoms as above may also result
from misalignment, at assembly, of the overdrive
housing to the transmission case, resulting in
binding of the overdrive shift rail, so that the re-
tractor spring cannot move the rail fully forward,
when the dash control knob is pushed in, and the
transmission is not in reverse. Under such con-
ditions, the unit may remain fully locked up.
To test for this, be sure that the transmission
is not in reverse; disconnect the dash control
wire from the lockup lever, and feel the lever for
free forward movement. If the lever can be
moved forward more than 1/4", it indicates that
misalignment probably exists. To correct this,
Jposen the capscrews between the overdrive hous-
ing and transmission case, and tap the adpater
plate and overdrive housing until a position is
found where the rail shifts freely; tighten cap-
screws.
c. Kickdown switch improperly adjusted—The posi-
tion of the kickdown switch should be adjusted,
by means of the two large nuts which clamp the
switch shank, so the switch plunger travels 3/16"
before the throttle lever touches its stop.
Occasionally the large nuts which clamp the
switch through the switch bracket are tightened
sufficiently to bend the switch shank, thus pre-
venting free motion of the switch stem. This may
usually be remedied by loosening the upper of the
two nuts.
d. Improper installation of solenoid—If car cannot
be rolled backward under any circumstances and
there is no relay click when the ignition is turned
on, it probably indicates that the solenoid has
been installed directly, without twisting into the
bayonet lock between solenoid stem and pawl, thus
jamming the pawl permanently into overdrive en-
gagement. If the car will occasionally roll back-
wards, but not always, (and there is no relay click
when the ignition switch is turned on) it may indi-
cate that, upon installation, the bayonet lock was
caught, and the solenoid forcibly twisted into
alignment with the attaching flange, thus shearing
off the internal keying of the solenoid. Under
these circumstances, the end of the solenoid stem
may not catch in the pawl, and upon release of the
solenoid, the pawl will not be withdrawn promptly
from engagement, but simply drift out. If the
solenoid stem end has its two flats exactly facing
the two solenoid flange holes, it will not withdraw
the pawl properly. If the stem can be rotated
when grasped by a pair of pliers, it indicates that
the internal keying has been sheared.
e. Improper positioning of blocker ring—Occasion-
ally, either in assembly at the factory, or in
service operations in the field, the internal parts
of the overdrive unit may have been rotated with
the solenoid pawl removed, causing the blocker
ring to rotate, so that its two lugs are not located
with respect to- the pawl as shown in Figure 12B.
In other words, the solid portion of the blocker
ring may be in alignment with the pawl, which will
prevent fill} engagement of the pawl with the sun
gear control plate/
To test for this condition, remove solenoid
cover, pull dash control knob out, roll car 2 ft.
forward. Push dash control in, turn ignition
switch on. Then ground the "KD" terminal of
relay, and watch movement of center stem of
solenoid. It should not move more than 1/8" when
the solenoid clicks. Then, with the relay terminal
still grounded, shift into low gear, and roll car
forward by hand. Solenoid stem should then move
an additional 3/8", as the pawl engages fully.
These two tests indicate proper blocker action.
Unless both tests are met, the blocker ring is
probably not in the correct position.
3.
Engages with a severe jolt or noise
Insufficient blocker ring friction may cause the ring
to lose its grip on the hub of the sun gear control
plate. Check the fit and tension of the ring as de-
scribed under "Cleaning and Inspection".
4.
Free-wheels at speeds over 30 MPH
If cam roller retainer spring tension is weak the unit
will free wheel at all times. Check spring action as
described under "Cleaning and Inspection".
