Between these two adjustment areas the angle and level for the front
fender is quite widely adjustable, don't forget to loosen the inner
fender to firewall three bolts!!! I believe the shop manual shows all
this, but of course the body man probably doesn't have one. Take him

Brake Information - General From the Shop Manual
The primary shoe is the shorter one and goes on the forward side. The
secondary shoe is the longer and goes on the rearward side.
The anchor
block must be mounted correctly. There are two means of checking the installation; the curved side must contact the
primary shoe and the arrow must point toward the primary shoe.
Adjusting Brakes by Ross Hiller ( from the Florida Packard Club newsletter, The Packard Courier October 2004.)
This
tip
is
for cars with hydraulic brakes only. When adjusting brakes, loosen the
handbrake adjustment at the equalizer
(at the center of the "X" in the frame) until the cables are quite
slack. In fact, push, them into their sheathes as far as you can. This
insures that the rear brake shoes are not being held apart by the
parking brake mechanism. Now, adjust the rear brakes using the star
wheel. I recommend tightening the star wheel (pull up on the end of
your adjusting tool) until the wheel can no longer be turned. This
settles the shoes firmly against their anchors. Then, back the star
wheels off about 10 clicks or so till there is no appreciable drag on
the drum.
After adjusting both
rear wheels, readjust the hand. brake mechanism:
Adjusting
the
brakes
in this way will let the rear shoes have full
contact. with the drum. and will let them have the self-energizing
"servo" action they were designed for. This will result in lighter
pedal pressure, less brake fade. and longer lining life. Most
complaints about "push and pray" brakes can be solved in this way.
If your car has one of
those little cable shortening gizmos on the
handbrake cable, I can guarantee the brakes are not adjusted properly.
I have not yet seen a case where the cables were stretched and needed
such a thing. I have however put about a dozen of them in the trash
after adjusting the brakes properly.
Silicone Brake Fluid & Stoplight Switch Fix By Bill Cathcart
When I restored my 1960 Lark in 1985, I put silicone fluid in the brake
system. To date, I have had no problem except for a brake
light switch failure. My switch failed about twice a year.
It would require more and more pressure to light the stoplights until
they would not work at all. If you use silicone fluid in your
Studebaker, you know that this is an ongoing problem.
How do you solve this problem? I solved it by changing over to a
mechanical switch-an easy conversion if your pedals come up through the
floor. Go to your local NAPA store and buy an Echlin SL-128 switch. This
is a spring loaded switch that will follow the brake pedal as it goes
down lighting the lights.
To install the switch, remove the pedal cover under the left front
fender, locate the switch in a position so it will follow the
brake pedal down without the switch lever coming off the brake arm, mark
the two holes and drill through the floorboard (remember to remove the
mat).
I believe the switch takes 8-32 screws. Have someone hold the switch in
position and install the two screws from inside, extend the wires to the
new switch, now replace the rubber pedal stop between the pedal and the
floor with a slightly thicker piece, and readjust the master cylinder
rod about a 11/16th of an inch shorter. Test for proper operation and
reinstall the pedal cover and your brake light problems are over.

COOLING
Cooling System Tip By Randy Rundle (From The Alternator Gazette - Fifth Avenue Garage)
There are two things you can do to benefit most any vintage cooling
system. The first is to run straight distilled water in the cooling
system during the summer months, with no antifreeze, and a pind of rust
inhibitor/water pump lubricant. Water is the best dispersant of heat
there is. This simple trick is good for a twenty degree drop in engine
temperature.
Next up, pressurize your cooling system and add an overflow
coolant tank. Five pounds is enough. The five pounds of pressure will
raise the boiling point of your engine cooland to 227 degrees. The
pressure will also create enough vacuum in the cooling system to draw
the overflow coolant back into the radiator as the engine cools.
Checking Your Antifreeze by
Jerry Kurtz (From Keystone Region Chapter-Keystone Keynotes April
2001)
If you're like most of us, we open the radiator cap, look
to see if
the fluid is green, the right number of balls float in our tester, and
there isn't too much brown stuff floating around. We then consider the
radiator serviced and put the cap back on.
Permanent antifreeze is permanent in name only. In reality antifreeze
needs to be changed periodically like we change other fluids in our
car.
Antifreeze has a life of approximately 3 years, however the inhibitors
don't last that long so it really is a good idea to change it annually.
An accurate test to determine the viability of your
antifreeze is to
attach the positive lead from a digital volt-ohm meter to the metal
part
of the radiator, then center the negative lead into the coolant itself.
A voltage reading of 0.2 or less is very good. A reading of 0.5 should
be considered borderline, while anything over 0.7 is unacceptable.
If your coolant fails this test the coolant system should
be drained
and flushed and fresh antifreeze should be added.
There is a new generation of "lifetime" antifreezes being
promoted.
Do not mix these with the ethylene glycol antifreeze that has been in
use
for the last sixty years, as they are not compatible. I do not
recommend
using lifetime antifreeze in collector cars. I understand that it will
seep everywhere, including into the cylinder areas, in cars not
assembled
with the newer rubber bonded steel gaskets.

ELECTRIC
Good System Ground: By Randy Rundle (From The Alternator Gazette - Fifth Avenue Garage)
One of the
easiest improvements you can make to your vehicle's electrical system
is to improve the system ground. To do this you need to move the battery
ground cable so it goes directly from the negative post of the battery
(negative ground system) to a starter mounting bolt. It was common
practice (even from the factory) to connect the battery ground cable to
either the motor or the frame. By doing this, part of you battery
cranking power is lost trying to overcome the resistance along this
indirect path. High resistance in the starting circuit results in a slow
cranking engine, or one the doesn't start at all when it's hot.
Erratic charging: by
Fred Birdsell (From Western Lake Erie Chapter-The Driver's Seat)
On 12-volt generator systems, the voltage regulators are
very
troublesome. Erratic charging is the least of the problem. In the worst
case, points will stick, fusing the wiring into a very hot glow plug.
We
have had this happen with two of our Hawks. It's no fun replacing the
wiring
harness.
Alternator cars are NOT immune. If a diode fails, a dead
short
can also occur. Because this happens VERY quickly, even a battery
cut-off
switch will not prevent major damage. The best solution I am aware of,
is to install a circuit breaker on the battery terminal of the voltage
regulator. Ask NAPA for an Ecklin circuit breaker #CB 6379 (50 amp).
The
breaker will have two posts. Bolt one to the BATTERY post of the
regulator,
the other to the wire to that post.
A second solution (less likely to cause a point deduction
during
show judging) is to install a fusible link in the wire connecting the
starter
solenoid to the ammeter (see your shop manual). The fusible link wire
needs
to be 4 gauges smaller than the ammeter wire.
Take the wire off the "BAT" terminal of the regulator and
attach
it to the "AUX" terminal of the circuit breaker. Then make a new wire
(of
adequate gage, of course) to go between the "BAT" terminal of the
circuit
breaker and the "BAT" terminal of the regulator.
Headlight
Switch Fix - By Gary Capwell (From 56J Only
September 25, 1995)
Here is a solution to the problem; the headlight switch doesn't
work....the cause being that the hard cardboard isolator plate is
warped far enough to prevent the contacts from touching the back of the
switch. I removed this isolator plate and traced its outline on an old
plastic playing card, then used a paper hole punch to make the contact
holes. The result is amazing...like a new switch, but a whole lot
cheaper and easier to get. To do this you need to bend the tangs up to
remove the back, and do not turn the housing upside down (leave the
back facing up). The isolator plate is directly under the back of
switch. This is how I spent yesterday evening, as the lights would not
work but the dash lights did. The longest time was spent pinpointing
the switch as the source of the problem, the solution was simple enough
that I plan on doing the same repair to the dash light switch in the
near future, as it works, but requires a little jiggling to
Horn
Wire
&
Power
Steering by
Gary Capwell (From 56J Only)
Repairing the horn wire in your power steering equipped 56J can be a
real exercise in futility!...But here are a few things that are not in
the Studebaker shop manual that you should take note of before
attempting a repair.
1.) Remove your Ultramatic's shift selector indicator, it'll get broken
if you don't!
2.) Remove your front seat bottom cushion after removing the steering
wheel, grease stains are hard to get out!
3.) Plan on removing the entire steering shaft and column!
4.) Try to have a helper handy, especially when reassembling - to keep
the column straight.
5.) Don't forget to reinstall the column to dash shims.
The most important aspect of this repair is to ensure that the column
is straight, any angle causes the horn to short when the wheel is
rotated, even if the wire is fine! Also, before tightening the clamp on
the column cover (at gearbox) be sure that the brass brush contact is
in the center of the hole! You can remove the steering shaft from the
column cover without any trouble, but remember to set the cover down
with the duffy plate hanging off the end of a table to keep from
damaging it! These are things I learned the first, frustrating, time I
tried to repair my horn wire! After learning these things, the second
try (six months later) went quite smoothly and actually accomplished
the repair! And no all those wires aren't the biggest hassle.

Electric Fuel Pump: By Randy Rundle (From The Alternator Gazette - Fifth Avenue Garage)
Adding an
electric fuel pump has almost become a necessity. The new RFG fuel
evaporates very rapidly, especially in the summertime. You need a fuel
pump that will pump alcohol, all fuel additives, and the RFG gasoline
without failure. Also impoirant is to find a fuel pump that maintains
the original fuel pump pressure, while increasing the volume of fuel
delivered. Too much fuel pump pressure against the needle and seat in
the carburetor will result in the carburetor flooding over. A gear
driven fuel pump works much like the oil pump inside of the engine and
maintains the stock fuel pump pressure while increasing the volume of
fuel delivered. Geardriven electric fuel pumps are quiet, and a great
way to overcome vapor lock, and increase the reliability of your fuel system.

WHEELS AND TIRES What to put on
Our 1956 Golden Hawks came standard with
15"X5" wheels and 7:10-15 tires. The
closest equivalent radial tires are P205/75R15, P215/75R15 and
P225/75R15. The
following table shows various specifications which I took from the Coker
Tire
Catalog:
TIRE |
DIAMETER |
RIM WIDTH |
710-15 |
27.75" |
5" |
P205/75R15 |
27.11" |
5" - 7.5" |
P215/75R15 |
27.62" |
5.5" - 7.5" |
P225/75R15 |
28.98" |
6" - 8" |
Diameter is the distance from the ground to the top of the tire. Rim Width is the size of the wheel itself (2nd # of the wheel size as 15X5)
Coker Tire indicates that the P215/75R15 size is the best match to the 710-15 tire. This presents a problem because the width of the wheel on our cars is 5". The recommended minimum wheel width for the P215/75R tire is 5.5". This leaves a couple of options.• You can keep your original wheels and use a P205/75R15 tire.
• You can buy new wider wheels and use the P215/75R15 or P225/75R15 tire.
Many people have used wheels from full size Chrysler products. However, buying from a junk yard is a gamble. Unless you can arrange to have each wheel checked before you mount the tire, and return any that are bent or out of round, you are simply compounding the problem.Bob Palma states that you can buy Nationl Wheel & Rim Association (NWRA) #40273, or Hayes #82552 wheels which will allow use of a P205 or P215 radial tire.
Option 3 is to simply put new 710-15 tires on your original wheels. They are still available from Coker tire and the cost is less than wide whitewall radial tires.INSTRUMENTS
Tachometer Troubles:
By Geoff Fors (56J ONLY issue 010)
A member wrote that his tach would fall to zero above 1000 rpm
and sometimes stay there for the rest of the time the engine was
running.
I had the same problem and discovered that the tach head, unlike most
tachs,
is not just a big meter but actually has a motor inside it which
requires
cleaning and lubrication of its bearings just like any other motor. The
tach head motor apparently operates like a synchro motor as found in
aircraft,
and if the tach motor bearings are somewhat dry it isn't able to spin
as
easily above engine rpm of 1000 or so and it then lags behind the
distributor
signal enough to finally fall to zero. The tach motor is designed to
stay
in step with the distributor rotor and anything that interferes with
this
relationship will cause the tach motor to stop turning. If the idle of
the engine is low enough, the tach needle may start working again when
the engine is brought back to idle because the pulse lengths from the
distributor
sender are longer and provide the voltage necessary to get the tach
motor
started again from a dead stop. I am trying to find a suitable oil to
use
in the tach bearings. Some sort of clock oil or delicate instrument oil
would probably be correct. For goodness' sake, I hope everyone knows by
now not to use WD-40 in clocks or instruments ! A good shop which
advertises
tach repair in Hemmings may be able to help. If they aren't familiar
with
S-W "Pulsemotor Drive" tachs, though, look elsewhere.
