to previous heat. The vehicle should be returned to the

Dealership the next day (at least 12 hours) to give clutch

time to cool to normal temperatures. Any slippage

should then be evaluated as follows:

1.
Drive in high gear at 20-25 MPH.

2.
Depress clutch pedal to the floor and rev engine to

2500-3500 rpm.

3.
Engage clutch quickly (snap foot off pedal) and press

accelerator to full throttle.

Engine speed should drop noticeably then accelerate

with vehicle. If clutch is bad, the engine speed will in-

crease.

GENERAL DESCRIPTION

The Saginaw four speed fully synchronized
(all
forward

gears) transmission incorporates helical drive gears

throughout.

The main drive gear
is
supported
by a
ball bearing
at

the front
end of the
transmission case and
is
piloted
at its

front
end in an oil
impregnated bushing mounted
in the

engine crankshaft.
The
front
end of the
mainshaft
is

piloted
in a row of
roller bearings
set
into
the
hollow
end

of
the
main drive gear
and the
rear end
is
carried
by a

ball bearing mounted
in the
front
of the
extension housing.

The countergear
is
carried
on a
single
row of
rollers

at both ends while thrust
is
taken on thrust washers
lo-

cated between
the
ends
of the
gear and
the
thrust bosses

in
the
case. Ah anti-rattle plate assembly
at the
front
of

the countergear provides
a
constant spring tension
be-

tween
the
counter
and
clutch gears
to
reduce torsional

vibrations.
The
sliding reverse idler gear
is
carried
on

a bushing finish bored
in
place.
It
rotates
on a
short

idler shaft retained by
a
woodruff
key.

The synchronizer assemblies consist
of a
clutch
hub,

clutch sleeve,
two
clutch
key
springs and three energizer

clutch keys
and are
retained
as an
assembly on
the
main

shaft
by a
snap ring.
A great deal
of
similarity
and
interchangeability
now

exists between
the new 3 and
4-speed Saginaw trans-

missions.

However,
the
synchronizer assembly
at the
front
of the

mainshaft
is
used
for the
third and fourth rather than
the

second
and
third shift.
The
synchronizer assembly
at

the rear
of the
mainshaft
is
used
for the
first and second

rather than
the
first
and
reverse shift. Gear teeth
cut

in
the
first and second synchronizer sleeve (reverse gear)

distinguish
it
from
the
third
and
fourth synchronizer

sleeve.

Starting from
the
front, gears
on the
mainshaft
are

third, second
and
first rather than second, first and
re-

verse.
A
fourth blocker ring
is
used between
the 1-2

synchronizer assembly
and
first gear
on the
four-speed

transmissions.

The cover
on the new
four-speed transmission
is lo-*

cated
on the
left-hand side
of the
case.
It is
similar
to

the three-speed cover with
the
addition
of a
reverse

shifter shaft assembly, detent ball
and
detent spring.

Disassembly
and
assembly procedures
are
covered
in

this section.

Fig.
26—Gasoline Tank (36 Gallon) Compartment Cover

from the fuel tank pickup at the bottom of the tank, along

the rear frame crossmember to the right frame rail,

extending through the rail at the kickup area and along the

top inside edge of the frame to the fuel pump, Flexible

hoses are located at the fuel tank pickup and at the fuel

pump.

36 Gallon Tank

The 36 gallon tank fuel lines are routed from the bot-

tom of both sides of the tank to the right frame rail

(fig. 20).

Maintenance

CAUTION: Always drain gasoline from the

complete fuel system including carburetor, fuel

pump and all fuel lines and fuel tank if the vehi-

cle is to be stored for any great length of time.

This precaution will prevent accumulation~ol

gum formation and resultant poor engine

performance.

. The fuel lines should occasionally be inspected for

leaks,
kinks or dents, especially when work has been

done on the underside of car or after the car has been

traveling over rough or stone roads at higher speeds.

If evidence of dirt is found in the carburetor or fuel pump

at disassembly, the lines should be disconnected and

blown put. Check the fuel tank strainer for damage or

omission.

Fuel lines are beaded-type ends for connection to

hoses and flared ends for secure metal-to-metal line

connections.
