ELECTRICAL

Any one of the following general complaints may be due

to electrical trouble in the overdrive circuit.

1.
Does not engage.

2.
Does not release.

3.
Does not kickdown from overdrive.

These troubles may be traced and remedied as de-

scribed in the following paragraphs.

1.
Does not engage

a. With the ignition switch on, ground the "KD" ter-

minal of the solenoid relay with a jumper lead.

If the solenoid clicks, the relay and solenoid cir-

cuits are in operating condition. If no click is

heard in the relay, check the fuse and replace if

defective.

b.
If the fuse is good, use a second jumper lead to

connect the "SOL" and "BAT" terminals of the

relay. If a click is now heard in the solenoid, the

relay is probably at fault and should be repaired

or replaced.

c. If the solenoid does not click in Step b, check the

wiring to the No. 4 terminal of the solenoid and

replace if necessary. If the wiring is not defec-

tive,
the trouble is probably in the solenoid. Re-

move the solenoid cover, examine the solenoid

contacts in series with the pull-in winding and

clean if necessary. Test again for clicks, as in

Step b, after replacing solenoid cover and lead

wires.
Replace the solenoid if trouble has not

been corrected.

d. If the relay and solenoid circuits are in good con-

dition as determined in Step a, leave the ignition

switch on and make sure the manual control knob

is in the overdrive position. Ground one and then

the other of the two terminals next to the stem of

the kickdown switch (identified as "SW" and
?fREL"). K the solenoid clicks when one terminal

is grounded but not the other, replace the switch.

If the solenoid does not click when either of the

terminals is grounded, check the wiring between

the relay and the kickdown switch and replace if

defective.

e. If the solenoid clicks as each terminal is grounded

in Step d, ground the governor switch terminal.

If the solenoid clicks, the governor switch may be

defective. If the solenoid does not click, check

the wiring between the kickdown and governor

switches and replace if necessary.

2.
Does not release

a. Remove the connection to the "KD" terminal of

the relay. If this release overdrive, look for a

grounded control circuit between the relay and

governor switch.

b.
If the overdrive is not released in Step a, dis-

connect the lead to the "SOL" terminal of relay.

If this releases the overdrive, replace the relay.

3.
Does not kickdown from overdrive

a. With the engine running, connect a jumper lead

between the No. 6 terminal of the solenoid and

ground. Operate the kickdown switch by hand.

This should stop the engine. If it does, the sole-

noid is probably defective and it should be checked

for dirty ground-out contacts or other defects

within the ground-out circuit of the solenoid (fig.

4B).
Clean the contacts or replace the contact

plate as required.

b.
If the engine does not stop in Step a, ground one

and then the other of the two terminals (Identified

as "IGN" and "SOL") farthest from the sfem of

the kickdown switch. The engine should stop when

one of the two terminals (IGN) is grounded. If

the engine does not stop when the terminal is

grounded, the wiring or connections to the switch

between the switch and coil are defective. When

the btlier terminal (SOL) is grounded, the engine

should stop when the kickdown switch is operated.

If the engine does not stop when the kickdown

switch is operated with the second terminal

grounded, the kickdown switch is defective. If

the trouble is in the kickdown switch, adjust the

linkage to give more travel of the switch rod.

If this does not correct the trouble, replace the

kickdown switch.

If the kickdown switch operates as it should,

check for an open circuit in the wiring between

the kickdown switch and the No. 6 terminal of the

solenoid.

c. If the trouble is not located by the above checks,

the upper contacts of the kickdown switch may not

be opening. To check for this condition, ground

the overdrive control circuit at the governor

switch. This should cause the solenoid to click.

Operate the kickdown switch by hand. This should

cause a second click as the solenoid releases.

If there is no second click, adjust the linkage to

give more travel of the switch rod. If this does

not correct the trouble, replace the kickdown

switch.

GENERAL DESCRIPTION

The Borg-Warner heavy duty three speed fully syn-

chronized (all forward gears) transmission incorporates

helical gears throughout specially designed to provide

high torque capacity, and gear teeth proportion to operate

at high speeds with neither excessive heat generation nor

excessive frictional losses. Shafts, bearings, high ca-

pacity clutches and other precision parts are held to

close limits providing proper clearances necessary for

durability during extended heavy usage.

The main drive gear is supported by a heavy duty 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 heavy duty ball bearing mounted in the

front of the extension housing.

The countergear is carried on a double 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. An 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 reverse idler gear is carried on 25

roller bearings while thrust is taken on thrust washers

located between the ends of the gear and the thrust bosses

of the case.

Gear shifting is manual through shift control rods from

the shifter tube in the mast jacket to the rearward shift

lever of the side cover assembly for first and reverse

gear; and through a cross shaft assembly attached to the

forward side cover lever for second and third gear. All

three forward gears are fully synchronized. The syn-

chronizer 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. The transmission may be used as an aid

in deceleration by downshifting in sequence without

double-clutching or any gear clashing. Reverse is not

synchronized, however, it is a helical gear to insure

quiet operation.

GENERAL DESCRIPTION

The four-speed synchromesh transmission incorpo-

rates helical gears throughout specially designed to pro-

vide high torque capacity without additional weight, and

gear teeth proportioned to operate at high speeds with

neither excessive heat generation nor excessive fric-

tional losses. Shafts, bearings, high capacity clutches

and other precision parts are held to close limits, pro-

viding proper clearances necessary for durability during

extended heavy usage.

The main drive gear is supported by a heavy-duty 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 heavy-duty ball bearing mounted at the

rear end of the transmission case in a retainer casing.

The counter gear is carried on a double 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.

The two-piece reverse idler gear is carried on bronze

bushings while thrust is taken on thrust washers located

between the front of the gear and the back of the reverse

idler thrust boss and between the rear of the gear and the

reverse idler shaft boss in the case extension.

Gearshifting is manual through shift control rods to the

transmission cover shifter levers for first through fourth

gears,
and to the reverse lever located in the case ex-

tension. The shifter lever to the rear of the transmis-

sion cover controls first and second gears while the

lever to the front controls third and fourth gears. All

four forward gears are fully synchronized. The trans-

mission may be used as an aid in deceleration by down-

shifting in sequence without double clutching. Reverse is

not synchronized, however, it is a helical gear to insure

quiet operation.

Replacement

In the event replacement is necessary use the following

procedure.

1.
Remove seat separator (console) assembly.

2.
Remove shift lever seal retainer and slide seal up

on lever.

3.
Remove shift lever knob, and the 2 lever to bracket

retaining nuts and remove the lever assembly.

4.
Replace blocker cable - thread new cable up through

lever and MT" handle and install cable retainer

through access slot. Adjust retainer to hold blocker

end .010/.020" above lever bracket surface, then lock

and cut off excess cable.

5.
Reverse Steps 1, 2 and 3 to install.
Figure 3M shows the adjustment and lubrication proce-

dure for the mechanism. This Figure applies to both

models of lever assemblies.

NOTE: If, for any reason, the cable assembly

is removed from the handle, it is difficult to in-

stall without rework. This is due to the fact that

the extra length of the cable is trimmed after

assembly and, therefore, it is almost impossible

to get the shortened cable to enter the cable hole

in the cylindrical retainer.

If new service cable assemblies are not available, the

original part can be re-used by butt soldering a 2.00 inch

piece of small wire to the cable end. Trim the solder

joint so that it will pass through the hole in the retainer.

After assembly, trim off the excess wire as shown in

Figure 3M.

Adjustment

1.
With set screw loose, assemble cable through hole

in cylindrical retainer above handle.

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.
