REMOVAL AND INSTALLATION

REMOVAL

1.
To maintain drive line balance,

mark the relationship of the rear drive

shaft yoke and the drive pinion flange

of the axle (if the yellow alignment

marks are not visible) with the shaft

so that they may be installed in their

original positions.

2.
Disconnect the rear U-joint or

rear double cardan joint from the

companion flange. Wrap tape around

the loose bearing caps to prevent

them from falling off the spider. Pull

the drive shaft toward the rear of the

vehicle until the slip yoke clears the

transmission extension housing and

the seal. On Lincoln Continental

models, remove the three roller bear-

ing assemblies off the spline teeth in-

side the slip yoke (Fig. 3). Install the

appropriate tool in the extension

housing to prevent lubricant leakage.

INSTALLATION

1.
If either the rubber seal on the

output shaft or the seal in the end of

the transmission extension housing is
damaged in any manner, replace the

seal or seals as required. Also, if the

lugs on the axle pinion flange are

shaved or distorted so that the bear-

ings slide, replace the flange.

2.
On Lincoln Continental models,

install the bearing assemblies over the

spline teeth in the slip yoke. Lubricate

the yoke spline with B8A-19589-A lu-

bricant. This spline is sealed so that

the transmission fluid does not

"wash" away the spline lubricant

(Figs.
4 and 5). Remove the tool from
the extension housing. Install the yoke

on the transmission output shaft. Do

not allow the yoke assembly to bot-

tom on the output shaft with excessive

force.

Install the drive shaft so that the

index marks or the yellow mark (if

visible) on the yoke (light side) is in

line with the yellow mark on the com-

panion flange. This prevents vibration

which occurs when the balance of the

shaft and balance of the axle pinion

flange become additive instead of neu-

MAJOR REPAIR OPERATIONS

Before removing
any of the sub-

assemblies, thoroughly clean
the out-

side
of the
transmission
to
prevent dirt

from entering
the
mechanical parts.

During
the
repair operations, refer
to

Part 7-1
for
common adjustments
and

repairs
or
cleaning
and
inspection
pro-

cedures.

During
the
transmission disassem-

bly
or
assembly operations,
ten
thrust

washers located between
the sub-

assemblies must
be
removed
and in-

stalled.
It is
important that each

thrust washer
be in the
correct posi-

tion during
the
assembly operation.

To properly locate
and
identify
the

thrust washers,
the
various positions

of
the
thrust washers
are
shown
in the

illustrations
and are
numbered
1

through
10. No. 1 is at the
first thrust

washer located

REPLACEMENT

During the repair of the sub-

assemblies, certain general instructions

which apply to all units of the trans-

missions must be followed. These in-

structions are given here to avoid un-

necessary repetition.

Handle all transmission parts care-

fully to avoid nicking or burring the

bearing or mating surfaces.

Lubricate all internal parts of the

transmission before assembly with

clean automatic transmission fluid. Do

not use any other lubricants except on

gaskets and thrust washers which may

be coated with vaseline to facilitate

assembly. Always install new gaskets

when assembling the transmission.

Tighten all bolts and screws to the

recommended torque as outlined in

the Specification Section.
