DRIVE SHAFT TESTS

DRIVE LINE BALANCE CHECK

If detailed parts
of the
drive shaft

are replaced
and
shaft vibration
is en-

countered after installation, disconnect

the shaft
at the
slip yoke. Rotate
the

slip yoke
180
degrees; then, reconnect

the shaft
to the
slip yoke.
If the
vibra-

tion persists, disconnect
the
shaft
at

the rear axle companion flange.
Ro-

tate
the
companion flange
180
degrees

and reconnect
the
shaft
to the
flange.
DRIVE LINE ANGLE CHECK

Vibration
or
"shudder" which
is no-

ticeable either
on
fast acceleration
or

when coasting, using
the
engine
for a

brake,
may be
caused
by the
rear axle

housing being loose
on the
rear

springs
or by
improper pinion angle.

Refer
to
Group
3,
Part
2 for
pinion

angle checking procedures.
If the
rear

axle U-bolts (Fairlane, Montego,

Mustang, Cougar, Falcon models
only)
are
loose, torque
the
nuts
to

specification.

DRIVE SHAFT RUNOUT CHECK

Using
a
dial indicator, check
the

runout
at
each
end and in the
middle

of
the
driveshaft.
The
rear check

should
be
made
on the
small tube
sec-

tion
of the
shaft between
the
balance

weights
and the
yoke welds. Drive-

shaft runout should
not
exceed 0.035

inch
at any one
point.

DESCRIPTION

The drive shaft
is the
means
of

transferring power from
the
engine,

through
the
transmission,
to the dif-
ferential
in the
rear axle,
and
then
to

the rear wheels.
The
drive shaft incor-

porates
two
universal joints
and a
slip
yoke
(Fig. 1) or two
double cardan

universal joints,
one at
each
end of the

shaft (Figs.
2 and 3).

FLYWHEEL HOUSING ALIGNMENT

Alignment of the flywheel housing

bore and rear face with the engine

should be checked as a possible cause

of any of the following troubles- ex-

cessive transmission gear wear, ..ans-

mission jumping out of gear, especial-

ly third gear, drive line vibration, ex-

cessive pilot bushing wear, noisy re-

lease bearing, or excessive clutch spin

time.

INSPECTION

1. With the clutch release bearing

removed, install the indicator pilot

tool shown in Fig. 1.

2.
Clean the faces of the flywheel

housing bolt bosses, and remove all

burrs, nicks, and paint from the

mounting face of the housing.

3.
Install the dial indicator on the

pilot and adjust the holder so the but-

ton will contact a circumference just

inside of the transmission mounting

holes.

4.
Push the flywheel forward to re-

move crankshaft end play. Set the dial

indicator face to read zero.

5.
Remove the spark plugs to alle-

viate compression.

6. Pull the engine crankshaft

through one revolution. The crank-

shaft must be held in the forward po-

sition while rotating it.

7. Note the indicator reading and

mark the maximum point of runout

on the face of the housing (Fig. 1).
8. Position the dial indicator to

check bore alignment (Fig. 1). The

bore must be clean and free of burrs,

nicks and paint.

9. Pull the crankshaft through one

revolution. Note the indicator reading

and mark the maximum point of run-

out on the face of the housing as

shown in Fig. 1.

10.
Remove the dial indicator from

the crankshaft and the housing.

11.
Select the Dia-L-lgner pilot

(Fig. 2) which will fit snugly in the

bore of the flywheel housing.

12.
Press the pilot into place on the

locator on the back of the dial.
13.
Position the Dia-L-lgner on the

face of the housing (Fig. 3) with the

pilot in the bore.

14.
Rotate the face runout arrow to

the positive face runout mark on the

housing.

15.
Without moving the face runout

arrow, rotate arrow A until it is at the

negative bore reading.

16.
Slide arrow A to register the

amount of bore runout on the .010-

line of the white scale. Use the

scale No. to coincide with the pilot

being used.

in the direction of the face runout

arrow and its center line is parallel to

the center line of the face runout

arrow.

18.
Determine the amount of the

face runout on the B arrow scale.

19.
The value of the circular line

beneath the amount of face runout

will be the desired reading. If the

reading is in excess of 0.014 inch the

housing alignment is unacceptable.

20.
Remove the Dia-L-lgner gauge

from the flywheel housing.

21.
Install the spark plugs and con-

nect the wires.

ENGINE IN VEHICLE

Since any change in face alignment

will change bore alignment, it may be

possible to correct bore alignment by

changing face alignment. Face align-

ment can be changed by shimming be-

tween the flywheel housing and en-

gine.
Fig. 4 shows the type of shim

which can be fabricated.

Not more than 0.010 inch thickness

shims may be used between the fly-

wheel housing and engine. If a 0.010-

inch shim will not bring face and bore

alignment within limits, replace the

flywheel housing.

The shim required is one half the

maximum (—) indicator reading, and

should be located at the point of max-

imum minus (—) indicator reading.

If both the bore and face alignment

are out of limits, shim between the

flywheel housing and engine to bring

face alignment within limits. Check

the bore alignment.

If the bore alignment is out of lim-

its and the face alignment is within

limits,
shim the flywheel housing to

the limit of face misalignment and

check the bore alignment. If it is not

within limits, replace the housing.

ENGINE OUT OF VEHICLE

The same procedure to correct

alignment may be used with the en-

gine out of the vehicle or in the vehi-

cle,
up to the point of replacing the

flywheel housing. If the bore align-

ment cannot be brought within limits

by shimming, follow this procedure:

dure:

1.
Remove the flywheel housing

from the engine and remove the dowel

pins.
Install the flywheel housing and

tighten the attaching bolts.

2.
Install the dial indicator (Fig. 1).

Check the face alignment, and shim as
C2068-A

. 3—Dia-L-lgner Gauge Installed

required to bring face alignment with-

in limits.

3.
Position the indicator to check

the bore alignment. If the bore align-

ment is not within limits, reduce the

tension on the flywheel housing at-

taching bolts so that the housing can

be moved by striking it with a lead

hammer or a block of wood and a

steel hammer.

4.
The lateral alignment should be

brought within limits so that an indi-

cator reading is within limits between

the 9 o'clock and the 3 o'clock posi-

tions on the bore circle. When the lat-

eral alignment is within limits the

housing usually can be moved straight

up or down without disturbing the lat-

eral alignment. When alignment is

within limits, torque the housing bolts

and recheck bore alignment.

5.
If the flywheel housing cannot be

moved enough to bring the alignment

within limits, mark the holes restrict-

ing movement, and then remove the

housing and drill the marked bolt

holes 1/32 inch larger.

6. When the flywheel housing bore

alignment is within limits and the at-

taching bolts are at normal torque,

hand ream the dowel pin holes 1/32

inch larger. Use a straight reamer and

ream from the flywheel housing side.

Oversize dowel pins can be made from

drill rod stock.

7.
Remove the flywheel housing

and then install the oversize dowel

pins in the cylinder block. Complete

the assembly in the usual way.

8. Recheck the flywheel housing

with the Dia-L-lgner gauge to make

sure that the housing is within the spe-

cified limits.procarmanuals.com

CLEANING AND INSPECTION

RELEASE BEARING

Wipe all oil and dirt off the release

bearing. The bearing is prelubricated

and should not be cleaned with sol-

vent.

Inspect the bearing retainer for

loose spring clips and rivets.

Inspect the release bearing assembly

for burrs which may cause the assem-

bly to drag on the transmission bear-

ing retainer. Any such burrs should be

cleaned up with fine crocus cloth. If

burrs are found, inspect the transmis-

sion input shaft bearing retainer for

evidence of scoring. Any scoring

should be polished out with crocus

cloth. Coat the bearing retainer with a

thin film of lithium-base grease

(C3VY-19586-A). Prior to release

bearing installation, apply a light film

of lithium base grease (C3VY-

19586-A) on both sides of the release

lever fork where it contacts the release

bearing hub and retaining springs.

Apply a light film of lithium base

grease (C3VY-19586-A) plate to the

release bearing surface that contacts

the pressure plate fingers. Carefully

fill the grease groove inside the bear-

ing hub with lithium base grease (no

polyethylene). Clean all excess grease

from the bore of the bearing hub. Ex-

cess grease will be forced onto the

spline by the transmission input shaft

bearing retainer and will contaminate

the clutch disc. Also, care must be

exercised when applying lubricants to

the release bearing, release bearing

hub and the release lever fork to avoid

excessive grease from contaminating

the clutch disc.

Hold the bearing inner race and ro-

tate the outer race while applying

pressure to it. If the bearing rotation

is rough or noisy, replace the bearing.

Most release bearing failures are

caused by improper clutch pedal ad-

justments. If the clutch linkage does

not have enough free travel, the re-

lease bearing will constantly touch the

release fingers and will spin whenever

the engine is running.

When installing a release bearing on

vehicles equipped with separate hub

and bearing, use the tool shown in

Fig. 5.

Release bearing failure can be

caused by the release lever contact

points being out of plane. Check the

wear on the release bearing assembly

where the release lever contacts it.

If one side of the assembly shows

more wear than the other, the release
lever is bent out of plane, or is not

centering on the bracket on the fly-

wheel housing.

Misalignment between the engine

and transmission can cause release

bearing failure. Other symptoms of

misalignment are transmission jump-

ing out of gear, especially third gear,

drive line vibration; excessive wear in

the pilot bushing, excessive clutch disc

spin time resulting in gear clash, and

excessive transmission gear wear.

PRESSURE PLATE AND COVER

Inspect the surface of the pressure

plate for burn marks, scores, or rid-

ges.
Generally, pressure plate resur-

facing is not recommended. However

minor burn marks, scores, or ridges

may be removed. During the resurfac-

ing process, the flatness of the pres-

sure plate must be maintained. If the

pressure plate is badly heat-checked or

deeply scored, replace the pressure

plate and cover assembly. Clean pres-

sure plate and flywheel surfaces with a

suitable solvent, such as alcohol to be

sure the surfaces are free from any oil

film. Do not use cleaners with petrole-

um base, and do not immerse the

pressure plate in the solvent.

Place the plate on the floor, being

careful not to score or scratch the sur-

face.
Force each individual finger

down, then release quickly. If the fin-

ger does not return quickly, a binding

condition is indicated, and the pres-

sure plate should be replaced.

The pressure plate should be lubri-

cated with a lithium-base grease be-

tween the driving lugs and the edges

of the pressure plate openings, as

shown in Fig. 6. Depress the pressure

plate fingers fully, apply the lubricant,

and then move the fingers up and

down until the lubricant is worked in.

Do not apply excessive lubricant.

CLUTCH DISC

Inspect the clutch disc facings for

oil or grease. Eliminate the source of

any oil or grease before replacing the

disc. An excessive amount of grease in

the pilot bushing or release bearing

hub will find its way to the disc fac-

ings.
Too much lubricant in the trans-

mission or a plugged transmission

vent will force the transmission lubri-

cant out the input shaft and onto the

disc facings. Also, rear main bearing

oil seal leaks or oil leaks from the fly-

wheel mounting bolts can contaminate

the clutch disc.
Inspect the clutch disc for worn or

loose facings. Check the disc for worn

or loose facings. Check the disc for

distortion and for loose rivets at the

hub.
Check for broken springs.

Springs loose enough to rattle will not

cause noise when the car is operating.

Replace the disc assembly if any of

these defects are present. Be especially

careful when installing a new disc to

avoid dropping it or contaminating it

with oil or grease.

PILOT BUSHING

Check the fit of the clutch pilot

bushing in the bore of the crankshaft.

The bushing is pressed into the

crankshaft and should not be loose.

Inspect the inner surface of the bush-

ing for wear or a bell-mouthed condi-

tion. If the bushing is worn or dam-

aged, replace the bushing with a new

service bearing. Refer to the applica-

ble engine for the replacement proce-

dure.
