FIG. 56—Checking Differential

Torque

High Torque

a. Insufficient lubricant on the

clutch plates.

b.
A clutch plate wedged in be-

tween the case halves.

c. An improperly centered Belleville

spring.

Low Torque

a. Weak Belleville spring.
b.
Improper amount of clutch

plates installed.

Under no circumstances should the

Belleville spring be ground down to

reduce torque. The torque required to

keep the side gear turning with new

clutch plates is 155 to 195 ft-lbs. On

reused clutch plates, the torque re-

quired is 75 ft-lbs minimun.

7.
If the differential bearings have

been removed, press them on as

shown in Figs. 49 and 50.

8. Install the side bearings on the

differential case, and install the case

in the carrier as described in steps 7

through 16 under Assembly and In-

stallation of Conventional Differential

Case. Adjust and check backlash be-

tween the ring gear and pinion as di-

rected under Differential Bearing Pre-

load Adjustments.

ASSEMBLY OF

TRACTION-LOK

DIFFERENTIAL CASE

1.
Lubricate all parts with Ford

Hypoid Lubricant (Ford Part No.

C6AZ-19580-C), during assembly of

differential.

2.
Mount the differential case in a

soft jawed vise and place a side gear

thrust washer and side gear in the

counterbore of the case.

. 57—Center Block and Pre-Load Springs Installation
3.
Install the pinion thrust washers

and place the pinion gears on the side

gear; aligning the holes in the washers

and gears with the holes in the case.

4.
Install the center block so that

the shaft holes are aligned with the

holes in the pinion gears and case.

The center block has two machined

sides and two rough sides.

5.
With a brass drift, drive in the

long pinion shaft from the outside of

the case aligning the lock pin holes in

the shaft with the holes in the case.

The center block should be positioned

so the long shaft is driven through the

rough side and short shafts driven

through the machined side (Fig. 57).

6. With a suitable drift, install the

shaft lock pins. Make sure the pinion

and side gears move freely.

7.
Place the four pre-load springs in

the holes provided in the center block.

8. Position a pre-load plate over the

four springs, making sure the springs

are properly seated. The pre-load

plate straddles the center block over

its narrower or machined width.

9. Mount the differential cover in a

soft jawed vise or holding fixture.

10.
Insert shim(s) of 0.050 total

thickness in the cover cavity.

11.
Install the composite plate (fric-

tion material on one side and steel on

the opposite) on the back side of the

clutch hub with the friction material

against the hub; next, install a friction

plate, then steel, friction, stee, fric-

tion, steel, friction, and lastily a steel

plate (Figures 3 and 58). When new

clutch plates are used, soak the plates

in Ford Hypoid Lubricant (Ford Part

No.
C6AZ-19580-C), or equivalent lu-

bricant, for approximately 30 minutes

before installation.

12.
Place the clutch hub with the

clutch plates into the clutch ear cavi-

ties in the differential cover. Make

sure that the splines on the last fric-

ion plate are engaged on the hub.

13.
Obtain locally a 5/8 inch x

2 1/2 inch or 9/16 inch x 2 1/2

inch bolt, nut and two I 1/2 inch

outside diameter flat washers approx.

1/8 inch in thickness. These parts are

required to compress the clutch pack

in order to obtain the proper shim

selection.

Install a flat washer on the bolt,

and place the bolt through the clutch

hub.
Hold the bolt in position and

turn the cover over. Place a flat wash-

er on the bolt and then install the nut.

Be sure the washers are centered, and

torque the nut 10 to 15 ft-lbs (Fig.

59).

14.
Place the shim template tool

(Ford Tool No. T68P-4946-A) in the

clutch hub. Some clearance should beprocarmanuals.com
