INSTALLATION

1.
Position a new gasket on the

servo cover.

2.
Position the servo spring on the

piston rod.

3.
Insert the servo piston rod in the

case.
Secure the cover with the attach-

ing bolts, taking care to back off the

band adjusting screw as the cover

bolts are tightened. Make sure that

the vent tube retaining clip and service

identification tag are in place.

4.
Raise the transmission high

enough to install the engine rear sup-

port. Secure the support to the exten-

sion housing with the attaching bolts.

Lower the transmission as required to

install the support to crossmember at-

taching bolt. Torque the attaching

bolts to specification.

5.
Remove the jack.

6. Adjust the band as detailed in

Section 2.

7.
Lower the vehicle and replenish

the fluid as required.

LINCOLN

Removal

1.
Raise the vehicle on a hoist.

2.
Place a drain pan under the

servo.
Remove the bolts that attach

the servo cover to the transmission

case.

3.
Remove the three bolts that at-

tach the manual and downshift control

rod splash shield to the frame side rail

and remove the shield. Remove the

reinforcement plate from under the

transmission oil pan.
4.

Thread Repair-Case

Thread service kits may be pur-

chased from local jobbers or the

Heli-Coil Corporation. To repair a

damaged thread, the following proce-

dures should be carefully followed:

1.
Drill out the damaged threads

using the same size threads as the

thread OD. For example, use a 5/16-

inch drill when repairing a 5/16-18

inch thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked
