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.

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
for the size of the thread being re-
