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-

with the repair kit marked 5/16-18

will not cut the same thread as a

standard 5/16-inch tap. It will cut a

thread large enough to accommodate

the insert, and after the insert is in-

stalled, the original thread size (5/16-

18 inch) is restored.

3.
Select the proper coil inserting

tool. These tools are marked with the

thread size being repaired. Place the

insert on the tool and adjust the sleeve

to the length of the insert being used.

CONTROL VALVE BODY

Disassembly

1.
Remove the nine screws that at-

tach the screen to the lower valve

body and remove the screen and gas-

ket (Fig. 36).

2.
Remove the twelve screws and

the 2 plates that attach the two valve

bodies.

3.
Separate the bodies and remove

the separator plate and gasket. Be

careful not to lose the check valves

and springs.

4.
Depress the manual valve detent

spring with the tool shown in Fig. 37.
Remove the retaining pin from the

upper valve body. Remove the spring

and detent plunger.

5.
Slide the manual valve (Fig. 38)

out of the valve body.

6. Cover the downshift valve port

with a finger, then working from the

underside of the body remove the

downshift valve retainer. Remove the

spring and downshift valve.

7.
Apply pressure on the pressure

booster valve retaining plate and re-

move the two attaching screws. Slowly

release the pressure and remove the

plate, sleeve and the pressure booster

valve. Remove the two springs and the

main regulator valve from the same

bore.

8. Apply pressure on the throttle

booster valve retaining plate and re-

move the two attaching screws. Slowly

release the pressure and remove plate,

throttle booster valve and spring, and

the manual low 2-1 scheduling valve

and spring from the body.

9. Apply pressure on the remaining

valve retaining plate and remove the

eight attaching screws.

10.
Hold the valve body so that the

plate is facing upward. Slowly release

the pressure and remove the plate.

11.
When removing the various

valves from the control valve body,

keep all ports covered with your fin-

gers except the bore the valve is being

removed from. Remove the spring and

the intermediate servo modulator valve

(Fig. 38) from the valve body.

12.

Remove the 3-2 shift timing

valve retainer and remove the plug.

Remove the 3-2 shift timing valve and

spring to complete the disassembly of

the control valve. Do not remove the

3-2 shift timing valve plug if it is

found to be peened, preventing the re-

moval of the plug and the 3-2 shift

timing valve. This condition will not

affect transmission operation and is

not cause for replacement of the main

control. The 3-2 shift timing valve is

non-functional and removal of the

plug, 3-2 shift timing valve and spring

is not required.

Assembly

1.
Place the spring 3-2 shift timing

valve and plug in the valve body if

they were previously removed. Install

the plug retainer.
