3.
Remove the two screws securing

the neutral start switch to the steering

column and lift the switch from the

column.

Check the column to be sure the

metal switch actuator is secure to the

shift tube and that it is seated as far

forward against the shift tube bearing

as is possible. Also check for a broken

or damaged actuator. If it is broken

or damaged, replace it as shown in

Figure 17.

4.
Before installing a new switch to

the column, check to see that the red

neutral position gauge inserted in the

neutral pinning hole. If the pin is

missing, align the two holes at the

neutral pinning hole on top of the

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 drill size as the thread

01).
For example, use a 5/16-inch

drill for a 5/16-18 thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

paired. Thus, the special tap marked

5/16-18 will not cut the same thread

as a standard 5/16-18 tap. It does cut

a thread large enough to accommo-

date the insert, and after the insert is

installed the original thread size

(5/16-18) 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.

Press the insert against the face of

the tapped hole. Turn the tool clock-

wise and wind the insert into the hole

until the insert is 1/2 turn below the

face.

4.
Working through the insert, bend

the insert tang straight up and down

until it breaks off at the notch.

5.
If the inserts are not properly in-

stalled, they can be removed with the

extractor tool. Place the extractor tool

in the insert so that the blade rests

against the top coil 1/4 to 1/2 turn

away from the end of the coil. Tap

the tool sharply with a hammer so

that the blade cuts into the insert.

unterclockwise. It should rotate count-

erclockwise (viewed from the rear)

with a slight drag, and it should lock

up when attempting to rotate it in a

clockwise direction.

Installation—Center Support

not Chamfered

1.
Install the center support and the

rear band in the case.

2.
Install the primary sun gear, rear

thrust bearing race, needle bearing

and front thrust bearing race if used

in the planet carrier using petroleum

jelly to retain them in place.

3.
Lubricate the bearing surface of

the center support, the rollers of the

planetary clutch, and the cam race in

the carrier with vaseline.

i. Install the^ planetary clutch on

the center support with the saw teeth

of the clutch cage pointing in the

clockwise direction as viewed from the

rear (Fig. 56). Make sure that all roll-

ers are in the cage.

5.
Position the planet carrier on the

support so that the cams in the carrier

engage the saw teeth on the clutch

cage.

6. Push the planet carrier forward

until the rollers are felt to contact the

surface of the cam race.

7.
While applying forward pressure

on the carrier, rotate it counterclock-

wise as viewed from the rear. This will

cause the rollers to roll toward the

large opening end of the cams in the

race,
compressing the springs slightly,

so that the rollers will enter the cams.

8. Some rollers may become

cocked preventing their entry into the

outer race. These rollers must be posi-

tioned individually with a small screw-

driver by pushing the rear of the roll-

ers toward the transmission and into

the cam race (Fig. 56). Keep pressure

applied to the carrier at all times.

9. After all of the rollers have been

started into the cam race, rotate the

carrier counterclockwise while pushing

it forward. Again, straighten any roll-

ers which still may be in a cocked po-

sition and prevent the carrier from

sliding onto the support.

10.
Make sure that all springs are

entered in the cam race before at-

tempting to push the carrier on the

support. Push the carrier all the way

forward and check the operation of

the clutch by rotating it in a counte-

rclockwise direction. The carrier

should rotate counterclockwise with a

slight drag and should lock up when

attempting to rotate it in a clockwise

direction.

11.
Install the selective thrust wash-

er on the pinion carrier rear pilot. If

the end play was not within specifica-

tions when checked prior to disassem-

bly, replace the washer with one of

proper thickness. Refer to the Specifi-

cation Section of Group 7 for selective

thrust washer thickness.procarmanuals.com
