BALL ARM

Removal

Remove the steering gear ball arm and the

two screws attaching steering gear to frame.

Remove the four cover capscrews, cover and

lever shaft. Remove the steering gear wheel

and loosen jacket clamp. Slide jacket tube

up and remove the four capscrews on bearing

retainer.

Inspection

Check bearings for wear and roughness.

Check the cam and worm for wear and scor':'

ing. Check the lever shaft bearings for wear.

Steering gear parts must not be worn ex-

cessively or steering adjustment will be

difficult.

Assembly'

Install the worm shaft and adjust bearings to

a free rolling fit without end play or binding

by use of shims between bearing retainer

and housing. Install jacket tube with the

notch in lower end "up" to prevent grease

leakage. Adjust the length of tube to reach

into recess of steering wheel. It must not

touch wheel or it will cause binding.

Back out the lever shaft adjusting screw and

install lever shaft and cover. Count the num-

ber of turns from full right to full left, then

turn back half these turns to mid-position.

At mid-position, adjust mesh between worm

and lever shaft to .001" and secure lock nut.

When placed on the tractor the steering wheel

should have the first spoke to left of cut-out

section straight up or vertical. This places

the cut-out section between the 12

0 IC lock

and four o'clock position where greatest' ad-

vantage in vision is obtained. This adjustment

is made by lengthening one tie rod and

shortening the other as required. Maintain

the "toe-in" of 0" to 1/16" while making this

adjustment. Lubricate the slip joints of socket

and stud rod end to prevent rusting.
