STEERING LEVERS (Cont’d)

Adjusting Lever Freeplay

Read this adjustment completely to become familiar with
the procedure before beginning the adjustment.

Use the following procedure to adjust the steering linkage
so both steering levers have no free play against the
cam. To remove the free play, move the right cam to
match the left cam so there is no free play between the
two cams in the pocket of the detent bracket [C]. Use the
following procedure to adjust the the cam free play.

1. Only the right side cam is adjustable in slotted hole

in bellcrank (Item 1) [B]. The left side cam is fixed
and will not require adjustment. The cam should not
rotate on the mounting bolt. If cam rotates, tighten
the jam nut (Item 1) [A] against the cam while
holding cam mounting bolt (Item 3) [A].

2. Loose the cam mounting bolt nut (Item 2) [A] and

move the cam to the rear to get free play in the left
hand lever.

3. Tighten the cam bolt. Use a punch and hammer, hit

the cam nut (cam mounting bolt is still tight) until the
free play is removed from the left hand lever [B].
The cam must be centered in the detent bracket
pocket [C].

4. Recheck the torque at the cam bolt to be sure it is

still tight. Check again to be sure there is no free play
in the cams. If there is any free play the neutral
setting can not be obtained.

STEERING LEVERS (Cont’d)

Adjusting The Wheel RPM Forward Compared To
Reverse Travel

Read this adjustment completely to become familiar with
the procedure before beginning the adjustment.

1. Disconnect the two bolts of the pintle links (both

sides) (Item 1) [A].

2. Fully lower steering lever stop and tighten (both

sides) (Item 1) [B].

3. Move the lever to full forward,  measure the distance

from the U–bolt to the lock nut. Record this
measurement [C].

EXAMPLE ONLY: 3.66 inch (82,0 mm)

4. Move the lever to full reverse, measure the distance

from the U–bolt to the lock nut. Make a record of this
measurement [D].

EXAMPLE ONLY: 2.76 inch (70,0 mm)

NOTE: Before measuring, move the steering lever a

small amount to be sure the cam is in the
detent pocket with no freeplay.

NOTE: This procedure adjusts the position of the

steering levers in the panel when in neutral.
Levers centered in steering panel give equal
travel forward compared to reverse.

STEERING LEVERS (Cont’d)

Adjusting The Wheel RPM Forward Compared To
Reverse Travel (Cont’d)

5. Move the lever to the neutral position. Measure the

distance from the U–bolt to the lock nut [A]. Neutral
must be adjusted to 3.21 inch (82 mm) per example.

EXAMPLE:

Forward

   3.66 inch (93,0 mm)

Reverse

– 2.76 inch (70,0 mm)
   0.90 inch (23,0 mm) Total Travel*

Divided by Two =0.45 inch (11,0 mm) Half the Travel

+2.76  inch (70,0 mm) Reverse Travel
3.21 inch (82,0 mm) Is Neutral

If adjustment is required, loosen the mounting bolts (Item
1) [B].

Moving the neutral spring bracket up will allow more
forward stroke and more forward wheel RPM. Moving it
down will allow more rearward stroke and more reverse
wheel RPM.

Use a screwdriver to move the neutral spring bracket
(Item 1) [C] down or a  large pliers to move it up in its
slotted holes.

Tighten the mounting bolts on the spring bracket (Item 1)
[B].

Neutral to forward cable travel must be within 0.010 inch
(0,25 mm) left compared to right side.

Install pintle link bolts (Item 1) [D] (both sides).

NOTE: Keep the bracket vertical to be sure that the

cams make full contact in the pocket of the
detent bracket.

STEERING LEVERS (Cont’d)

Adjusting The Steering Neutral Setting

Read this adjustment completely to become familiar with
the procedure before beginning the adjustment.

NOTE: The  following adjustments (Steps a, b, c & d)

are not necessary if the thread engagement
in the ball joint is equal on both ends of the
cable (Item 1) [A] & [B].

a.

Disconnect the cable ball joint from the steering
lever shaft (Item 2) [A].

b.

Loosen the jam nut and turn the ball joint all the
way  to  the  end  of  the threads (toward cable
housing).

c.

At the pumps, loosen the jam nut and turn the
inner cable until the ball joint is all the way to the
end of the threads (toward the cable housing).

d.

Connect the steering cable ball joint.

1. Start the engine. WHEN THE ENGINE IS

RUNNING, THE WHEELS WILL BE TURNING.

2. The steering cable ends have right and left hand

threads. By turning the inner cable, it will shorten or
lengthen the cable. Turn the inner cable until the
wheels stop turning [C].

NOTE: This procedure adjusts the creep (wheel

movement in neutral) and dead–band (lever
travel before wheels start to turn). Adjusting
steering cable length will match lever neutral
and pump neutral.

NOTE: Before measuring, move the steering lever a

small amount to be sure the cam is in the
detent pocket with no freeplay.

3. Use a straight edge for a measuring reference point

positioned against the pedal lock links (Item 1) [D].
Put a ruler between reference and steering lever to
measure lever travel from neutral until wheel starts
to travel forward. Then measure from neutral until
wheel starts to travel reverse [D].

4. Adjust cable length by turning the inner cable until

the two measurements are equal [C]. Tighten the
jam nut (both ends).

5. Repeat the procedure for the other side of the

loader.

Put jackstands under the front axles and rear
corners of the frame before running the engine
for service. Failure to use jackstands can allow
the machine to fall or move and cause injury or
death.
