E. Start the machine and set the throttle to about
1/3 open position.
When the machine is running, you could be
caught and injured in moving parts or burned
on hot surfaces.
Stay away from pinch points, moving parts,
and hot surfaces when adjusting the running
machine.
F. Have a helper hold the traction control tight to
the reference bar in reverse.
G. Adjust the length of the traction rods until both
tracks are running at the same speed.
Note:
You can also adjust the maximum reverse
speed of the tracks at this time.
H. Tighten the jam nuts.
I. Adjust the traction control so that it rests flush
against the reference bar when it is pulled straight
back (Figure 53 and Figure 54).
J.
Tighten the flange nut and bolt in the traction
control stem.
K. Stop the engine and lower the machine to the
ground.
L. Drive the machine in full reverse, checking to
see if the unit tracks straight. If it does not,
note the direction the machine veers. Repeat the
adjustment previously described so that it tracks
straight in reverse.
Adjusting the Traction Control
Neutral Position
If the machine creeps forward or backward when the
traction control is in neutral and the unit is warm, the
return-to-neutral mechanism on the pumps may need
to be adjusted; contact you Authorized Service Dealer
for repairs.
Adjusting the Tracking of the
Traction Control, Full Forward
Position
If the machine does not drive straight when you hold
the traction control forward against the reference bar,
complete the following procedure:
1. Drive the machine with the traction control against
the reference bar, noting which direction the
machine veers.
2. Release the traction control.
3. If the machine veers to the
left
, loosen the
right
jam
nut and adjust the tracking set screw on the front of
the traction control (Figure 56).
4. If the machine veers to the
right
, loosen the
left
jam
nut and adjust the tracking set screw on the front of
the traction control (Figure 56).

straight in the full forward position.
Important:
Ensure the tracking set screws
touch the stops in the full forward position to
avoid over stroking the hydraulic pumps.
