SECTION 4 - SERVICE
4.4 TRACTION CONTROL NEUTRAL
ADJUSTMENT
The Traction Control Neutral Adjustment
procedure is sensitive. The following steps and
WARNINGS must be followed very carefully.
WARNING
9. Wheel rotation will be stopped by adjusting the
eccentric on the pump arms on the right and left
pumps. Turning the eccentric slightly clockwise or
counter-clockwise will synchronize the pump and
traction controls for Neutral. See Figure 3.11. To
turn the eccentric, first loosen the bolt in the pump
control arm and the nut and bolt fastening the
eccentric to the pump control arm. With both
Traction Levers latched in Neutral, start engine.
Turn eccentric slightly clockwise or counter-
clockwise until wheels stop rotating. Tighten control
arm bolts and eccentric nut and bolts. Check for
wheel rotation. Repeat eccentric adjustment if
needed.
IMPORTANT: To complete this procedure a steel
rod 5/16" diameter and 20" long will be required.
DO NOT begin this procedure without it.
1. Place machine on smooth level surface. Stop
engine and remove keys.
2. Raise rear of machine just high enough for rear
wheels to clear ground. Block machine securely.
3. Latch both Traction Levers in Neutral.
4. Insert rod (5/16" diameter x 20" long) through
alignment holes in the left and right traction control
shift lever arms and the tank support bracket. The
rod should pass through both the left and right
traction control shift lever arms. See Figure 3.9.
5. Disconnect left & right swivels from the left and
right traction control arms and loosen swivel jam
nuts. See Figure 3.8.
6. Adjust swivel (Clockwise or Counter-Clockwise)
until the pin on the swivel aligns perfectly with the
hole in the traction control arm. The Traction Lever
must be held in the Neutral Latch position when
making this adjustment. Complete this adjustment
for both left and right swivels. Carefully reattach
and secure swivels to control arms. Tighten swivel
jam nuts. IMPORTANT: Both the left and the right
swivels must be installed in the same traction
control arm speed range setting. Mid range
(middle hole) setting is recommended.
7. Remove steel rod from shift lever arms.
8. Check to insure machine is securely blocked.
Start engine. Drive wheels should not rotate with
both Traction Levers latched in the Neutral
position. If no rotation is observed the adjustment
procedure is complete. If wheels do rotate proceed
to next step. STOP ENGINE.
