Adjustment of the traction linkage should be checked
whenever traction drive components are replaced or re-
moved.
Assembly Adjustments
1. Traction pedal stop should be 1.500" (38 mm) above
platform bracket (item 1 in Fig. 53). If necessary, loosen
jam nuts and adjust stop location. Make sure that both
jam nuts are tightened to secure adjustment.
2. On traction pump end of traction rod, rod end should
be installed so that distance from end of traction rod to
center of rod end is 1.140" (29 mm) (item 3 in Fig. 53).
Tighten jam nut to secure rod end to traction rod.
3. On traction lever end of traction rod (item 4 in Fig.
53), jam nuts should position traction rod so traction
pedal remains in the neutral detent position and is at an
o
approximate 56 angle. Use a magnetic protractor to
check pedal angle.
4. With ignition switch in the ON position (engine not
running), use Diagnostic Display to make sure that neu-
tral switch is closed when traction pedal is released to
the neutral detent position (see Diagnostic Display in the
Troubleshooting section of Chapter 5 -- Electrical Sys-
tem).
5. The traction pedal should contact the pedal stop
when fully depressed. At this point, the piston pump
should be at full stroke.
6. To check and adjust neutral position:
A. Make sure hydraulic oil is at normal operating
temperature by operating the machine under load for
approximately ten (10) minutes.
CAUTION
All wheels will be off the ground and rotating
when checking neutral position. Make sure ma-
chine is supported so it will not move and acci-
dentally fall to prevent injuring anyone near the
machine.
B. Raise and support machine so all wheels are off
the ground (see Jacking Instructions in Chapter 1 --
Safety).

C. When traction pedal is released from either for-
ward or reverse, pedal should return to the neutral
position and wheels should stop rotating.
D. If necessary, adjust spring shaft (item 5 in Fig. 53)
until neutral operation is correct.
E. Lower machine to ground.
7. After adjustments have been made and all fasteners
are tightened, make sure that traction rod does not con-
tact anything through both forward and reverse direc-
tions.
