CAUTION
The extension spring is under tension and may
cause personal injury during installation. Use
caution when installing spring to the pump arm.
2. Attach extension spring to anchor point of arm. Tight-
en lock nut on adjustment pin to allow from .475” to .725”
(12.1 to 18.4 mm) thread length to extend beyond the
lock nut (Fig. 44).
3. If ball joint was removed from traction rod, install ball
joint so that distance from center of ball joint stud to cen-
ter of bearing is from 14.050” to 14.170” (35.7 to 36.0
cm) (Fig. 45).
4. Secure traction rod to pump lever with cap screw, flat
washer and lock nut.
5. Make sure that traction neutral switch connector is
plugged into machine wire harness.
6. Check and adjust neutral position (see Operator’s

WARNING
Before raising the machine, review and follow
Jacking Instructions in Chapter 1 – Safety.
A. Raise machine so front wheel and one rear wheel
are off the ground and can rotate freely. Support ma-
chine with jackstands or wooden blocking. Chock the
rear wheel on the ground to prevent it from rotating.
CAUTION
Use extreme caution because the rear wheel on
the ground will be trying to move the machine
rearward.
B. Start engine and depress traction pedal fully in
the reverse direction. Using a phototac, check that
rear wheel speed is from 135 to 180 RPM.
C. If necessary, adjust ball joint on traction rod to
provide rear wheel speed from 135 to 180 RPM.
D. With engine stopped, depress traction pedal fully
in the forward direction and check that pump lever is
rotated fully. Also check that clearance between ped-
al hub and pedal stop is from 0 to .120” (3 mm). Ad-
just stop if necessary (see Operator’s Manual).
9. Position center shroud to machine and secure with
two (2) cap screws and flat washers (Fig. 46).
