Front Wheel Alignment - Toro Workman 3000 Series Service Manual

Front Wheel Alignment

1. Before inspecting or adjusting front wheel alignment,
check that when fully retracted, the steering cylinder has
a length as shown in Figure 17. If the retracted cylinder
length is incorrect, see Steering Cylinder Installation in
Service and Repair section of Chapter 9 -- Hydraulic
System for steering cylinder ball joint installation proce-
dure.
2. With steering cylinder mounted in vehicle, rotate
steering wheel to extend steering cylinder to a length of
17.320" (43.99 cm) between the centers of the cylinder
ball joints (Fig. 18). This steering cylinder length will cen-
ter the Pitman arm with the vehicle to ensure correct
front wheel alignment measurement.
3. With the Pitman arm centered, measure center to
center distance (at axle height) between the front
wheels at both front and rear of the wheels (Fig. 19). The
front measurement must be 0.125 to 0.375 inch (3.18 to
9.53 mm) greater than the rear measurement (toe--out).
4. If adjustment is needed, loosen jam nuts on front tie
rod ends and rotate tie rod(s) to change alignment.
Torque jam nuts to 50 ft--lb (68 N--m) after adjustment is
complete. Make sure that the tie rod ends are aligned
with each other as the jam nuts are being tightened.
5. After alignment has been checked and/or adjusted,
check for component interference as steering wheel is
turned from lock to lock.
A. If a tie rod contacts the Pitman arm, adjust steer-
ing cylinder ball joint location.
B. If tie rod ends contact spindles, adjust both tie
rods equally to re--center steering.
C. After any adjustment, re--check front wheel align-
ment. Additionally, make sure that all jam nuts are
properly torqued.
