Adjusting Rear Wheel Toe–in
(Models 30626 & 30630 only)
The rear wheels should not toe–in or toe–out when they are
adjusted correctly. To check the rear wheel toe–in, measure
the center–to–center distance at wheel hub height, in front
and in back of the rear tires. If the wheels toe–in or toe–out,
an adjustment is required.
1. Rotate the steering wheel so rear wheels are straight
ahead.
2. Loosen the jam nuts on both tie rods Adjust both tie
rods until center-to-center distance at front and back of
rear wheels is the same (Fig. 64).
3. When rear wheels are adjusted correctly, tighten jam
nuts against tie rods.

and the wheel hub has end play.
6. Tighten the jam nut to 15–20 in–lbs while rotating the
the wheel hub.
7. Place the nut retainer over the jam nut. If the cotter pin
hole is not aligned with the retainer slot, remove the
retainer nut and reorientate until alignment occurs.

Adjusting the Brakes
Adjust the service brakes when there is more than 1 in.
(25 mm) of “free travel” of the turn pedals, or when the
brakes do not work effectively. Free travel is the distance
the brake pedal moves before braking resistance is felt.
The brakes should only need adjusting after considerable
use. These periodic adjustments can be performed where
the brake cables connect to the brake pedal mount. When
the cables are no longer adjustable, the star nut on the
inside of the brake drum must be adjusted to move the
brake shoes outward. However, the brake cables must be
adjusted again to compensate for this adjustment.
