Adjusting Steering Stops
(Models 30627 & 30631 only)
The rear axle steering stops help prevent over travel of the
steering cylinder in case of impact on rear wheels. The
stops should be adjusted so there is .090 inch clearance
between the bolt head and the knuckle on the axle when the
steering wheel is completely turned left or right.
1. Thread the bolts in or out until the .090 inch clearance
is attained (Fig. 66).

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.
