75–100 in–lbs using a hand wrench.
4. Turn the wheel hub to seat the bearings.
5. Loosen the jam nut until it is away from the flatwasher
and the wheel hub has end play.
6. Tighten the jam nut to 15–20 in–lbs while rotating the
the wheel hub.

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.
1. To reduce free travel of turn pedals—tighten the
brakes—loosen front nut on threaded end of brake cable
(Fig. 44). Then tighten rear nut to move cable backward
until turn pedals have 1/2 to 1 in. (13 to 25 mm) of free
travel. Tighten front nut after brakes are adjusted
correctly.

2. When adjustment of brake cable cannot get free travel
within 1/2 to 1 in. (13 to 25 mm), the star nut inside the
brake drum must be adjusted. However, before
adjusting the star nut, loosen brake cable nuts to prevent
unnecessary strain on the cables.
3. Loosen five wheel nuts holding wheel and tire assembly
on wheel studs.
4. Jack up machine until front wheel is off the shop floor.
Use jack stands or block the machine to prevent it from
falling accidentally.
