Adjusting the Rear Wheel
Bearings
1. Jack up rear of machine until wheel is off shop floor.
Use jack stands or block the machine to prevent it from
accidentally falling.
2. Remove dust cap from end of wheel spindle. Also
remove cotter pin retaining slotted nut in place
(Fig. 56).

3. Rotate the wheel by hand and tighten the slotted nut
until the bearing binds slightly. Then loosen nut until
the nearest slot and hole in spindle line up. Install the
cotter pin to retain the slotted nut in place.
4. Install dust cap on end of wheel spindle.
5. Remove jack stands and lower machine to shop floor.
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. 57). 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.
5. Remove wheel nuts and slide wheel and tire assembly
off studs. Rotate brake drum until adjusting slot is at
bottom and centered over star nut that adjusts brake
shoes (Fig. 58).
