Adjusting The Rear Wheel Bearings; Adjusting The Brakes - Toro Groundsmaster 328-D 30630 Operator's Manual

Adjusting the Rear Wheel
Bearings
1. Jack up the rear of the machine until the wheel is
off the floor. Use jack stands or block the
machine to prevent it from accidentally falling.
2. Remove the dust cap from end of the wheel
spindle. Also remove the cotter pin that keeps the
slotted nut in place (Fig. 43).

3. Rotate the wheel by hand and tighten the slotted
nut until the bearing binds slightly. Then loosen
the nut until the nearest slot and hole in the
spindle line up. Install the cotter pin to keep the
slotted nut in place.
4. Install the dust cap on the end of the wheel
spindle.
5. Remove the jack stands and lower the machine to
the floor.

Adjusting the Brakes

Adjust the service brakes when the turn pedals have
more than 25 mm of " free travel", or when the brakes
don't work effectively. Free travel is the distance the
brake pedal moves before you feel braking resistance.
The brakes should only need adjustment 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 the turn pedals—tighten
the brakes—loosen the front nut on the threaded
end of the brake cable (Fig. 44). Then tighten the
rear nut to move the cable backward until the
turn pedals have 13 to 25 mm of free travel.
Tighten the front nut after brakes are adjusted
correctly.

2. When the brake cable cannot get free travel
within 13 to 25 mm, the star nut inside the brake
drum must be adjusted. However, before
adjusting the star nut, loosen the brake cable nuts
to prevent unnecessary strain on the cables.
3. Loosen the five wheel nuts holding the wheel and
tire assembly on the wheel studs.
4. Jack up the machine until the front wheel is off
the floor. Use jack stands or block the machine to
prevent it from falling accidentally.
5. Remove the wheel nuts and slide the wheel and
tire assembly off the studs. Rotate the brake
drum until the adjusting slot is at the bottom and
centered over the star nut that adjusts the brake
