F ree tra v el is the distance the brak e pedal mo v es
before braking resistance is felt.
T he brak es should be c hec k ed for adjustment after
the first 10 hours of operation and should only
need adjusting after considerable use thereafter .
T hese periodic adjustments can be perfor med
where the brak e cable connects to the bottom of
the brak e pedals . W hen the cable is no long er
adjustable , the star n ut on the inside of the brak e
dr um m ust be adjusted to mo v e the brak e shoes
outw ard. Ho w ev er , the brak e cables m ust be
adjusted ag ain to compensate for this adjustment.
1. Diseng ag e the loc k ar m from the right brak e
pedal so that both pedals w ork inde pendently
of eac h other .
2. T o reduce the free tra v el of the brak e pedals ,
tighten the brak es b y loosening the front n ut
on the threaded end of brak e cable ( Figure 58 ).
T hen tighten the rear n ut to mo v e cable
bac kw ard until the brak e pedals ha v e 1/2 to 1
inc h (13 mm to 25 mm) of free tra v el.

Belt Maintenance
Checking the Alternator
Belt
Chec k condition and tension of belts ( Figure 59 )
after ev er y 150 operating hours .
1. Proper tension will allo w 3/8 inc h (10 mm)
deflection when a force of 10 lb is applied on
the belt, midw a y betw een the pulleys .
2. If the deflection is not 3/8 in. (10 mm), loosen
the alter nator mounting bolts .

3. Increase or decrease the alter nator belt tension
and tighten the bolts .
4. Chec k the deflection of the belt ag ain to ensure
that the tension is cor rect.
Servicing the PTO Belt
Checking the PTO Belt Tension
1. T ur n the engine off , set the parking brak e , and
remo v e the ignition k ey .
2. Raise the engine hood and allo w the engine to
cool.
3. Loosen the tensioning rod jam n ut ( Figure 60 ).
