Replacing the Alternator Belt

Squealing when the belt is rotating, frayed belt edges,
burn marks and cracks are signs of a worn belt.
Replace the alternator belt if any of these conditions
are evident.
1. Stop the engine, set the parking brake, remove
the key and disconnect the spark plug wire(s)
from the spark plug(s).
2. Remove the PTO drive belt. Refer to Replacing
the PTO Drive Belt, on page 57.
3. Loosen both upper and lower alternator bolts to
allow alternator to rotate and loosen belt
(Fig 55).
4. Remove belt from pulley, alternator and over
clutch pulley (Fig 55).
5. Install new belt.
6. Rotate alternator out away from engine and
tighten lower and upper aletnator bolts (Fig 55).
Note: Alternator belt will deflect 1/8" while
applying 5–7 pounds of force, when
installed correctly.

Replacing the Grass Deflector

1. Remove the locknuts, bolts and springs holding
the deflector mounts to the pivot brackets
(Fig. 56).
2. If the pivot brackets need to be replaced, remove
the carriage bolts and cone locknuts holding the
old brackets to the top of the discharge opening,
then install the replacement pivot brackets. Make
sure the carriage bolt heads are on the inside of
the cutting unit (Fig. 56).
3. Install the deflector mounts onto the pivot
brackets with the bolts, springs and locknuts.
Make sure the straight ends of the springs are
positioned between the deflector mounts and the
grass deflector (Fig. 56).
4. Tighten the locknuts until they contact the pivot
brackets (Fig. 56).
IMPORTANT: The grass deflector must be
spring-loaded in the down position. Lift the
deflector up to test that it snaps to the full
down position.
