Craftsman 917.276310 - Manual (Page 23)

The electric clutch should provide years
of service. The clutch has a built-in brake
that stops the pulley within 5 seconds.
Eventually, the internal brake will wear
which may cause the mower blades to
not engage, or, to not stop as required.
Adjustments should be made by a Sears
or other qualified service center.
1. Make sure attachment clutch and igni­
tion switches are in “OFF" position.
Adjust the three nylon locknuts until
space between clutch plate and rotor
measures .012" at all three slot loca­
tions cut in the side of brake plate.
NOTE: After installing a new electric
clutch, run tractor at full throttle and
engage and disengage electric clutch 10
cycles to wear in clutch plate.

TO CHECK AND ADJUST BRAKE
Your tractor is equipped with an adjustable
brake system which is mounted on the
right side of the transaxle.
If tractor requires more than five (5) feet to
stop at highest speed in highest gear on a
level, dry concrete or paved surface, then
brake must be checked and adjusted.
TO CHECK BFIAKE
1. Park tractor on a level, dry concrete or
paved surface, depress clutch/brake
pedal all the way down and engage
parking brake.
2. Place gear shift lever in neutral (N)
position.
The rear wheels must lock and skid when
you try to manually push the tractor for­
ward. If the rear wheels rotate, the brake
needs to be adjusted or the pads need to
be replaced.
TO ADJUST BRAKE
1. Depress clutch/brake pedal all the way
down and engage parking brake.
2. Measure distance between brake oper­
ating arm and nut “A” on brake rod.
3. If distance is other than 1-3/4", loosen
jam nut and turn nut “A” until distance
becomes 1 -3/4". Retighten jam nut
against nut “A”.
Road test tractor for proper stopping
distance as stated above. Readjust
if necessary. If stopping distance is
still greater than five (5) feet in highest
gear, further maintenance is neces­
sary. Replace brake pads or contact a
Sears or other qualified service center.
