Belt Removal; Belt Installation - Craftsman 917.28645 Operator's Manual

TO ADJUST ATTACHMENT CLUTCH
The electric clutch should provide years of
service. The clutch has a built-in brake that
stops the pulley within 5 seconds. Eventu-
ally, 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 ser-
vice center.
1. Make sure attachment clutch and ignition
switches are in "OFF" position.
2. Adjust the three nylon Iocknuts until space
between clutch plate and rotor measures
.012" at all three slot locations 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 BRAKE

stop at highest speed in highest gear on a
level, dry concrete or paved surface, then
brake must be serviced.
You may also check brake by:
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) posi-
tion.
The rear wheels must lock and skid when
you try to manually push the tractor forward.
If the rear wheels rotate, then the brake
needs to be serviced. Contact a Sears or
other qualified service center.
FRONT WHEEL TOE-IN/CAMBER
Your new tractor front wheel toe-in and
camber is set at the factory and is normal.
The front wheel toe-in and camber are not
adjustable. If damage has occurred to
affect the factory set front wheel toe-in or
