COMPONENT REPLACEMENT
THROWING WHEEL REPLACEMENT
1. Turn the throwing wheels “OFF” and unplug the power cord. Remove four bolts
holding the wheel guard to the motor-side wheel guard.
2. Hold the wheel so that it cannot move. Turn the keyway retaining bolt counter-clockwise
using a box end wrench (See Figure 9).
SUGGESTION: If the bolt is too tight, give the opposite end of the wrench a series of
light taps with a hammer making sure the wrench remains on the bolt.
3. Remove the bolt and washers.
4. Work the wheel off of the motor shaft. Be sure to catch the key as it is freed from
the keyway.
5. Ball throwing wheels are machine balanced. Small holes in the side of the wheel are
applied at the factory and are normal. A slight wobble is also normal.
Reassemble in reverse order.
a. Install wheel to motor shaft with key slots aligned.
b. Be sure the key is in place, and inserted so that it is flush with the boss at the
wheel center.
c. Be sure the washer and lock washer are installed in the right order, and that the
keyway retaining bolt is tightened.
d. Test the wheel by spinning it by hand and making sure that it spins freely before
turning the unit “ON”.
e. Be sure the wheel guard is properly and securely reinstalled.
NOTE: Check bolts for tightness once a season. Tighten bolts securely, but do
not over-tighten.
MOTOR REPLACEMENT
1. Turn the on/off switch “OFF” and unplug the power cord.
2. Remove the throwing wheel (see above) and two wheel guards.
3. Remove four screws holding controller into main electrical box. Note the position of
the motor wires on the controller, then disconnect the wires. See Page 14.
4. Note the routing of the motor wires. Loosen any wire clamps.
5. Remove bolts holding the motor to the main frame.
Reassemble in reverse order.
