THROWING WHEEL REPLACEMENT
1. Turn the throwing wheels “OFF” and unplug the power cord. Remove 4 bolts
holding the top wheel guard to the bottom 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 10).
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.
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 without
wobble before turning the unit “ON”.
e. Be sure the top wheel guard is properly and securely reinstalled.
NOTE:
Check bolts for tightness once a season. Tighten bolts securely, but be sure not
to over-tighten.
