A.
Motor \ Drive System
All motor \ drive components are easily removable and accessible by removing the motor from the motor
support platform.
1.
Removing Motor and Coupler
a.
Remove motor shroud.
b.
Remove hex head motor mounting bolts.
c.
Loosen the allen head set screw on the two-piece solid drive coupling.
d.
Remove motor away from drum.
e.
Remove coupler from shaft.
2.
Steel and Fiber Gears: Inspection and Replacement
The machine is designed so that teeth will shear off of the fiber gear in order to prevent the
motor from burning out due to sudden blockages. It is recommended to keep a spare fiber gear
in stock for immediate emergency service.
a.
Disconnect two-piece coupling from motor shaft.
b.
Remove allen set screws and face plate from motor.
c.
Visually inspect motor housing for damage to steel or fiber gears. Gears with any visible
damage (such as broken or missing teeth) must be replaced.
d.
Remove and replace faulty gear or gears.
e.
Lightly grease gears with lithium grease.
f.
Reassemble and remount coupling and motor.
3.
Drum Alignment
a.
Loosen but
DON’T REMOVE
the four bearing mounting bolts and motor mounting bolts.
b.
Place golf balls in the slots between the ball guides in the front of the drum. Rotate drum
toward you, about 1⁄4 of the way. Place golf balls in the slots in back of drum. Rotate the
drum away from you so that the balls are between the inner and outer drums.
c.
Leave the balls in place and tighten the bearings and motor mounting bolts. The drum is
now horizontally aligned. Make sure coupler set is level after tightening bolts.
d.
Gently rotate the top of the drum toward the front of the machine. The drum should turn
smoothly and evenly as balls travel between the lower guides and appear behind the drum.
e.
If the balls bind or jam, or if the drum turns with uneven resistance, there are two
probable causes:
1)
Foreign matter caught between the guides.
Remove the drum. Rinse the lower drum with water. This will eliminate any
small debris or foreign bodies lodged in the tracks.
2)
Vertical drum misalignment.
Shim under the pillow block bearings with 1/16” washers or sheet metal. Apply
one layer of shim at a time, rechecking the drum alignment after each layer, until
the drum turns freely. Excessive shim will interfere with proper ball
clearance on top of the drum.
NOTE
Resistance in drum rotation can also be a result of binding in pillow block bearings. Check by removing motor from
the machine and turning drum by hand without balls in the slots. Difficult rotation means bearings are binding and
must be replaced.
