Blast Wheel Replacement
9.1 Blast Wheel Replacement
CAUTION: ALL ELECTRIC POWER MUST BE DISCONNECTED AND ALL
ROTATING PARTS MUST BE COMPLETELY STOPPED BEFORE ATTEMPTING
THIS PROCEDURE.
1. Loosen the two control cage clamps that secure the feed spout and control cage.
2. Remove the feed spout and the control cage.
3. Outline the area around the control cage mounting assembly with a marking pen or
pencil. This will allow for easier alignment when reinstalling this part later during this
procedure. Remove the four mounting nuts, flat washers and lock washers that
secure the control cage mounting assembly to the blast housing. Do not loosen any
other screws on the control cage mounting assembly since they are used to set the
gap between the blast wheel and the control cage. Remove the control cage
mounting assembly.
4. Remove the socket head cap screw and lock washers from the blast wheel and
remove the blast wheel.
5. Check the wheel hub for wear and replace if necessary.
6. Install new blast wheel using the new socket head cap screw and lock washers that
are included in the wheel kit. Be sure that the new blast wheel is seated properly on
the wheel hub before tightening the socket head cap screw.
7. Reinstall the control cage mounting assembly to the blast housing using the outline
made before removing the assembly.
8. Install the new control cage that was included with the wheel kit. Rotate the wheel
by hand to be sure the control cage and the wheel do not make contact. The initial
window setting for the control cage should be between 9:30 and 11:30.
9. Reinstall the feed spout.
10. Energize the blast motor momentarily to check for good balance and proper
clearance before shotblasting.
