10.1 BLAST WHEEL REPLACEMENT
WARNING: The 1-8DEZ must be placed in Maintenance Mode
(see section 2.3) prior to attempting to inspect, change, or
adjust the blast wheel.
See Section 4 and drawing 421-0001 for parts identification
1. Place 1-8DEZ into maintenance mode.
2. Loosen the two control cage clamps that secure the feed spout and control
cage.
3. Remove the feed spout and the control cage.
4. Outline the area around the control cage bracket 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.
5. Remove the arbor nut and remove the blast wheel.
6. Check the wheel drive hub for wear and replace if necessary.
7. Install new blast wheel using the arbor nut that is included in the wheel kit.
Check the two drive pins on the drive hub for wear and replace if necessary.
Be sure that the new blast wheel is seated properly on the wheel hub before
tightening the socket head cap screw.
8. Reinstall the control cage bracket to the blast housing using the outline made
before removing the assembly.
9. 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.
10. Reinstall the feed spout and band seal that connects the feed spout and
abrasive valve.
