3. Direction of blower rotation
Proper blower rotation is extremely important. Blower
rotation is determined by viewing the motor and wheel
from the REAR of the motor (or from the open end of
the oven). See Figures 37-39.

4. Removing the blower wheels
To change a motor or blower wheel, the wheel must
first be removed from inside the oven as follows:
•
Remove the end plugs and conveyor assembly.
• From inside the oven cavity, reach into the blower
recess and remove the inlet rings. See Figure 40.
• Loosen the set screw on the blower wheel hub and
remove the blower wheel. A special wheel puller
tool (P/N 42400-0101) is available for this purpose.
See Figure 41.
IMPORTANT: Before installing the new wheel,
apply an anti-seize lubricant (Middleby P/N 17110-
0017) to the motor shaft and the inside of the blower
wheel hub.
