Bearing Bracket and Cutter Disc Removal.

2. Match mark the bearing bracket support arms with the water tank for reassembly reference.
3. Remove the splash shield and ice deflector plate from the ice discharge opening.
4. Support the bearing bracket to keep it from falling in the tank. Loosen and remove the four cap
screws and lock washers from the ends of the bearing bracket support arms.

The cutter shaft and bearings are sealed in the bearing bracket assembly. The cavity between the
bearings has been filled with a food-grade grease to prevent the presence of moisture and prolong the
life of the unit. If there is any vertical or side movement of the shaft or if the bearings feel rough or
tight when turning the shaft, the assembly should be dismantled and rebuilt. Refer to the cutter tank
assembly drawing, Figure 9-5B, for parts location and identification.

from the bottom up.

damage.
