Maintenance
Disassembly
1. Loosen the set screw and remove the coupling half (item 2) from the top of the mixer shaft.
2. Gently hold the mixer tube (item 7) so as not to crush it, and use a 3/8” punch and hammer to drive the mixer
shaft up from the bottom until the bearing assembly (item 3) is exposed.
3. Use a 1/8” punch to remove the roll pin and slide the bearing assembly off the top of the shaft.
4. Remove the bottom bearing setscrew (item 13) and remove the bottom bearing (item 12).
5. Slide the shaft assembly down through the mixer tube and remove it out the bottom.

Inspection
1. Measure the inside diameter of the shaft hole on the bottom bearing (item 12) and the center bearing (item
10). If it is more than .425 it should be replaced.
2. Visually inspect the turbine assembly (item 11) for wear and replace if needed.

(item 4) area.
