Install the spacer, washer, and rotor pulley on the
end cap shaft. Tighten the rotor pulley by turning
nut counterclockwise finger tight (Left hand
thread) (Figure 81.).
Note: The rotation of the rotor pulley during
operation will tighten the pulley to the correct
torque.
8. Assemble the rotor halves and paddles. Refer to
"End Cap/Shaft And Bearing Replacement For

designed with the four self-tapping rotor locating
screws. After the rotor halves are secured to the
new end cap, holes must be drilled. Using holes in
the rotor halves as guides, drill (2) 7/32” holes in
end cap (Figure 82).
