Install spacer ensuring pilot fits into the adjusting nut assembly. 6. Determine the distance impeller must be raised as specified by the pump vendor. 7. Turn adjusting nut until distance 'A' is equal to distance from Step 6 (Figure 1). Turn adjusting nut downward onto shaft to align bolt holes with pump hub. 8.
