8.  Place the 1st stage impeller (item 2) into position.  Align the flats on the drive shaft with the flats in the impeller shaft. These two 

parts fit snugly and some pressure may be required to put the impeller into position. See figures 62 & 63.

9.  Install the impeller housing (item 1). Align the alignment boss in the housing with the notch in the inner volute assembly (item 6). To 

get the housing to seat properly in may be necessary to move the housing back & forth. If housing will not seat remove the housing 

& align the notch. Note: due to magnetic attraction the pump assembly may want to pop up. Simply push it back down. Make sure 

the discharge is in the correct orientation in relation to pump foot. Rotate the housing until the discharge is in the correct position.  

Holding the impeller housing with one hand, install and finger-tighten two bolts, lock washers and flat washers (items 19, 20 & 21) in 

opposite locations. See figures 64 thru 65.

10.  Install the remaining bolts, lock washers and flat washers finger tight.

11.  Tighten all the bolts evenly using a star pattern. Tighten to 

20 foot-lbs (27 N-m)

.

12.  Reinstall the pump on the motor/drive magnet following instructions found in “Assembly, Pumps Without Motors,” steps 7-10.
