Bearing - When replacing bearing, be careful not to damage
the rotor or shaft threads. Clean the shaft thoroughly. Slide
conduit bushing (16) and washers (25), (33) over motor shaft.
Apply adhesive compound to the shaft and press bearing
(21) on the motor shaft, position squarely onto shaft applying
force to the inner race of the bearing only, until bearing seats
against shoulder of the shaft.
Seal - Clean and oil seal cavity in lower end bell (10). Press
stationary member (1a) fi rmly into lower end bell (10), using a
seal pusher (see parts list - seal tool kit), nothing but the seal
pusher is to come in contact with seal face (see Figure 4).
Make sure the stationary member is in straight.
IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.

seal faces clean during assembly. Dirt particles
lodged between these faces will cause the seal to
leak.
Motor - Slide motor rotor with conduit bushing (16), washers
(25), (33) bearing (21) and seal parts (1b, c, d) into lower
end bell (10) until bearing (21) seats in lower end bell (10).
Center washers (25), (33) on bearing (21) and tighten conduit
bushing (16) on lower end bell (10).
Lower motor stator over rotor until seated in lower end bell
(10), while aligning holes for motor bolts. Insert motor bolts
and torque to 17 inch pounds. If pump is a single phase unit
place bracket (17) on one of the motor bolts. Insert capacitor
(18) in bracket (17), attach motor leads with fl ag terminals to
capacitor and place terminal boot (15) over terminals.
Set motor housing (11) next to motor (14) and lower end bell
(10) assembly. Make wire connections per paragraph F-3.3.
Set square ring (23) in groove on lower end bell (10) and
lower motor housing (11) down onto lower end bell (10) while
aligning holes. Place socket head cap screws (36) through
lower end bell (10) into motor housing (11) and torque to 60
