Installation and Service
Before any service work is
done, disconnect and lock
IMPORTANT! - All parts must be clean before

care. DO NOT damage lapped surfaces.
REASSEMBLY
Bearing
Be careful not to damage the rotor shaft when replacing
bearing. Using an arbor press, hold the rotor and press
the upper bearing on the rotor shaft, applying force to
the inner race of the bearing only. In the same manner
replace lower bearing onto rotor shaft.
Inner Seal
Clean and oil seal cavity in seal housing. Lightly oil (Do
not use grease) outer surface of stationary member. Press
seal's stationary member firmly into seal housing, using
a seal tool or pipe. Nothing should come in contact with
the seal face except the seal tool. Be sure the stationary
is in straight. Place seal's retaining ring and spring over
shaft until seated. Slide a bullet tool over rotor shaft
threads.
Lightly oil (Do not use grease) shaft, bullet, and inner
surface of bellows on rotating member, slide rotat-
ing member over bullet and onto shaft until it engages
spring. Make sure spring is seated in retaining ring and
spring is lined up on rotating member and not cocked
or resting on bellows tail. Compress spring and install
retaining ring.
Seal Housing
Lubricate and set o-ring in bottom groove of seal plate.
Place seal plate over shaft and onto seal housing, being
sure o-ring is not twisted and in the groove. Place four
capscrews through holes in seal housing and into seal
plate and torque to 6.5 ft/lbs.
Outer Seal
Clean and oil stationary seal cavity in seal plate. Slide
seal guide tool over motor shaft. Lightly oil (Do not use
grease) outer surface of seal's stationary member.
Press stationary firmly into seal plate using a seal pusher
tool. Be sure the stationary member is in straight. Noth-
ing but the seal tool is to come in contact with seal face.
IMPORTANT ! Do not hammer on the seal
pusher. It will damage the seal face.
With lapped surface of rotating member facing inward
toward stationary, slide rotating member and onto shaft,
until lapped faces of stationary and rotating seal are to-
gether. Place spring over shaft and rotating member. Be
sure it is seated on the retainer and not cocked or resting
on bellows tail.
Impeller
Install impeller (7) on the motor shaft by installing key
on motor shaft, slide the impeller on the motor shaft
aligning the key. Do Not store pump without impeller in
