bearing (4) straight off of seal plate (2). Inspect all parts for signs
of wear and replace as needed.
CAUTION: - Handle seal parts with extreme care.
DO NOT scratch or mar lapped surfaces.
F-3.2) Replacing Bearings:
When replacing bearings, be careful to not damage the rotor or
shaft threads. Press the old bearings off the shaft with an arbor
press or gear puller. Clean the shaft thoroughly. Apply adhesive
compound to shaft and press new bearing on, pushing only on
the inner race, until it seats against shoulder of shaft (see fig.8)
IMPORTANT: - All parts must be clean before
reassembly.
F-3.3) Reassembly:
Make sure shaft seal (3) is clean and in proper position as per
section F-4.2 before reassembling rotor and bearing. Slide
lower bearing and rotor shaft squarely into the seal plate (2)
until bearing seats on the bottom. Insert snap ring (5) into seal
plate with flat edge against outer race of bearing. Place motor
stator squarely onto seal plate and tighten motor screws. Install
square ring squarely (11) onto seal plate. With cord assembly
(8) properly assembled, slip cord through motor housing (see
Fig. 4). Connect motor wires to cord set as per figure 5 & 6.
Place motor housing squarely onto seal plate while pulling
excess cord through hole. Tighten socket head screws (13) into
motor housing. Tighten gland nut (8a) against washers (8b) and
grommet (8c). Refill with cooling oil as per paragraph F-1.3.
F-4) Shaft Seal Service
F-4.1) Dissassembly and Inspection:
Disassemble pump motor as per section F-3.1. Inspect seal for
signs of wear such as uneven wear pattern on the stationary
member or chips and scratches on either sealing face. Do not
interchange seal components. Replace entire seal if damage
occurs.
F-4.2) Replacing Shaft Seal (refer to fig. 6 & 7):
When replacing the shaft seal (3), remove used rotating
member (3c), spring (3b), and spring retainer (3a) from motor
shaft. Press used stationary member (3d) from the seal plate
(2). At reassembly, clean seal cavity thoroughly and apply a
light coat of oil. Lightly oil the rubber ring (
DO NOT use grease)
and press the stationary member firmly into the seal plate using
a seal pusher (See Parts List- Seal Tool Kit), nothing but pusher
to come in contact with seal face (see Fig. 7a).
