F-3.3) Checking Of End-Play:
Measure distance with micrometer from the top surface of the
motor cover to the end of the shaft. See Figure 3. Temporarily
set the partially assembled unit on the lower end of the shaft,
causing the bearings to slide up in the bearing retainer.
When the bearings bottom securely, again measure the
distance from the top surface of the motor cover to the end
of the shaft. This difference should be between .015 to .030
inches. If the end-play is within these tolerances, proceed
with reassembly. If the end-play is not within the above listed
tolerances, the motor upper end bell must be disassembled
and suffi cient .010 shims (9) must be added or removed as
required. Reassemble and recheck again for the required
listed end-play tolerance.
F-4) Shaft Seal and Diaphragm Service:
Important! - Handle seal parts with extreme care.
do not scratch or mar lapped surfaces.
F-4.1) Disassembly and Inspection:
Diaphragm -
To examine or replace the diaphragm (32) or
shaft seal (46), remove impeller (28) as outlined in paragraph
F-2.1. Drain oil from seal chamber as outlined in paragraph
F-1.3. Remove cap screws (8) and lifting strap (7). Set unit
upside down on blocks to avoid damaging cords. Remove
socket head cap screws (39) and lift seal plate (25) vertically,
being cautious to avoid seal damage, together with
diaphragm (32), clamp (43) and outboard stationary member
(46A) of shaft seal (46), from bearing bracket (21). Examine
diaphragm (32), if it is ruptured, cracked or damaged, replace
by removing screws (44) and diaphragm clamp (43), Also,
clean out vent holes in seal plate (25). Check moisture sensor
probes (18) (if equipped) for damage. Replace by
disconnecting wires (16) by removing screws (14) and
lockwashers (15). Then remove probe (18) from bearing
bracket (21).
Seal -
To expose shaft seal (46) for examination, complete
above procedure and slide off outboard rotating member
(46B), See Figure 4. Remove inboard rotating member (46),
from shaft. Examine all seal parts and especially contact
faces. Inspect seal for signs of wear such as uneven wear
pattern on stationary members, chips and scratches on either
seal face.
DO NOT
interchange seal components, replace the
entire shaft seal (46).
