F-2.1) Disassembly and Inspection:
To expose outer shaft seal (13) for examination, remove
Impeller and Volute per Section F-1.1. Set motor assembly
(2) in the up position to prevent loss of oil. Remove snap
ring from motor shaft, then retaining ring (13D), spring (13C)
and rotating member (13B) from shaft, See Fig. 4. 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
(13). If replacing seal, remove stationary (13A) from mounting
plate by prying out with fl at screw driver.
F-2.2) Reassembly:
Lightly oil (DO NOT use grease) outer surface of stationary
member (13A). Press stationary member (13A) fi rmly into
mounting plate using a seal pusher, nothing but the seal
pusher is to come in contact with seal face (see Fig. 5).
IMPORTANT ! - DO NOT hammer on the seal
pusher- it will damage the seal face.
Make sure the stationary member is in straight and that
the rubber ring is not out of it’s groove. Lightly oil (DO NOT
use grease) shaft and inner surface of bellows on rotating
member (13B) see Fig. 6. With lapped surface of rotating
member (13B) facing inward toward stationary member
(13A), slide rotating member (13B) onto shaft using a seal
pusher, until lapped faces of (13A) and (13B) are together.
(see Fig. 4).
IMPORTANT! - It is extremely important to keep
seal faces clean during assembly. Dirt particles
lodged between these faces will cause the seal to
leak.
Place spring (13C) over shaft and in place on rotating
member (13B), making sure it is seated on retainer and not
cocked or resting on bellows tail. Slide retaining ring (13B)
over shaft and let rest on spring (13C). Assemble impeller
and volute as outlined in paragraph F-1.2.
