DO NOT
interchange seal components, replace the entire
shaft seal (31). If replacing seal, remove stationary (31a) by
prying out with fl at screw driver.
F-4.2) Reassembly:
Seal - Clean and oil seal cavities in seal plate (1). Lightly oil
(DO NOT use grease) outer surface of stationary member
(31a). Press stationary member (31a) fi rmly into seal plate
(1), 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 7).
Important ! - DO NOT Hammer On The Seal
Pusher- It Will Damage The Seal Face.
Make sure the stationary member is in straight. Slide a bullet
(see parts list-seal tool kit) over motor shaft. Lightly oil (DO
NOT use grease) shaft, bullet and inner surface of bellows on
rotating member (31b) (see Figure 8). With polished surface
of rotating member (31b) facing inward toward stationary
member (31a), slide rotating member (31b) over bullet and
onto shaft, using seal pusher, until polished faces of (31a)
and (31b) are together (see Figure 9).
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 (31c) over shaft and in place on rotating member
(31b), making sure it is seated on retainer and not cocked or
resting on bellows tail. Slide retaining ring (31d) over shaft
and let rest on spring (31c). Assemble impeller and volute
as outlined in paragraph F-2.2. Replace oil as outlined in
paragraph F-1.4.
