FIGURE 8

Inner  Seal  (DS  Units  Only)-

  To  expose  inner  shaft  seal 

(28)  for  examination,  remove  outer  seal  as  outlined  above.  
Remove socket head cap screws (64). Lift outer seal plate (29) 
and square-ring (27) from inner seal plate (5), See Figures 6 & 
7. If further repair is required, remove snap ring (32), retaining 
ring (28d), spring (28c) and rotating member (28b) from shaft. 
Examine as outlined in outer seal paragraph. If replacing seal, 

remove stationary (28a) by prying out with fl at screwdriver.

F-3.2) Reassembly:
Inner Seal (DS Units Only)-

 Clean and oil seal cavities in seal 

plates (5, 29). Lightly oil (

DO NOT

 use grease) outer surface 

of  stationary  member  (28a).  Press  stationary  member  (28a) 
fi rmly into inner seal plate (5), 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 8).

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 (28b), see Figure 9. With lapped surface of rotating 
member (28b) facing inward toward stationary member, slide 
rotating member over bullet and onto shaft, using seal pusher, 
until lapped faces of (28a) and (28b) are together (see Figure 8).

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 (28c) over shaft and in place on 
rotating member (28b), making sure it is seated on retainer and 
not cocked or resting on bellows tail. Slide retaining ring (28d) 
over shaft and let rest on spring (28c). Replace snap ring (32) 
in groove of shaft. Set square-ring (27) in groove on outer seal 
plate (29) and place outer seal plate (29) onto inner seal plate 
(5). Replace socket head cap screws (64) and torque to 60 in-lbs.

Outer Seal (All Units) -

 Press stationary member (28a) fi rmly 

into  outer  seal  plate  (5,  or  29  on  DS  Units)  as  described 
above.  Slide  rotating  member  (28b)  onto  stationary  member 
using seal pusher as described above. Place spring (28c) and 
retaining  ring  (28d)  onto  rotating  member  (28b).  Assemble 
impeller and volute as outlined in paragraph F-2.2. Replace oil 
as outlined in paragraph F-1.4.

F-4) Motor and Bearing Service:
F-4.1) Disassembly and Inspection:

To  examine  or  replace  the  motor  (7),  capacitor  (9,  single 
phase  units),  controls  (56,  optional),  and  bearing  (25),  drain 
oil  from  motor  as  outlined  in  paragraph  F-1.1.  Disassemble 
volute  and  impeller  as  outlined  in  paragraph  F-2.1  and 
disassemble  shaft  seal  as  outlined  in  paragraph  F-3.1.
