E-3.2) Reassembly:
Outer Seal -

 Clean and oil seal cavities in seal plate 

(10). Lightly oil 

(DO NOT use grease)

 outer surface of 

stationary member (12a). Press stationary member (12a) 
fi rmly into seal plate (10), using a seal pusher (see parts 
list- seal tool kit). Nothing but the seal pusher is to come 
in contact with seal face (see Fig. 6). 

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 (12b) (see Fig. 7). With 
lapped surface of rotating member (12b) facing inward 
toward stationary member (12a), slide rotating member 
(12b) over bullet and onto shaft, using seal pusher, until 
lapped faces of (12a) and (12b) are together (see Fig. 5).

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 (12c) over shaft and in place on rotating 
member (12b), making sure it is seated on retainer and 
not cocked or resting on bellows tail. Slide retaining ring 
(12d) over shaft and let rest on spring (12c). Assemble 
impeller, cutter and volute as outlined in paragraph E-2.2. 
Replace oil as outlined in paragraph E-1.3.
