F-3.2) Reassembly: <br />Inner Seal (DS Units Only)- Clean and oil seal cavities in <br />seal plates (5. 29). Lightly oil (DO NOT use grease) outer <br />surface of stationary member (28a). Press stationery member <br />(28a) firmly into inner seat plate (5), using a seal pusher (see <br />parts list - seal too( kit). Nothing but the seal pusher is to <br />come in contact with seal face (see Fig 9). <br />IMPORTANT! - DO NOT hammer on the seal <br />pusher- it will damage the sea! face. <br />Make sure the stationary member is in straight. Slide a bullet <br />(see parts list - seal tool kit) over motor shaft. Lightly oil (DO <br />NOT use grease) shaft, bullet and inner surface of bellows <br />on rotating member (28b) see Figure 10. With lapped surface <br />of rotating member (28b) facing inward toward stationary <br />member, slide rotating member over bullet and onto shaft, <br />using seal pusher, until lapped faces of (28a) and (28b) are <br />together (see Figure 9). <br />It is extremely important to keep seal faces clean during <br />assembly. Dirt particles lodged between these faces will <br />cause the seal to leak. Place spring (28c) over shaft and in <br />place on rotating member (28b), making sure it is seated <br />on retainer and not cocked or resting on bellows tail. Slide <br />retaining ring (28d) over shaft and let rest on spring (28c). <br />Replace snap ring (32) in groove of shaft. Set square -ring <br />(27) in groove on outer seal plate (29) and place outer seal <br />plate (29) onto inner seal plate (5). Replace socket head cap <br />screws (64) and torque to 60 in -lbs. <br />Outer Seal (All Units)- Press stationary member (28a) firmly <br />into outer seal plate (5, or 29 on DS Units) as described <br />above. Slide rotating member (28b) onto stationary member <br />using seal pusher as described above. Place spring (28c) and <br />retaining ring (28d) onto rotating member (28b). Assemble <br />impeller and volute as outlined in paragraph F-2.2. Replace <br />oil as outlined in paragraph F-1.4. <br />F-4) Motor and Bearing Service <br />F-4.1) Disassembly and Inspection: <br />To examine or replace the motor (7), capacitor (9, single phase <br />units), controls (55, 56, optional), and bearing (25), drain oil <br />from motor as outlined in paragraph F-1.1. Disassemble volute <br />and impeller as outlined in paragraph F-2.1 and disassemble <br />shaft seal as outlined in paragraph F-3.1. <br />Stationary Member <br />(28A) Polished Face Out <br />FIGURE 11 <br />Seal Pusher <br />Seal Plate (5) for L series <br />FIGURE 9 and (29) for DS series <br />Motor & Seal Plate <br />Seal Pusher <br />l <br />Bullet Rotating Member <br />(28B) <br />FtGURc 10 <br />13 <br />4-i <br />
