F-2.2) Reassembly:
To install impeller (33), clean the threads with thread
locking compound cleaner. Apply removable Loctite® 603
or equivalent to shaft threads. Screw impeller onto the shaft
hand tight while using a screwdriver in the slot at the end of
the shaft to hold it stationary. Apply thread locking compound
(60) to shaft threads. Then install jam nut (66) and torque to
40 ft. lbs. It is important that the spring of the lower shaft seal
(28) seats in the hub of the impeller (33). Rotate impeller to
check for binding. Position gasket (36) on volute fl ange and
position impeller and motor housing on volute (1). Position
lockwasher (12) on cap screw (26) and screw into volute (1).
Torque to 100 in-lbs. Check for free rotation of motor and
impeller.
F-3) Shaft Seal Service:
IMPORTANT!
Handle Seal Parts With Extreme Care.
Do Not Scratch Or Mar Lapped Surfaces.
F-3.1) Disassembly and Inspection:
To expose shaft seal (28) for examination, disassemble
volute and impeller as outlined in paragraph F-2.1. If further
repair is required, remove retaining ring (28d), spring (28c)
and rotating member (28b) from shaft (see Figures 6 & 7).
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 (28). If replacing seal, remove stationary (28a) by
prying out with fl at screwdriver.
F-3.2) Reassembly:
IMPORTANT!
Do Not Hammer On The Seal
Pusher-it Will Damage The Seal Face.
Clean and oil seal cavity in seal plate (5). 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).
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) 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.
Position unit upright, using blocks to avoid resting unit on
shaft. Unscrew cable hex bolts (11) and remove compression
fl ange (16a) and power cord (16). Remove snap ring (19) with
a fl at head screwdriver. Pull the terminal block (21) out of the
housing (6) using a T-bolt or pair of pliers and a .25-20 screw
in the threads of the terminal block (21).
