6b.Hold stator (44) with pipe or strap wrench and turn
drive shaft (4) clockwise to force stator (44) off rotor (37).
7. Check rotor (37) and stator (44) for wear. See Rotor
(4-30) and Stator (4-31) for instructions.
4-13. Rotor Removal
1. Complete sections 4-9 and 4-11.
2. Remove stator adaptor (21) and O-ring (20) from suc-
tion housing (19).
3. Remove hopper or suction piping from suction
housing (19).
4. Remove socket head pipe plug (P) and set screw (Q)
from gear joint shell (36).
5. While supporting weight of rotor, remove six socket
head screws (N) from head ring (39), and slide head ring
(39) and O-ring (38) off rotor. Separate rotor from gear joint.
Note: If rotor-end gear joint is not accessible, disassemble
drive-end gear joint by following the procedure in sec-
tion 4-14, steps 1-3. Then remove both the conveyor
assembly and rotor from suction housing as a single
unit.
4-14. Gear Joints and Conveyor Assembly Removal
1. Complete sections 4-9 thru 4-12.
2. Remove pipe plug (P) from gear joint shell (33).
Remove six socket head screws (N) from gear joint retainer
(34), and slide retainer and O-ring (24) toward conveyor
flight.
3. Pull conveyor assembly (35) from drive-end gear joint
until it is separated from gear joint shell (33) and completely
separated from suction housing (19).
4. Remove lock nut (28) from drive-end of conveyor as-
sembly, and slide gear ball (29), secondary thrust plate (30),
seal support (31), gear joint seal (32), and gear joint retainer
(34) from conveyor assembly.
5. Remove two keys (26), ring gear (27), and primary
thrust plate (25) from gear joint shell (33).
6. The other gear joint is disassembled in a similar man-
ner by first removing primary thrust plate (25) from rotor
head. Remove two keys (26) from gear joint shell.
7. Slide gear joint shell (36) toward flight on conveyor
assembly. Remove lock nut (28) from end of conveyor
assembly (35). Remove ring gear (27), gear ball (29),
secondary thrust plate (30), seal support (31), and gear
joint seal (32). Then slide gear joint shell (36) from conveyor
assembly.
Note: It is recommended that each time a gear joint is dis-
assembled, the O-rings and grease seal should be
replaced.
4-15. Drive Shaft and Bearings Removal
1. Complete sections 4-9 thru 4-13.
2. Remove drive coupling or V-belts and pulleys
from drive shaft (4).
3. Remove four socket head screws (O) from shaft
adapter (23), and remove adapter and gear joint shell (33)
from end of drive shaft (4).
4. Remove six hex head screws (A) from bearing cover
plate (2). Slide bearing cover plate (2) along with radial
grease seal (1) and O-ring (3) off drive shaft.
5. Drive shaft (4) and bearings can now be pulled out of
bearing housing (14), taking steps to support the weight of
the assembly as the bearings clear the housing. Remove
grease seal (9) from bearing housing (14).
CAUTION: The bearings are pressed on the shaft during
assembly. Care must be taken during
disassembly to avoid damaging the
bearings or shaft.
6. Remove bearing lock screw (7) from bearing nut (8).
Using suitable spanner wrench or soft punch and hammer,
thread lock nut off drive shaft.
7. Remove both halves of bearing spacer (6) from shaft,
and using suitable bearing press and adaptors, press bear-
ings off shaft.

1. Shut off pump.
2. Turn off flush water to packing or mechanical seal,
if used.
3. Disconnect power source.
4. Drain any fluid in pump.
4-18. Chain Replacement
1. Complete section 4-17, steps 1-3.
2. Remove oiler (1), oiler nozzle (1A), and guard (12).
3. Loosen idler arm adjusting screw (F) and remove
