c. Cleaning, Inspection and Repair.
Drycleaning solvent, P-D-680, used to clean parts is potentially
dangerous to personnel and property. Avoid repeated and pro-
longed skin contact. Do not use near open frame or excessive
heat. Flash point of solvent is 100 degrees F-138 degrees F
(38 degrees C59 degrees C).
Clean parts with drycleaning solvent (Appendix F, Item 1).
Dry parts thoroughly.
Inspect the impeller, seal, coupling, and other components for damage or defects.
Replace worn or defective parts.
Replace all seals, gaskets, compression inserts, and O-Rings.
Items (5, 7, 12, 13, 15) MUST be replaced each time the pump
is removed and disassembled.
d. Reassembly (Figure 5-10.1).
(1) Attach studs (20 and 27) to pump case.
(2) install large weight (21), gasket (22), small weight (23), screw (24), suction flange (25) and nuts (26).
Item (15) is a compression insert that will not reseal after once
compressed. Replace with new compression inserts.
(3) Install key (17) and attach pump (19) to motor with four screws (14) and new compression inserts (15). Tor-
que evenly to 32 ft. lbs. (36.90 cm-kg).
(4) Install adapter shaft(16) onto armature shaft. Seat stationary seal into Rubber Seal and slide onto adapter
shaft and pump cavity. Install Rotating Seal over adapter shaft (see Figure 5-10.1).
When the Seal, Assembly, Shaft is ordered, an alternate con-
figuration of the Rotating Seal may be received. The uncaged
spring and carbon seal is fit and functionally the same as the
caged Rotating Seal, and is installed in the same way. An il-
lustration of the Alternate Rotating Seal is included in Figure
