b. Cleaning, Inspection and Repair.
Drycleaning solvent, P-D680, used to clean parts is potentially dangerous
to personnel and property. Avoid repeated and prolonged skin contact. Do
not use near open flame or excesive heat. Flash point of solvent is 100
degrees F - 138 degrees F (38 degrees C - 59 degrees C).
(1) Clean parts with drycleaning solvent (Item 1, App. E).
(2) Dry parts thoroughly.
(3) Inspect the impeller, seal, coupling, and other components for damage or defects.
(4) Replace worn or defective parts.
(5) 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
c. Assembly and Installation (figure 5-1).
(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
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 engine/motor with four screws (14) and new compression
inserts (15). Torque evenly to 32 ft. Ibs. (36.90 cmkg). Lubricate rubber seal (item g, App E).
(4) Install adapter shaft (16) onto armature/crank shaft. Seat stationary seal into Rubber Seal and
slide onto adapter shaft and pump cavity. Install Rotating Seal over adapter shaft (see figure 5-2).
When the Seal, Assembly, Shaft is ordered, an alternate configu-
ration of the Rotating Seal may be received.
The uncaged spring
and carbon seal is fit and functionally the same as the caged Ro-
tating Seal, and is installed in the same way. An illustration
of the Alternate Rotating Seal is included in Figure 5-2.
