MAINTENANCE AND REPAIR
7. If desired to separate the any of the compo
nents removed in Step 6, lubricate the cables to
ease removal. Remove the rubber seals (235),
and loosen the screws (239) securing the cable
clamps (238).
NOTE
In the stator/motor housing (246), the stator (301) is
a hot shrink fit in the motor housing (302). No in
structions are given in this manual for separating
the stator/motor housing, or thermal protectors
(307). It is strongly recommended that the stator/
motor housing be returned to the factory or an
authorized Gorman‐Rupp repair facility if any of
these components require service.
INSPECTION AND CLEANING
Carefully inspect all O‐ring seating areas to deter
mine if they formed a proper seal. If sealing was
faulty, determine the cause before reassembling
the pump. After inspection, remove and discard all
O‐rings.
Most cleaning solvents are toxic and
flammable. Use them only in a well‐ven
tilated area free from flame, sparks, and
excessive heat. Read and follow all pre
cautions printed on solvent containers.
Bearings
1. It is recommended that bearings be cleaned in
place on the shaft.
2. Clean bearings thoroughly in
fresh
cleaning
solvent; dry with filtered compressed air.
3. Pack the bearings with “Shell Darina Grease
R2” or equivalent, and coat external surfaces
with light oil to ease reassembly.
4. Cover the bearings with clean cloth to keep ex
ternal surfaces free of all dirt and foreign mate
rial;
failure to do so could damage the bear
ings or their mating surfaces
.
Other Reusable Parts (Except Seal Assemblies)
1. Thoroughly clean all reusable parts.
2. Inspect all mating surfaces and the rotor/shaft
assembly for nicks or burrs, and restore to origi
nal contours with a honing stone or fine file.
3. If the surface cannot be restored, replace the
part.
