To Reassemble:
Be sure that recess for seal seat is free of all dirt and scale.
Apply a thin film of light oil to the recess of the motor
adapter and the neoprene bushing before installing the
new seal seat. This is a tight fit, but it must go in all the
way evenly or a leak will result. It can be pushed in with
the two thumbs. Do not mar lapped face of this seal. The
slightest scar or particle of dirt will cause a leak.
Assemble rotating member of seal on motor shaft.
Rotating seal face must fit snugly against lapped seal face
of stationary member in motor adapter. This is
accomplished by placing the rotating seal, sealing face
toward stationary seat, on the shaft. Use the impeller to
drive and seat the rotary seal.
Place gasket on motor adapter being careful the holes in
gasket line up with openings in the adapter. If gasket is
badly worn or has been damaged in any way, replace
with a new one.
While holding the shaft against rotating, as described in
A.O. Smith motors, page 3, screw impeller on shaft by
hand until tight against shoulder of motor shaft.
Replace guide vane, making sure that bore of guide vane
does not bind impeller hub, tightening screws alternately
and evenly. This can be checked by turning the motor
shaft. If binding occurs, loosen screws, re-adjust guide
vane until impeller hub turns freely, then tighten screws
as before.
Replace entire assembly in casing making sure gasket is
flat all the way around and has not been damaged. Also

LOCATING TROUBLE

LOCATING TROUBLE

IF YOUR UNIT FAILS TO FUNCTION PROPERLY

If your Goulds Pumps BF03S Water System fails to operate
properly after the foregoing instructions have been
followed, the trouble can usually be traced to certain
simple causes. Such as inadequate priming, air leaks in the
suction line, foreign matter in system, low voltage in power
line causing low motor speed, insufficient flow from well
or other source of supply, excessive suction lift, or a house
service line that is too small or too long causing excessive
friction loss. The following suggestions for locating
troubles should be followed in the order given, making sure
that each step does not remedy the trouble before trying
the next one.

IF PUMP RUNS BUT DOES NOT DELIVER WATER

NOTE: On long suction lines it may take considerable time
for the pump to exhaust all of the air in the
suction pipe and start to deliver water. When
starting the pump under these conditions, always
leave a faucet open for the air to escape. If there is
a foot valve on the end of the suction line, filling
the suction piping with water before starting will
shorten the time required for the pump to start
delivering water.
1. Examine pump by removing priming plug to see if if is
full of water. NOTE: Three quarts of water poured in
priming opening is sufficient to prime pump.
2. Check source of supply to see if there is an ample supply
of water available and that the end of suction pipe is
submerged in water but not buried in mud.
3. Check motor rotation. Make sure that motor runs in
direction indicated by arrow on pump casing cover.
