NOTE: There are two types of couplers used on Series 60
ffi
>
pumps. The type of coupler is dependent on the size of the
pump. All AA size pumps use B&G spring coupler assem­
blies. All A size pumps with FRACTIONAL HP (¼, 1/2, ¾)
use B&G spring couplers whereas A size pumps with HP
GREATER THAN 1 (1-1/2, 2) use Woods sleeve couplers.
The F size pumps also use the Woods sleeve couplers.
Lovejoy jaw type couplers are compatible with the Woods
sleeve couplers and can therefore be used interchangeably
wherever the Woods is used.
For motors with Woods or Lovejoy type couplers, skip step
3 and continue with step 4. Only pumps with spring couplers
require step 3 operations for disassembly.
3. Release the coupler from the pump shaft by loosening the
set screw with an Allen wrench. The set screw rests in a
blind hole along the shaft; the set screw must therefore be
backed of at least 1/e'' before attempting to remove the coupler.
If stuck, a screwdriver may be used to gently pry the coupler
from the shaft (before prying, be certain that the set screw
has cleared the depth of the blind hole - usually three full
turns of the wrench will clear the hole).
4. Separate the motor from the bearing assembly by removing
the four cap screws from the cover plate.
