The following is the
how-to on replacing either the pump or motor. Follow
Directions either way. |
|
 |
You will see 4 long bolts go
through the motor. If you are replacing the motor, the new
motor will have nuts on the opposite end shown in this
picture. If you are replacing the pump bracket, simply
loosen the bolts. Do NOT remove for they also hold the motor
parts together. Your old pump will be directional for the
discharge. Note on the pump bracket, you will see several
aligning guides to help you put the new pump face in the
proper alignment. Otherwise you might have to turn the pump
when you realize you aligned the pump wrong. You can do that
at any time by loosening the bolts to slightly pull out of
the pump and turn the pump to its proper alignment. |

Note the seals. 1/2 of the seal
sits in the cup on the bracket. The rubber is between the
cup and ceramic disk. Also note the other half of the seal
on the impellor's stem. THAT seal has the flat surface of
the seal against the back of the impellor and the plastic
side facing the other half of the seal. When you bring the
impellor and bracket together, the spring will push the
ceramic disk and plastic together and seal the pump. You
MUST do it this way. |
|
 |
While holding the impellor,
screw the motor shaft clockwise. Make sure you align the
impellor correctly on the motor shaft. Tighten to snug.
Also, if reusing an older motor, you MUST remove all rust.
If you don't, the larger diameter of the motor shaft will
likely split are ruin the new impellor. |

 |
The "o-ring" on the JPS pump is
actually square as you can see. Make sure the ring sits flat
on the oring seat and place the front or volute of the pump
over it. |
|
 |
Tighten the screws evenly using
a criss-cross method to assure the two halves of the pump
compress evenly. Tighten screws to snug. |
