6.6. Assembling the water pump
Tip:
We recommend gluing the parts with two component glue or super glue
6.6.1 Glue the magnets in the drive wheel
Note:
Watch the polarity ( See diagram)!
6.6.2 Slide the drive wheel on the motor shaft as far as possible, with its open side facing away from the
motor
6.6.3 Place the motor and drive wheel assembly from above into the pump housing, until the motor is flush
with the housing.
Note:
When assembling the flywheel check the action of the pump, if the flywheel is lightly
turned the motor shaft should turn with it. If does not happen, remove the motor from the
housing and push the drive wheel further on the shaft , re-assemble and try it again
6.6.4 Should the motor move in the housing ( eg. be a little loose) either hold it place with a small bead of
glue, or place a small strip of sellotape around the motor, before inserting it.
6.6.5 Carefully spread a bead of glue all around the base and glue it to the housing
Note:
Be extra careful that none of the glue creeps inside and fouls the flywheel etc!!
6.6.6
Testing
Testing for water tightness, once the glue has set run a brush full of soapy water around the glued
joint. Then blow down the output tube at the same time as covering the input and see if any air bub-
bles appear, if yes, it will need to be re-glued. Dry the pump and re-glue.
