4.2 Routine Maintenance: Gearmotors fitted to the Drive
Generally, the gearmotor does not require routine maintenance other than periodic brush
replacement on our Standard DC models. Apart from these brushes there are no service parts
available. Should the DC gearmotor fail (or separately the motor or gearbox), we recommend the
whole DC gearmotor be replaced with a new unit, available from Solar Injection Australia or an
SiA distributor.
We recommend that the brushes be inspected as often as practical until the operator obtains
experience of the expected brush life for each situation, but at least every 6 months.
Note: There are no brushes in a BLDC Motor.
To inspect and or replace brushes on our Standard PMDC Gearmotor models, please follow the
steps below:
1. Disconnect power to pump before any servicing takes place.
2.
Use large flat blade screwdriver to unthread the plastic caps on either side of the motor.
3. Remove the brushes carefully (they are spring loaded).
4. Examine them. They should be at least 1/8” thick. If they are not, replace them. They will not
last much longer.
5. Replace new brushes into the holes on either side of the motor’s outer shell and rethread the
plastic caps.
6. As with the moving internals of the Drive, the operator can expect longer service intervals and
life by keeping the gearmotor clean and dry.
WARNING
: Should the gearmotor show signs of wear in any way it should be replaced
immediately with new parts available from Solar Injection Australia or SiA Distributors.
