smg pump motor
NEW replacement motor only
This is a direct replacement bolt in and slide pins into BMW connector*
We use this motor in our rebuild kits and offer it for DIY service, designed specifically for SMG duty cycle to handle high torque of 90bar (1300 PSI) pressure requirements.
Kit Includes:
- 1 High torque DC motor
- 1 Drive coupler
- 2 new installation screws
- 1 Sealing gasket
- 1 Grease packet
- 1 year warranty
*Does not include pin extractor tool, see our other item sold with extractor tool.
90% of SMG pump failures are due to motor malfunction and system pressure loss.
Replacement of SMG relay is highly recommended anytime there is a motor failure. Not doing so could cause erratic switching on/off times of pump and lead to damage of new components.
