| Description and Operation Pre-engaged starter motors of Bosch or Magnetti Morelli manufacture are used. Irrespective of model, all starter motors have an integral solenoid and all types have pinions which engage with a ring gear during starting. The ring gear is located on the outside of the flywheel. Some starter motors are interchangeable in certain circumstances, refer to the Parts Microfiche for detailed information. Starter motors should be serviced as an assembly and should not, therefore, be dismantled. |
