Design
•
Pre-engaged style of a starter motor in
the medium duty version; two-stage
engagement in the heavy duty version.
•
Nosed or noseless versions for specific
engine applications.
•
Electrical excitation of the motor part.
•
Drive assembly with a six roller clutch.
•
Rubber shock absorber, low-noise,
metallic planetary reduction gear with
pinion and armature in one axis.
•
Pinion shift mechanismwith solenoid,
fork lever and helix.
•
Solenoid switch with pull-in and hold-
in winding is designed for effective
breaking of the main contacts.
•
High quality thermally resistant
materials.
•
Drive end brackets made of grey cast
iron (GCI), nodular cast iron (NCI) or die
