SYSTEM DESCRIPTION
The electric starter is a DC motor with a perma-
nent magnet and carbon brushes. The gear-
tooth system of the armature shaft is perma-
nently engaged in the idler gear. During the star-
ting process the sprag clutch forms a connection
to the crankshaft via the idler gear and free
wheel gear. As soon as the engine speed is hig-
her than the speed generated by the electric
starter, the sprag clutch breaks the connection.
SAFETY INFORMATION
- All installation work on the electric starter
must be carried out with the engine switched
off and the battery (negative pole) dis-
connected!
- Ignition, main and LANE selector switches
must be "OFF"!
MAINTENANCE
As well as the maintenance and special checks,
see the relevant Maintenance Manual Line for
the respective 912 i Series engine type.
