Starter and Charging System

Rebuilding the starter
The starter motor used on the 4P90 engine is a perma-
nent magnet dc motor with a radial commutator, similar to
what is found in a repulser start motor. A radial commuta-
tor means that the commutator plates are perpendicular to
the axis of the rotor.
With this arrangement, the brushes and brush holder
are mounted to the end cap and the rotor will ride on top of
them.
Starter motor disassembly:
1. Remove the starter by following the procedures
described in the starter removal section of this chap
-
ter.
2. Put alignment marks on the stator housing and the
starter gear housing.
3. Put an alignment mark on the end cap and the stator
housing.
See Figure 6.5.
NOTE: The starter will not work properly if the stator hous-
ing is put on upside down. Vary the alignment
marks to prevent this.
4. Remove the end cap using an 8 mm wrench.
