198. Starting Motor
a. Description. The 24-volt starting motor is equipped with a Bendix-type drive which automatically meshes with the
flywheel ring gear for starting and unmeshes after starting. The Bendix-type drive is housed in the drive housing. The
armature shaft rotates in three bronze bushings in the commutator-end frame, center bearing and drive housing. The four
brushes are held in brush holders which are an integral part of the commutator-end frame. Torsion springs provide the
proper brush pressure in the commutator. Field poles support the four-coil field coil assembly and strengthen and improve
distribution of the magnetic field.
c. Disassembly (fig. 90). Detach the commutator-end frame (36) by removing the cover band (29), disconnecting the
field coil leads from the brush holders, and removing the through-bolts (39) and lockwashers (38). Tap the commutator-end
