NOTE: Inspect the entire circumference of the
ring gear for damage when the teeth of the drive
mechanism pinion gear are damaged. A normal
wear pattern will be found in three places on a
six-cylinder engine. The normal wear pattern
extends approximately 5cm (2-in) along the
circumference of the ring gear.
Inspect the drive mechanism overrunning clutch
by grasping and rotating the pinion gear. The
gear should rotate freely in the clockwise
direction and lock in the opposite direction.
Inspect for broken brush springs. Replace
springs that are discolored from the heat.
Replace the brushes if they are worn down to
6.35mm (1/4-in) in length.
Inspect the field windings for burned or broken
insulation and for broken or loose connections.
Inspect the field brush connections and the wire
insulation.
Field Winding Removal
Remove the armature and brush holder before
starting this procedure.
Remove the field winding screws using an arbor
press and Starter Pole Screw Wrench J-22516.
Remove the pole shoes.
CAUTION: Do not cut the solenoid contact point
connection joint.
Cut the field winding terminal strap as close as
possible to the solenoid contact-point-to-field
winding joint.
Cut the hold-in coil winding terminal wire at the
terminal strip.
Straighten the tabs of the pull-down coil winding
sleeve. Remove the sleeve and flange.
Remove the field winding assembly from the
frame.
Field Winding Cleaning and Inspection
Clean and tin the surfaces of the contact tab and
the field winding terminal strap that are to be
soldered.
Field Winding Installation
Install the replacement field winding assembly in
the frame using the original pole shoes and
s c r e w s . Apply a drop of Loctite 2 2 2 , or
equivalent, to the screw threads. Tighten the
screws using the arbor press and Starter Pole
Screw Wrench J-22516.
Install the pull-down coil winding sleeve and
flange. Have a helper hold the winding and
sleeve assembly against the frame while
bending the retaining tabs.
Wrap the hold-in coil winding terminal wire
around the terminal strip and solder. Cut off the
excess wire.
Solder the field winding terminal strap to the
contact strap. Use a 600 watt soldering iron and
rosin-core solder.
