TEST FOR GROUND
IMPORTANT: Be sure that positive brushes and
leads do not contact field frame assembly during
test, or false reading will result.
1. With continuity meter, place one lead on field
connector bar and other lead on grounded brush.

2. If meter hand moves, field coils are grounded and
must be replaced.
Loose Electrical Connections
If open soldered connection of armature to commuta-
tor leads is found during inspection, resolder with res-
in flux.
IMPORTANT: Never use acid flux on electrical
connections.
Turning the Commutator
When inspection shows commutator roughness,
clean as follows:
1. Turn down commutator in a lathe until thoroughly
cleaned.
2. Recheck armature for shorts as outlined.
Reassembly
After all parts are thoroughly tested and inspected
and worn or damaged parts replaced, reassemble
starter as follows:
1. Assemble brushes and related parts to field
frame as follows:
a. Assemble brushes to brush holders. Attach
ground wire to grounded brush and field lead
wire to insulated brush.
b. Assemble insulated and grounded brush
holders together with V-spring. Position as a
unit and install support pin. Push holders and
spring to bottom of support and rotate spring
to engage center of V-spring in slot in support.
2. Assemble over-running clutch assembly to arma-
ture shaft as follows:
a. Lubricate drive end of armature shaft with
SAE 10W oil.
b. Slide assist spring and clutch assembly onto
armature shaft with pinion outward.
c. Slide retainer onto shaft with cupped surface
facing end of shaft (away from pinion).
d. Drive snap ring onto shaft and slide down into
groove.
