Starter Solenoid; Brush Length; Armature; Brushes - Continuity Check - DeWalt DW168F Manual

sTaRTER solEnoID

Connect a 12V battery between the starter
terminal and the solenoid body and check
for continuity between terminals.
noTE: Continuity should exist when the
battery is connected and not exist when the

Continuity check: commutator segments
Check the continuity between the segments.
If an open circuit (no continuity) exists
between any two segments, replace the
armature.
Continuity check: commutator to shaft
Check the continuity between commutator
and the armature shaft. If continuity exists
between any of the commutator segments
and the armature shaft, replace the arma-
ture shaft.

BRushEs - ConTInuITy ChECk

Remove the armature and check for
continuity between the brushes. There
should be no continuity between the
brushes.

1. Check the overrunning clutch for smooth
axial movement. Apply oil or replace
the overrunning clutch, if necessary.
2. Check the reduction gear movement by
holding the pinion gear (E7) and turn-
ing the reduction gear (U6). The reduc-
tion gear should turn counterclockwise
freely and should not turn clockwise.
3. Check the pinion gear for wear or dam-
age and replace if necessary.
noTE: If the pinion gear is worn or dam-
