Remove, inspect and replace as necessary. Use
reverse procedure for assembly. (For ease of assembly
assemble armature into brush end frame first.) Place a
small amount of light grease such as lubriplate between
the drive nut (3) and helix on armature shaft. DO NOT
apply lubricant to pinion driver.
ELECTRIC STARTER REMOVAL. Remove face plate,
air cleaner assembly and gas tank. Compress plastic
grommet and pull it out of the blower housing. Slide the
wire through slot, being careful not to cut the wire
insulation. Remove blower housing, remove flywheel
(see flywheel section) and inspect ring gear for wear or
damage. Replace if necessary (see flywheel section).
Remove nuts on both sides of pinion. Drop starter out
of back plate and remove ground wire.
DRIVE ASSEMBLY SERVICE. Pinion gear parts should
be checked for damage or wear. If the gear does not
engage or slips, it should be washed in solvent (rubber
parts cleaned with soap and water) to remove dirt and
grease, and dried thoroughly. If damaged, replace parts.

CHECK BRUSHES. Before removing armature, check
brushes for wear. Make sure brushes are not worn to
the point where brush wire bottoms out in the slot of
brush holder. Brush springs must have enough strength
to keep tension on the brushes and hold them against
the commutator. If brushes are in need of change,
replace the entire end cap assembly.
ARMATURE CHECK. If commutator bars are glazed
or dirty, they can be turned down in a lathe. While
rotating, hold a strip of 00 sandpaper lightly on the
commutator, moving it back and forth. (Do not use
emery cloth.) Recut grooves between commutator bars
to depth equal to the width of the insulators.
Using a continuity tester to make certain no continuity
exists between the commutator (copper) and the iron of
the armature, rotate armature and check out all
commutator bars.
The armature can be thoroughly checked with a growler
if available.
