Cleaning and Inspection
1. If brushes are pitted, chipped or worn to less than 3/16 in. (4.8mm), replace brushes.
IMPORTANT: DO NOT clean the starter drive assembly or armature shaft while
starter motor is installed on outboard. The cleaning solution will drain dirt into mo-
tor housing.
2. If the motor drive assembly does not fully engage with flywheel, the drive assembly
may be binding on the helix threads on the armature shaft due to dirt or wear. Locate
cause of binding and correct before reassembling.
3. Clean drive components with cleaning solution and inspect parts for wear.
4. Clean commutator with No. 00 sandpaper. Remove any oil from commutator. If com-
mutator surface is pitted , rough or worn unevenly, resurface on a lathe.
5. Resurface commutator on a lathe as follows:
a. Use a lathe to turn down the commutator surface. DO NOT turn down the commu-
tator surface excessively.
b. Clean copper particles from slots between commutator bars.
c. Sand the commutator lightly with No. 00 sand paper to remove burrs. Thoroughly
clean the armature after resurfacing and sanding.
