Inspection And Repair - Tecumseh V-twin Technician's Handbook

5. Remove the through bolts holding the commutator
end cap assembly on. (Illust. 5-16)
6. Slide off the end cap assembly. The starter terminal
post insulator slides out of the commutator cap on
some models. (Illust. 5-17)
7. Remove the armature.
8. Inspect and replace as necessary, see the section
"Inspection and Repair" later in this chapter. Use the
reverse procedure for assembly. For ease of
assembly, place the armature into the brush end of
the frame first.

INSPECTION AND REPAIR

1. The 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 in soap
and water) to remove dirt and grease, and dried
before reassembly. Also check the armature and
drive nut splines for wear or damage.
2. The brushes and brush cardholder should be
checked for wear. With the armature placed in the
commutator end cap, and the brushes engaging the
commutator surface, check the brushes for wear.
5-16
Brushes should be replaced if the brush wire
approaches the bottom of the brush holder slot. Brush
springs must exhibit enough strength to keep tension
on the brushes and hold them on the commutator.
3. Using a continuity light or OHM meter, check field by
attaching one lead to each of the field coil
connections. Continuity should exist between these
two points. (Illust. 5-18)
