Service; Volt Or 120 Volt Electric Starters With Exposed Shaft; The Cap Assembly - Tecumseh ECV105 Technician's Handbook

SERVICE

This section covers the service procedures for the 12 and 120 volt electric starters. For diagnosis of the starting circuit
see "Electrical Starter Troubleshooting" in this chapter. Illustrations may not be identical in configuration to the starter
being serviced, but procedures and tests apply unless otherwise stated.
12 VOLT OR 120 VOLT ELECTRIC STARTERS
WITH EXPOSED SHAFT
1. Remove the plastic dust cover on the armature end
(diag. 34).
2. Push down the spring retainer and remove the
retainer ring.
3. Slide off the spring retainer, anti-drift spring, gear,
and drive nut.
4. If internal service is necessary, scribe a line across
the cap assemblies and armature housing to aid in
reassembly.
5. Remove the two or four retaining nuts from the
through bolts holding the cap assembly.
6. Slide off the cap assembly. The terminal insulator
slides out of the commutator cap.
7. Remove the armature.
8. Inspect and replace as necessary.
9. Use the reverse procedure for reassembly.
10. Inspect flywheel ring gear for damage before
installation.
12 VOLT D.C. OR 120 VOLT A.C. ELECTRIC
STARTERS WITH CAP ASSEMBLY
1. Remove the retainer ring from the armature shaft
(diag.35).
2. Remove the two nuts from the through bolts holding
the cap assembly on.
3. Slide off the cap assembly. The engaging nut, gear,
spring, and spring retainer will remain in the cap
assembly.
4. If complete disassembly is required, refer to step # 4
in the previous section for additional steps.
5. Inspect and replace as necessary. Use reverse
procedure for assembly. ( For ease of assembly, place
the armature into the brush end frame first.)
6. Inspect flywheel ring gear for damage before
installation.
