1 • Remove the covers.
2. Position the carrier to the extreme right.
3. Remove the degree wheel pointer (#1, Figure

4. Remove the degree wheel (#2, Figure 1).
5. Remove the gear guard (#3, Figure 1).
6. Remove the left dust cover (not shown).
• 7. Remove the two screws (#1, Figure 2) that hold the con-

9. Remove the front screw from the C 1 - C2 contact assemblY
(#1, Figure 4) and swing the assembly down out of the way
of the bearing plate.
10. Remove the cycle-clutch check pawl and spring (#1,
Figure 5).
11. Remove the three bearing-plate screws (#2, Figure 4).
12. Remove the bronze intermediate gear (#3, Figure 4).
13. Remove the Cl -C2 cams (#4, Figure 4) and the cycle
shaft gear (behind the C 1 - C2 cams).
14. Remove the bearing plate (#5, Figure 4) by prying it away
from the frame (front end fi rst) with a screwdri ver and
sliding it off the cycle shaft.
,15. Force the positive bail down with a screwdriver (#2,
