DOUBLE INDEXING ADJUSTMENTS

 

NOTE: All index adjustments must be correct.

 

1. Adjust trip shaft clip left to right for slight pressure on the spring while in the double index mode.

 

2. Form the link in the “U” part so the link has .001”-.020” (0.03-0.51 mm) between the link and the shift interlock bail.

 

3. Tripper Position —

 

a. Adjust tripper left to right for minimum clearance between the spacer and locator.

 

b. Adjust tripper for .020”-.035” (0.51-0.89 mm) clearance to the index keylever pawl.

 

4. Locator Bracket — Form the locator bracket left or right for positive disengagement of the tripper and index keylever pawl, with the mode lever in the normal index mode. (Keylever pawl guides may be moved apart slightly to increase clearance to help get positive disengagement.)

 

5. Locator Clevis — Adjust the locator clevis front to rear for positive engagement of the tripper and index keylever pawl, with the mode lever in the double index mode.

 

6. Carrier Return Interposer Adjusting Screw — Adjust the carrier return adjusting screw for a latch clearance of .005”-.015” (0.13-0.38 mm). If experiencing extra C/R cycles, increase this adjustment to .030” (0.76 mm).

 

7. Double Index Bellcrank (Level 1 Only) — Adjust the bellcrank bracket so the motion of the carrier return latch releases the index keylever without restraining the motion of the carrier return latch when the operational shaft is hand cycled.

 

8. Side Frame Clamp (Level 1 Only) — Adjust the cable cover under the side frame clamp so the index keylever motion is not limited when depressed.
