II. Adjust Cycle Shaft, Filter Shaft, Print Shaft Timing

 

1. Tighten cycle clutch gear, observing full lateral mesh and enough clearance between cycle clutch gear (47-35) and cycle clutch left bearing to prevent binds.

 

NOTE: Remember, the cycle clutch gear does not control the end play of the cycle shaft. The end play is controlled by shims (1-1) on early level machines and by a collar on late level machines.

 

2. Rotate the cycle shaft until:

 

 1. the high lobe on the negative 5 cam (124-18) is approximately vertical, and until

 

 2. the cycle clutch check ratchet (124-19) is backed up against the cycle clutch check pawl (124-20).

 

When the above two conditions are met, the cycle shaft is in the rest position.

 

When the cycle shaft is in the rest position, you are ready to adjust the filter shaft (55) and the print shaft (70-39).

 

3. Adjust the filter shaft for .015" clearance between a latched down interposer and the filter shaft. Observe clearance between the filter shaft gear (47-34) and filter shaft left bearing when the filter shaft gear is tighten.

 

4. Adjust the print shaft (70-39) so the keyway is in line with the pertrussion (41-21) on the left side of the carrier. (This is only a preliminary adjustment).

 

5. Next, you have to perform a very important step; rotate the cycle clutch spring to the rest position.

 

 1. Using the pusher end of a spring hook, rotate the turned up ear (136-30) on the left end of the cycle clutch spring top to front until the turned up ear (136-31) on the right end of the cycle clutch spring is resting down against the bottom edge of the window in the cycle clutch sleeve (136-32).

 

 NOTE: For a check to see if the cycle clutch spring is at rest, do the following:

 

 1. With your turning wheel, slightly rotate the machine top to front, while observing the cycle shaft; If

 

         1. the cycle clutch spring is at rest, the cycle clutch shaft will remain stationary.

 

         2. the cycle clutch spring is not at rest, the cycle clutch shaft will start to rotate also.

 

If the cycle clutch shaft starts to rotate, STOP!

 

If the cycle clutch shaft moved, it is no longer at the rest position. Therefore, the cycle clutch shaft must be returned to the rest position.

 

In order to return the cycle clutch to the rest position, do the following:

 

 1. With your fingers, rotate the print shaft top to front, until the cycle clutch ratchet (124-19) is backed up against the cycle clutch check pawl (124-20). The cycle clutch shaft is now back in the rest position.

 

If the cycle clutch had to be reset, go back to adjustment 5.

If the cycle shaft did not move, go to adjustment 6.

 

6. Adjust for .010" clearance between the cycle clutch pulley hub (136-33) and the cycle clutch spring (136-30).

 

7. Adjust for .015" clearance between the cycle clutch pulley hub (136-33) and the cycle clutch sleeve (136-32). Then go to 1 below.

 

8. A. Too much movement - Grab print shaft and slightly rotate top to rear.

  B. Not enough movement - Slightly rotate print shaft top to front, then push down on left ear (136-30) of Spring. After A or B go to 1 below.

 

9. Adjust the cycle clutch overthrow stop, left to right (63-25) for .010" clearance between overthrow stop (63-25) and cycle clutch sleeve (63-24).

   At the same time, radially adjust a clearance of  .010" between the cycle clutch sleeve and overthrow stop (63-28). Tighten the clamp (63-26).

 

TO CHECK ADJUSTMENT OF CYCLE CLUTCH SPRING, DO FOLLOWING:

 

1. Depress the bracket keybutton and rotate the cycle shaft, with the turning wheel, until the cycle shaft stops rotating.

 

2. Depress the bracket keybutton again; lay your finger on the cycle clutch check pawl (124-20).

   Rotate the turning wheel slowly, while observing the movement of the print shaft gear (47-38) - the gear should rotate 1/2 to 1 tooth as the cycle clutch check pawl (124-20) falls under the cycle clutch ratchet (124-19).

 

If the cycle clutch spring adjustment is not correct, go back to adjustment 8. If the cycle clutch spring is correct, go back to adjustment 9.

 

NOTE: When the cycle shaft is rotated with the turning wheel, the cycle clutch check pawl (124-20) should not fall under the cycle clutch ratchet (124-19).  The check pawl should fall under the ratchet only under power.
