CORD REPLACEMENT

 

1. Perform cover removal.

2. Remove dust shields.

3. Remove both cords and hand cycle the machine until the mainspring tension is released.

4. Disconnect the carrier return unlatching link.

5. Manually latch the carrier return mechanism and rotate the turning wheel, while counting escapement shaft revolutions, until the mainspring is wound the proper number of turns (Figure 3).

 

6. With the carrier to the right, connect the cord to the carrier return cord drum, position cord to the left over the idler pulley, around the left rear corner pulley and connect to the carrier using scissor clamps or the pusher end of a springhook (Figure 1).

7. Hold the slack out of the carrier return cord and rotate the turning wheel until the carrier goes to the left side frame. Stop hand cycling when the notch in the escapement cord drum is visible.

8. Connect the escapement cord to the escapement cord drum and wrap approximately 1 turn (two turns for 7X3) of the cord around the drum (Figure 2).

9. Thread the cord around the cord tension pulley, and connect it to the carrier.

10. Pull the carrier return cord over the left front pulley and connect the carrier return unlatching link.

11. By using cord anchor, a longer cord can be cut to the proper length.

12. When using the premeasured cords (white), one anchor lug can be cut for easy installation in the cord drum slot. After cutting the cord lug, check for burrs on the lug. If necessary, remove the sharp edges with a file.
