Procedure to Identify the Closest Needle
When the needle case has been replaced, it is necessary to reestablish the closest needle and make sure
that it falls under the total allowable variance of.006. The following is the procedure to identify to the
closest needle:
1.
Perform the following procedure: Use the dial indicator from the take up lever stroke fixture (PN
32413), remove it, and attach it to your head timing gauge (PN 32453-01).
2. Assemble the head timing gauge (PN 32453-01 to the XT head timing adaptor (PN 33065) as
shown in Figure 1.
Figure 1
3. Remove the needle plate (PN 33111).
4. Remove the bobbin case (PN 004267-01).
5.
Mount the closest needle gauge fixture to the lower arm extrusion. It should appear as shown in
Figure 2:

6. In the software, enter the Maintenance Menu.
7. Under the Maintenance Menu, enter the Head Timing Menu.
8. YOU MUST PULL OUT THE PLUNGER of the closest needle dial indicator and KEEP IT HELD OUT as
you hit the Frame Back button on the keypad of your Machine machine. See Figure 3 for an exam-
ple of holding the plunger back.

NOTE:
If you exit the needle depth subroutine at any time, you need to close the Head Timing
Menu in the software and reopen it to re-enter the needle depth subroutine. Press the frame
back button while holding the plunger out to re-enter the measurement routine.
