Replacing Reciprocator / Needle Bar Guide Shaft
1. Remove the needle case as described previously.
2. Loosen the set screw from the left side of the head that secures the needle bar
guide shaft (see Figure 3-19).
3. Remove the retaining clip from the groove in the needle bar guide shaft.
4. Remove the felt from the hole in the top of the arm casting, then remove the
needle bar guide shaft by sliding it up and through the hole.
Note:
If you are only replacing the needle bar guide shaft, proceed to step 8.
5. Remove the reciprocator from the connecting rod by pulling it straight out of the
head. Discard the reciprocator.
6. On the new reciprocator place a drop of machine oil on the reciprocator
connecting stud (located on the lower back side of the reciprocator).
7. Install the new reciprocator into the head. Be certain it is oriented properly and
insert the connecting stud onto the connecting rod.
8. Add two drops of machine oil onto the needle bar guide shaft (or new guide
shaft if replacing).
