7. Install the new reciprocator into the head (see Figures 3-31 and 3-32). Make sure
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).
9. Install the needle bar guide shaft as follows (see Figures 3-31 and 3-32):
a) Insert the guide shaft down through the hole in the top of the head.
b) Insert the guide shaft through the reciprocator.
c) Insert the guide shaft down through the roller bearing.
10. Reinstall the retaining clip onto the needle bar guide shaft (see Figure 3-32).
11. Turn the needle bar guide shaft until the flat near the top faces the left side of
the head (see Figure 3-31).
12. Pull the needle bar guide shaft down until it seats into the lower hole. Be certain
the retaining clip is located low enough so the reciprocator will not hit it during
its down stroke and the roller bearing is loose enough to rotate freely.
13. Tighten the set screw on the left side of the head to secure the needle bar guide
shaft (see Figure 3-31). Reinstall the felt in the hole in the arm casting.
