Heddle Bar Hook for Wolf/Standard Floor Looms

You will need a flat (slotted) screwdriver; 3/8" or adjustable wrench; spirit level.

1. Remove heddles and heddle bars from the shaft: thread a string through the tops of all heddles and tie the string securely; repeat at the bottoms of all heddles. Pulling down on the heddle hook(s) of one heddle bar, bend the bar gently in middle to release one end and slide the other end out. Repeat for the remaining heddle bar. Set the heddles and the two bars aside, keeping the heddles on the bars.
2. Unscrew the old heddle bar hook by hand; if it will not turn by hand, use the blade of a butter knife or a flat (slotted) screwdriver.
3. Insert the new heddle hook in the hole and use a 3/8" or adjustable wrench to screw it firmly into place.
4. If you are replacing old-style heddle bar hooks—they will not look like the ones in the photo above or the new ones you received—you will need a drill and a 9/64" bit. Enlarge the hole the old-style hook fit into with the 9/64" bit.
5. Carefully reinstall the heddle bars and heddles in the shaft frame.
6. Use a level to make sure the heddle bar on the new hook is parallel to the shaft top and bottom; it should slide a tiny bit from side to side. If necessary, adjust the height of the new hook with a screwdriver. Then pull the lock down, insert the heddle bar onto the hook, and release the lock upward. Repeat this process until the bar on the new hook is level.
