General Maintenance
The hook assembly itself will be difficult to remove because the three set screws you just loosened have scarred
up the hook shaft. To remove the old hook, look down through the hole in the throat of the machine, and locate
the hook shaft coupler that is on the shaft behind the back of the hook assembly. The “air gap” between the
coupler and hook assembly will be used to remove the old hook assembly.
If the air gap is small, use a flat blade screwdriver to open the gap. From
the top of the machine, insert the tip of a flat blade screwdriver in the
space between the back of the hook assembly and the hook coupler, and
twist the screwdriver’s handle – this will open up the space between the
two pieces.
