Dee,
Oooops!...Unscrewing the housing block was a bad idea. This is usually set with
a fixture which us techs had to purchase and pay for the training on how to use
them to adjust the selector/knife assembly for proper operation.....
The top thread is not trimming because you now have the housing block not
adjusted properly and when the selector fires it is not separating the triangle
made by the top thread up to the bottom of the garment where it has tied onto
the bobbin thread, therefore not allowing the hook on the selector to pick up
the one top thread that is suppose to get cut, but is picking up the bobbin
thread and pulling it back to where the knife will fire and cut it. This
triangle /\ is very small and everything must be right for the selector to
separate it correctly.
The housing block should not have been loosened, it was not necessary. Don't
get me wrong, I am not verbally chastizing you here....it is that you just did
not know. It is difficult, with a machine that using timing in every part of
it's function, to not affect something else when another part is moved or
adjusted, messed with or whatever. The new knife is placed into the knife
carrier after removing it from the machine and then placed onto the pushrod
wire, laid down on top of the housing block and then the spring clip replaced
to hold every thing together, in that order. The push rod wire is attached to a
stepper motor deep in the back of the machine, that drives it back and forth
and will not pull forward without the motor driving it.
You have two choices at this time. Call for a tech to re-adjust the housing
block, or... keep experimenting by loosening the housing block and
moving(rotating) it slightly. It does not have much movement left or right
because it has a guide pin to hold it in place, but there is some and it's
positioning is "extremely critical" for the trimmer to function
properly.......did I say "extremely critical" !!! It really is....
