Stihl FS45 string trimmer bump knob - cannot remove

[dukerocks]

I'd like to keep that flex cable from turning when I try to twist off the nut. The only place I can reach the other end of the flex cable is at the motor drive shaft.

You are not going to remove the nut by holding the flex cable. You will just twist the cable and will need to replace it.

So, do you or anybody have a practical solution for removing the nut?

Not all nuts are left handed.
I have some trimmers that the nut comes off going counterclockwise and others that come off going clockwise.

Did you try both ways ?
If the head turns counterclockwise when trimming then the nut comes off clockwise.

Should there not be a hole in the deflector for a locking pin to go into...!

WOW, that makes a lot of sense, I'm hoping you are right about that pin. I did hear something snap when I was using opposing pipe wrenches. I will check that out. Is there a parts diagram maybe showing that pin? Thanks

No, no pin on the curved shaft

Take that back, there is a hole for a lock pin!

Not a lot of plastic/meat there, but it may hold.

Please, somebody correct me if I'm wrong. It seems I should cut off the entire black plastic cutting head to get to the bottom side of the nut?
