The shaft on which the oscillator knob of my GE FM9V1 sits is bent, so I’d like to remove the assembly and straighten the shaft.   However, I can’t figure out how the knob is attached to the shaft, nor the sleeve attached at the other end (see picture, lower left):



Before I started messing with this assembly, I wanted to ask the forum for advice. Is the connection a press fit, or a left-hand thread, or what?

The Knob is a press fit - you'll have to carefully heat it to remove

Thanks for the tip, John. I’ll look at the assembly for the best way to pull the knob from the shaft.

A follow-up question; is the shoulder screw that connects the oscillator arm with the oscillator disk, a left-hand thread? I need to find the screw, but it appears to be left-handed? Is it a 6-32 NC thread?

I don’t have the thread but it is left handed. It looks like Darryl Hudson shows one on his site for sale. Described as: [size=GE, Vortalex arm to wheel shoulder screw, LH thread………… $20.00 ea.​# GEVS1]

I saw that, but I believe it’s a bigger screw for the larger Vortalexes.  I’ll send him an email to confirm, though.  

Thanks!
