Yes, there’s a link “post and pictures here” that should take you to it.
In the first picture you can see the plastic cassette has broken in two.
In the second picture you can see I’ve attached some metal braces to fix the cassette, plus the 1-1/4" hose clamp to keep the ends of the cassette’s plastic shaft together (the hose clamp is what I suggest to strengthen a still-functional yoke).
In the third picture you can see I’m pushing in the yoke and how that translates to internal movement. Without any reinforcement, pushing the yoke in stresses the cassette: all force from the spring appears to transmit to the screw in the middle of the plastic cassette. Its shaft would want to spread apart in that case, and the clamp helps brace it.
Hope that helps.
