EQ3-2 Polar-scope - How do I fit it??

[ian61]

I am probably about to look very silly because I can't find anyone else who seems to have a problem there is likely an obvious solution. The only video I could see of a similar mount being fitted with a polar-scope is to an EQ5 and the chap simply unscrewed the assembly and replaced with the polar scope. It is clear this needs to happen so as to replace the scale ring. However twist through I did all I achieved was to remove a collar (I had loosened the grub screws) and that allowed the scale to slide off but there is still black tubing that surely I need to remove - but how? any ideas gratefully received.

(there were three small knurled screws on the end of the black tube removed before 1st photo taken)

Put the 3 screws back in and use them as leverage to twist the assembly out.

Gee that was stiff but it did work thank you very much.
