Wire Roller Removal

[maverick54]

Hi all, I have an older model Clarke Pro 90 A Mig.

I want to turn around the roller so that I can use 0.6 wire. It is currently set up to use 0.8

I have removed the set screw which holds the roller onto the shaft but it will not come off.

I have tried 2 small screwdrivers behind it in an attempt to prise it off with no luck. I have also givin it plenty of WD40 and allowed it to soak.

Anyone got any ideas please? See Photo

Thanks

Could try some grips on it and try and twist - make see the screw is out , or tap it on a tad and spray with wd again and pit your screw drivers down the back and try to pull off again - and repeat till it’s loose

Fill that grub screw hole up with penetrating oil and leave it over night for a start, it looks like it's rusted on.

I have come across similar, check that there is not another screw under the one you removed .
P.S. just skim a few thou from the O/D of the existing roller, it works perfectly
