Hi: I've dismantled the reel and the hollow axle of the reel appears to be broken internally and easily comes apart from the back plate. I've tried re-assembling it and it still seems to work – though the reel alignment is a bit sloppy (which may be why it jammed in the first place). Please can you kindly advise if the reel axle is intended to split like this? I don't want to re-assemble it only for it to jam again, and am happy to replace it if it's really broken.
