Bent shaft

Question

I shipped my Bernina 1008 over seas and now when I tighten the handwheel it "wobbles" when rotated, the belt tightening and loosening with every rotation. If I loosen the handwheel it spins fine. I live in PNG so I will have to fix it myself, but I haven't been able to find a parts brakedown yet to figure out the parts I need to order. Thanks for any help you can [e-mail]
