I bought the model fisguring it would be a neat project. After the bearings were just about stripped due to the other bearings coming undone I decided to glue them in. Next I went to attach the cam gear to the crank gear and the pieces don't line up, they are off by about 5 MM, not much but enough so that they don't even touch. The cam gear is too far back, or the crank gear is too far forward. Either way I haven't progressed very far in the 3 hours i've worked on it. Any help is much appreciated.
