Hi All, I just got my new belt for my Singer Model 66 treadle. My husband helped install the belt, but he is concerned that it is rubbing against the cabinet and will wear the belt out quicker (see pictures). Does anyone have any information on how to adjust the horizontal position of the treadle wheel so the belt doesn't rub? It doesn't have to move much. I have searched the forum and internet, but all I come up with is how to replace the belt and not adjust the location.

Thanks,
Shari
