A friend bought an optical quite nice Adler 167 from an insolvent company. Unfortunately the machine is technically totally out of time and needs a new timing belt as it is quite brittle. Seems it once was used as a binding machine. I promised to help him but I thought it would be the same as at my Singer 111 but seems the Adler 167 bearing at the hand wheel is not removable. Machine has some more issues but I think w/o a new timing belt it makes no sense to do further adjustments. Can someo
