I have two wm-f57. One is my original one from 1989, thr other I just got. Both have dissolved belts. I have a selection of belts, but am unable to figure out the belt routing. Does anyone have a photo or something to help me get them working again. The radios work great. Thanks.
Hyperscope, Thanks for the info. Found a belt layout from a different model, but looked like mine. That black pulley in the upper right corner was the key for me. Attached are photos of my 57 and a 77. View attachment 45860
The mechanism is very similar (possibly identical) to WM-55. To be noted belt in the first pictures looks too thick for this mechanism, it needs to be the one pictured in Reddit post (0.6mm thickness). Also, this mechanism is very likely to need a new idler tire: https://fixyouraudio.com/product/idler-tire-for-sony-wm-55-walkman/ For idler location, check this thread: https://stereo2go.com/forums/threads/sony-wm-55-playback-problem.7003/
