I'm a newbee with an Adler 067 that I am attempting to change the timing belt. I have the hand wheel removed THANKs to photo provided in this thread by Greg from Keystone Sewing. I assume the shaft needs to be removed in order to get the old belt off and the new belt on. Can anyone provide me with photos or directions as to what to do next as I do not have a manual for my machine but this site has been very informative. Thank You All for you input.
