Unfortunately it may not be repairable as there are no new spares available at all for Hasselblad 1600 or 1000F cameras and the Russian parts won't fit due to subtle differences in design. Due to the high risk factor (!) I don't repair other folks Hasselblads or the Ukrainian copies - even as it is your Hassy is worth good money to a collector. I'm not sure if you are based in the UK but there is a chap called Tom Page, 01923 800588, who repaired my Pentacon Six for me. Now he may know of someone who could at least dismantle the winding gear and see if a simple adjustment could bring it back to life. Otherwise Euro Photographic Services http://www.ileicestershire.com/profi...phic-Services/ (Ed Trzoska) may be able to help.
