Take off the three screws >>> shown. >>> >>> Then, clean out the gears around. Turn the shutter to B or 1/60 >>> (manual setting). >>> >>> If you press the shutter release, you'll see that the thin bar to >>> the bottom of the photo moves. There is a pair of lever under >>> the silver gear that also moves. If you move the top and >>> bottom, you'll see that the film advance frees up. That is a >>> great essential first step. >>> >>> Also look at what the big thick bar is doing. It activates the >>> mirror movement, and it needs to move too. Take this opportunity >>> to study the mechanism and clean things. >>> >>> On my camera, the reverse lock (forked) lever was completely >>> loose. It is also under the silver gear and needs to move >>> freely. You need to remove the mirror mover bar, via its big >>> cross-head screw. THIS SCREW IS A LEFT HAND SCREW !!!!! Remove >>> the bar and secure the reverse lock (forked) lever. >>> >>> Then put the mirror lever back into place. >>> >>> Now, the camera gears need to be timed correctly. You will find >>> that the film advance finishes in 3 positions. One is the >>> correct one - and it ends with the rabbit ears of the silver gear >>> in the right place, per the photo. >>> >>> Under the synchronization plate (that you've removed), you'll >>> find the shutter tension drum. Advance it to the tensioned >>> position - it will click into place. Advance the film advance to >>> the right place. Now re-install the synchronization plate, with >>> the gears in the right place and the cutouts in the correct >>> orientation. >>> >>> Now it should all work. >>> >>> >>> >>> _______________________________________________ >>> Leica Users Group. >>> See http://leica-users.org/mailman/listinfo/lug for more information >> >> >> _______________________________________________ >> Leica Users Group. >> See http://leica-users.org/mailman/listinfo/lug for more information > > One sees clearly only with the heart.
