The wind mech has 2 claws (ZJ1291) which catch on the main wind gear
(CA9375). Sometimes the gear tips have been broken off, which means the
claws slip over instead of grabbing. This is usually caused by forcing
the wind mech, not normal wear. A side problem is that all those tiny
metal chips would be floating around inside the camera (which could get
stuck in the grease on other gears or ending up stuck the the magnet
inside the meter). This is probably not your problem.
Also, the movement of the 2 claws relies on 2 smooth rings (CA8757)
ability to slide on each other while under light spring tension
(CA8763). These 2 smooth rings often get stuck together, preventing the
claws from engaging the wind gear.
