Locking ring SGA 16 for sprockets etc.

You need two. From chassis number 9229673 Dakota/VZ50 (mid 1971) the nut on the pinion shaft disappeared and was replaced with 2 locking rings. Mid 71 also applies to other Puch. Replace the locking rings when replacing the sprocket, they get worn and enlarged with age and increases the risk of breaks. Sold individually. No. 15 on Puch spare part image. Also fits many other places. I.e. at the Sachs pedal axle with the original number 1024502-0001. Number 1 on Sachs exploded view. Please note that the standard SGA 16 probably is slightly narrower than the original but it still works as you use shims at the sprocket.
