I would also like to mention that the assembly ( I find) easier in second (yes!) neutral position between 3rd and 4th gear.
Same way it goes together for all Jawa 250 and 350 models from 1946 to about 1973. Gearbox of models made after 1970-73 is different only in number of teeth on gears and shape of shifting forks , otherwise the same process. Same goes for all street CZ motorcycles.
125 and 175 models are also very similar, just slightly scaled down. Hope this video is helpful, since English instruction manuals that describe this process in detail are somewhat hard to find, and most mechanics on this side of Atlantic will not touch those obscure bikes with a ten foot pole..
Any other questions regarding repairs on mentioned motorcycles are welcome. Engine has very simple iternals , especially the single cylinder models, and are easy to work on. Unlike most people think there's lots of new aftermarket parts available from Czech Rep and Europe for almost any model, and quite inexpensive - to North American standards.
