Frantisek Jiracek 4 speed transmission

Pretty much anything not covered by the topics above. Short lived production bikes or vehicles, Electrical, Tires, Paint, Brakes, etc. Use this for tech questions, and "Shoot the Bull" for general conversation, no tech.

Pa, i checked my measurement with your drawing. Measurements are the same, but cold not find inner race length on your drawing. And dit not underststand the 5.0625" diameter.
I could not find the rason for lack of distance between lip of trust bearing race and end of race. Closed gap by installing a roller trust washer.
Some fiddling with the shifter forks to get them adjusted. Could not use the OEM specs.
Installed in frame, ready for the road.


Thanks to Pa and ralph for your support.
