Can you make a video like this one but on different topic - "Speed gears free play in manual transmissions". I think the setup of amount of free play on speed gears is critical for a good gearbox rebuild. Also the comment before me stated "input shaft float" i think he meant to say- shaft end play, which is also important setup , but i don't know why either.
You might find some of what your looking for with speed gear clearance in one of the videos in my manual transaxle overhaul play list. ru-vid.com/group/PLBj7r2PaWTNhftt7u6QeZYqAwgO4vu8RG The videos in the series that have to do with output shaft or input shaft assembly show measuring for proper speed gear thrust clearance. I will look into something with a little more generic about thrust clearances on speed gears and shafts such as input shaft, output shafts, counter shafts and main shafts.
