So he helical gears in their respective ratios are free on the mainshaft, on bearings.and The helical teeth are permanently engaged.....the shifter fork moves the synchro cone....given the mainshaft is properly disengaged from the power source, the friction of the synchro cone will adjust the mainshaft rpm to match the layshaft rpm ....the detent ***** detect there is no drag between he shafts, allowing the dog gear and hub to ENGAGE in a traditional metal on metal dog clutch fashion. This engagement results in the gear being locked onto the mainshaft, power can be applied to the mainshaft again, and off we go.

Question....if there is going to be a dog clutch engaging and disengaging, why not just have those dog gears the right sizes and do away with the helical gears altogether. I mean, the helical gears are strong and quiet, but actually, there is weaker point....the dogs...that power has to go through anyway...

 

price.

 

What does questioning the dog clutch operation (engagement teeth) have with doing away with the helical cut of the ratio teeth? LOL Two seperate issues.
