I’d be a little concerned that the sprocket won’t be allowed to “Float” as I believe it was designed to do, which may cause or create some unwanted stresses in the area. Possibly even picking up some added vibration that may transfer into other parts of the trans, bearings, seals, etc?
But, your retainer design looks great and let me know if it doesn't create any other problems.
Well.....as many engineers have said over time, "it looked good on paper."
I logged nearly 400 miles with the revised retainer system only to be disappointed, and wind up with an unwanted, modified sprocket cover. It seems that this retaining system does not like the slop that exists between the output splines and the sprocket. Through trial and error (while carrying various tools with me over the weekend), the design had a bolt back off to make a nice, large hole in the OEM plastic cover (I have a spare) and have a center bolt bounce down the road. Even after replacing the bolts with ones drilled for safety wire, cleaning all parts and using blue Locktite on the threads, and safety wiring everything, the bolts still came loose. Matter of fact, the center bolt had enough force on it, that it broke the 0.025" safety wire THREE times.
It looks like the play in the sprocket, when going back and forth between acceleration and deceleration with engine braking, is acting like an impact wrench and knocking the bolt on the output shaft loose. Also, I ran across two times where one of the smaller bolts worked its way loose, which may have been due to shifting and minor wear of the plates.
It's a shame that this system doesn't work as I had hoped, but at least I tried...and learned from it. I thought about using red Locktite, but I try to avoid the red stuff. I could also go to a larger size safety wire, but I do not want to trust this system to safety wire for day-to-day riding if the bolts are working thieir way loose, so....
Back to the OEM retainer system.
I guess whenever I need to split the cases, I'll probably have to replace this output shaft while I'm in there, because I do not like the additional play from the boogered up output shaft splines.
