hi and welcome to lsf, have any of the gears lost teeth ? if not check the internals of the gearbox rc modelz should do the spare parts, sometimes it less hassle to just run single speed.

Are you sure that is the corect bearing on the pic it seems to just have 1 notch on the inside the 2 speed bearings I have have 2 notches not sure if that matters or not.

i have had mine out for quite a few runs and the 1 way bearing on mine is still in good shape.

Yes mine has last a very long time its how the gear mesh is set that is very important from the factory the gear mesh from the km are tight and cause the bearing to go out very quickly. If you remove the gears and mesh the gears right a lil loose the bearing will last.
 
Was the bearing the same size other than only having one notch on the inside I was gonna modify the second notch at work if there the same size since I ordered it already and order the right one says it won't b here till jan anyways thanks
