i got a km 2 speed rev 30.5 and it wont move i think its the spur gear. any one know were i can get a new one please help im new to this
 
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.

theres k,m one way bearings on ebay but whats the point buying another k,m one if they don,t last is there a code on the bearing if so you could get one from a bearing shop theres a few on ebay with fast delivery.
 
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.

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
