i was going down the road and i thought my clutch went out. I released the clutch and nothing. It just squealed and slipped so i got home and took clutch cover off. On the left side motor and when i took cover off bolt and drive gear fell out. Of the cover so i put it back on didnt notice the key gone so i got it running again .And my bolt kept backing out with out the key. It does ok got it home again and took off cover and again it all fell out. I got mad then with a flash light got looking and around the clutch behind it in the bottom there was a key. I got to looking didnt know where it came from then i looked at my drive gear and son of a gun there was a place for a key. And in the shaft to cool so it took 30 minutes to get that tiny key in that tiner hole. In the shaft and the gear back on it so i thread locked the screw in the shaft and key. In the shaft also so maybe this will hold it all together. Any body have problems with the key coming out of the drive gear and if so how you fix it ?
