Are there any seals that sit behind the countershaft sprocket? Last weekend I was out riding, and My chain broke. It snapped and jammed in between the case and my front sprocket. I took the old chain and the sprocket off to put on a good chain in the middle of the woods just to get me home. I reinstalled a new chain and front sprocket, and now it is leaking like crazy. I didnt notice which way the sprocket goes on, or if there is a little seal as I was in a hurry. The cases are not cracked, but just to be safe, I put some JB weld where the chain had hit. So what did I do wrong to cause it to leak?
