    Messed up front sprocket install need help

    Ok I put on a new sprocket and chain and did not install the sprocket correct. I only drive it a couple of miles and took the cover off for a different reason and noticed this.image.jpgimage.jpg

    The screw heads are ground almost off. I can slide the sprocket back and forth on the shaft.

    Is the keeper plate damaged? That's supposed to keep the sproket in place, although not in an exact position. Not a good situation. If the plate isn't damaged, could the small bolts have sheared off? I know the plate and sprocket have to stay together or the sprocket will 'wander'.

    The sprocket has to go all the way on the shaft. The lock ring must push on far enough so the tabs on it reach the grove where it will turn and lock the sprocket in place. When the sprocket is fully seated and the lock ring tabs are in the grove you can only get the screws lined up if the ring locks the sprocket in the correct position. I have no idea how you ever got the screws lined up in the sprocket holes without the lock ring being in the grove but it sure does look like that is what happened.

    It looks like the sprocket wasn't on far enough when you installed the keeper plate. The keeper plate goes in a small groove then you twist it to align the bolt holes. I bet the sprocket wandered outward and rubbed up against the seal and the keeper that holds the seal in place. For sure you need two new bolts to hold the keeper to the sprocket, and a new outer seal, and probably a new keeper plate that holds the outer seal in place.

    Post a picture of the inside of the left side cover -- the part where the output shaft goes into the left side cover. I bet it is chewed up.

    You didn't have the sprocket on all the way.
