everything came in the box. looks very good quality. if you look up a video on how to install it on your chainsaw it really helps if you've never done it before. I put everything on and it worked great. took about 30 minutes to install. highly recommend it. only thing missing from the package might be a little Grease for the bearing.

Product does not fit MS250. Looks like a fine replacement for any saw it does for but wrong number of teeth on gear and too large oil work gear for the 250.

I bought this hoping to avoid the high name brand prices. Unfortunately the drum is not round. The deformity is easily seen when I spin it by hand with the side cover off. When the chain is installed, the tension can not be adjusted correctly because it becomes tighter and then looser as the drum turns. The price was good, but the quality is so low that I won’t be able to safely use the saw and will have to order another better part. I’m going to try an Oregon clutch drum. Better price than Stihl, and the quality is excellent. Also, the e-clip included is much to small to be used. I wound up buying one at the Stihl dealer to be able to try to use this drum, and the whole experience has been a waste of time. Now I have to deal with the return process.
