I have a husqvarna 450 rancher and the clutch sprocket just lost a tooth. Saw is a 2011 and has about 50 cords through it. Serial number 4200876.

First, I am not 100% sure I am finding the right replacement part on the web. Can someone point me in the right direction? Seems I have fallen into the internet trap of finding conflicting info.

Second, should I replace any other parts of the clutch assemblage in the process?

Thanks to all.

Part number should be stamped on clutch drum. Probably part number 578097901. 577035301 is updated number.
 
You wanted pics.
Took it apart today. 7 tooth down to 4. Part # 5038730-03.
