If I recall correctly, the Husqvarna 455 has a spur sprocket, where the drive gear is part of the clutch drum. That requires replacing the whole clutch drum when the spur sprocket is worn. If you are replacing the clutch drum anyway, consider replacing it with a drum which takes the floating rim sprocket. When those wear out, it's $4 part to replace, rather than the whole $20 clutch drum. The rim sprockets are easier on the bar and chain as well.
Not that if you do this, some saws also require changing the oiler drive gear as well. Try contacting https://www.baileysonline.com they can set you up with the needed parts to make the change, if you decide to go that way (and can also tell you if the oiler drive gear needs to be changed as well.)
