I need to buy a 36 inch bar and chain for my trusty old Stihl 031 for basically a one job use (a 55 inch diameter Red Oak truck about 8 ft high - maybe 2-3 hrs of use but I want it to work and the prices are about the same at the web vendor -
an 031 is going to have a hard time pulling a 36 inch bar and chain. if you buy 3/8, bar and chain, .063 guageit will be maybe 115 drive links. Just cause you can buy it and hookit up doesn't mean that it will work well. Better do your homework and run a 28 and come in from it like a pro.
Yep, 36" is -way- too much bar for that saw. It is going to cut very slowly if at all in that tree. The pros consider a 20" about right and
24" about max on a 031. I run ms310 (same as 031) with 20", would have bought it with 24" but already had a 041 with 24".Harry k.

Not realy sure what your question is, but the need to replace the sprocket would depend upon its condition. Generally I have replaced just bars and chains.

If the chain size is being changed then the sprocket as well. Those sprockets stand up pretty good. I too have rarely needed to change them.
