I have a 042av that needs a new spur sprocket. It’s the early 2-piece drum/sprocket. There was a thread I found that someone had mentioned there was a retrofit for a rim sprocket setup. Does anyone know where/if I can find one - or if there are any of the spur parts available anymore? I saw Chainsawr had the whole clutch/drum/spur available for $40, but all I need is the spur.image.jpg image.jpg

Is that the same as an 038 drum? If so rim set ups arr still available from Oregon.
Not sure - Stihls are less familiar to me. Have a part number handy? If not, I can try to look it up.

You may want to get the complete assembly as you mentioned. That oil pump drive gear is looking worn badly.
I’ll have to look more closely at the gear. It didn’t seem too bad at first glance, just a bit discolored.
