Stihl 015 Oil Pump Drive Sprocket 1/4 Chain

thingiverse

The 015 chainsaw from Stihl no longer receives support, meaning if you need a fresh drive sprocket for your oil pump, you will have to create one yourself. The following is a stock image of the 1/4" chain sprocket as found on the original equipment. To switch to a new saw with a readily available chain in stores, simply print the 3/8 version and replace the bar with a newer one along with a corresponding sprocket. Let's keep those tools well-oiled!
