This sprocket has been discontinued according to Cat. Anyone aware of an aftermarket worth using? Cat option is a segment sprocket that runs about 1300 dollars US with hardware. Original was 516.00.
Search the salvage yards for the segmented sprockets is what my plan of attach would be or you may still be able to get a new sprocket ring to weld on
Here are a few other Part Numbers you can use for searching. 6S-8270 is replaced by (in order) 5G-4050, 5G-6082, & 8Y-0622. These are all one-piece complete sprockets. Then we move to the replacement weld-on one piece sprocket rim for any of the above. See SEHS7274 attached. It is hard to read the table but the Rim Part number for a 931 appears to be 7T-8987.
Aftermarket one here on eBay .
