Just refer top them as sprockets (w/ teeth), it's easier.(had me confused for a little bit) I used to work at a sprocket shop and never heard of anything about using odd numbered sprockets with the double pitch. We would just cut another 2060 or whatever they brought in, or we'd replace them with the standard sprocket on both ends and then they'd use a regular pitch chain.

I can see why a guy would want to use an odd numbered sprocket if mix'n and match'n for wear purposes, but it woun' affect the shain wanting to climb. That's just a stretched chain that wears on the outside of the tooth instead of the root diameter where it's supposed to ride.

In the even a chain is stretched and is allowed to wear the sprockets up on top, you gotta replace the whole works because it wears the sprockets so that a new chain would ride up on them, and the new chain will soon be stretched just like the old one. If the sprocket is worn more on the bottom, you can ussually get away with just replacing the chain once, then chances are it'll be too far gone the next time. Since I've worked there, I've replaced many a sprockets on our farm with new ones, especially the AGCO equipment (Mainly New Idea) with new ones form work because we made them for AGCO, for both new machines in production and for the parts counter support on older ones.

I no longer work there, but I'm still freinds with the owners and stop in now & then for a new sprocket or 2.
