Farmall C251 part needed w pics

Any body have a source for this spring?

It's in the chain tensioner pictured. Part # 623 120 R91 The spring pictured is the good one. Part #PA2 080

I've found several "torsion springs" on the net but none combined like the original. The more I look the more confused I get. I don't know what inch pounds I need. If I can't get OEM I think I need 1 right and one left.

Any insight would be greatly appreciated.

Go by the wire diameter, coil diameter, and number of turns to estimate spring size needed. Larger wire and tighter coil makes it stiffer. Number of turns give it the travel. It's probably not real critical. If you have a local city with a spring manufacturer you might get them to make you one, but it looks a lot like a baler or rake pickup tooth with the tines cut off. Try a local farm supply store.
