The manual calls for Loctite 243 to be used, however, I was unable to find 243. I found 242 and I also have some 245, but no 243.
I would strongly recommend that you replace the CS sprocket bolt and it's spring washer when replacing the CS sprocket - consider it a consumable part. Although you might get away with reusing them, for the price it is not worth the risk. They are sold together:
CS sprocket bolt and spring washer P/N 590.33.034.044 $4.25
