Wood Cookstove Cooking: Answer to a "Grate" Question
The gears of the grates do mesh in the middle, so it sounds like you need to replace the right grate bar. The part number for the grate bar is 527R. I assume that you also will need the grate cog, which is 529R. If I missed my guess and you need the left side, substitute an "L" for the "R" in the numbers above, and you're good to go.
