Thetford style 2 water valve wore out. Got a replacement kit. Watched a few videos. It was a piece of work but I got there. All back together and installed. it works. But my flushing arm keeps sliding off the back post that operates the water intake (which was the part I replaced). I took the toilet off, so I worked on that flush arm pretty hard. Used a rubber mallet to bang it into place. It seems to bang into place nice and flush but it twists when I step on it. I can pop it back into place but what a pain. Hoping somebody might have some advice for me.

Edit: now wondering if this was the original problem and I didn't know enough to check for it when I dismantled it.
