I've had my backhoe (BL4690) on an off my B2910 more times than I can remember...
Honestly can't imagine how I could put it on different than it came off!
Unless you did more than remove the backhoe by taking the pins out of the top link and lower arms, it is probably impossible that you could have put it on different than the way it was when it came off. At least that is the way it seems to me.
Now whether the dealer did it right the first time is another story.
Attached is a photo of how my B2910 and backhoe looked on delivery day, summer of 2002... /forums/images/graemlins/shocked.gif This shot may give some insight as to what it might be supposed to look like. I just assumed it was the way it should be... /forums/images/graemlins/tongue.gif Seems to work well this way...so it is probably right... /forums/images/graemlins/smile.gif
