Actually you can crack it with trial and error. All you have to do is crack one letter at a time starting from the opposite end that the dial pulls out of and EVENTUALLY you will get it. And if you use actual words like OP did, all you have to do is be good at word puzzles because if you know a few of the final letters you can guess the whole word.
How do you get the numbers on the combination?
