This is a good tip. Often things can only be put back together in a specific order. So, having a reference to the order disassembled is helpful so that you can then work backwards through them when re-assembling.

When I worked on my tractor, I found an online parts diagram and then grouped my parts in bags that matched the same categories / groupings as the online parts manual. Then, when I re-assembled, I could reference the parts manual diagram / pictures as well as my own pictures taken prior to disassembly.
