Rob, you posted this in the wrong place. The Annie is not all that hard to get apart but it's probably my least favorite to put back together. I think Greg's website has some info on it, also George Schreyer's. Taking it apart won't damage it. There are only I think 6 screws altogether. The annoying part for me has always been getting the airtanks back on
I installed DCC in mine, it was a matter of tracing all the wires. Not that hard.
