ASR-33 Restoration

I recently acquired three ASR-33 teletypes in various conditions. It looks like two of them are complete and one has been scavenged slightly for parts, but appears to be mostly there. I would like to restore at least one and hopefully two of them. I have the technical manual, which I have started reading. I've also googled and found various sites with info, including previous discussions here on CCTALK. Does anyone have any pointers or good reference sites on testing and bringing one of these things back to life? I want to start at ground zero. One of the TTYs seems to power up fine and the motors run, but I can't get the keyboard to type in local mode. The keys don't press down all the way. The shipping bolt was not in place when these were shipped, and I know they were picked up and tilted and moved around, so things inside may be out of alignment. All three have the phone dialer options installed on the right hand side. I don't intend to use the phone dialers, but it would be interesting to have one cleaned up for show. I have another good ASR-33 working and hooked up to my PDP-11/40 on a 20mA DZ11 connection. Any advice is appreciated. In the meantime, I am going to continue surfing for information and reading the technical manual. Thanks, Ashley
