Cleaning TK-50 Drives

I've got some TK-50 drives that I want to use a couple of in my MicroVAX II, they are all filthy, with big dustbunnies crawling out of them. I've picked up some of the proper foam swabs for cleaning tape drives, and a bottle of "Radio Shack Professional Tape Head Cleaner Fluid". I took the worst one tonite and striped it down, gave it a good cleaning, blew it out good, got it nice and spick and span. I've got it put back together now, and it _looks_ great. My question is, was this a good idea? I started thinking about this when I went and put the thing that looks like it has two magnets back in from of the tape drive head. By taking this apart like that have I messed up the drive alignment or anything? Are there any particular gottcha's that I need to be aware of. I'm already aware of how the tape leader needs to be attached and what to do if it gets sucked into a drive (had a tech show me on a DLT4000 drive a few months ago). Of course my plan is to install it tomorrow night, and give it a try. It's called I really want to get a good backup of this machine prior to starting to play with it (I know nothing about VMS, but have the System Manager, and User's manuals). Zane | Zane H.
