There may be, but an exact disassembly is probably going to depend on what specific lock you have. You're better off watching something like
this and then trying to identify the parts in your lock that correspond to parts in the video. If you really understand how your lock works, it should be relatively clear how to remove pins. And understanding how your lock works is really fundamental to being able to pick it.
This isn't actually as difficult as it sounds. I disassembled my first lock on my first try without instructions (or even tools). Two mistakes to avoid, though:
1. If all you want is to remove pin stacks, it's not necessary to remove the plug for any of the simpler locks I've seen. You can remove stacks this way, but it's going to be difficult to keep in the one(s) you want, and re-pinning will be even more difficult. It's much easier to remove the pin stacks from the spring side if you can.
2. Usually there's something over the spring side of the pin stacks holding them in. You'll probably want to remove this, but when you do, be careful! The springs are under pressure and will jump out. Either slide something (a finger, maybe) over the spring as you slide the cover off, or be prepared to catch the springs in a container of some sort. You don't want to be hunting around on the floor for tiny springs.
