It might look a bit tricky, but I wouldn't spend much time searching for a video. No disrespect to the guys who do or have done it for a living, especially when it comes to trying to track down a particular problem, but yours is more of what I would look at as long term maintenance, and I'm sure that you can do it. I have several old baking trays that I use for disassembling and reassembling such things, but a clean spot on a work bench works fine. As mentioned, the kit should have basic instructions, including measurements and gauges for the various adjustments. Keep an 8-1/2 x 11 pad and pencil and your smart phone or camera handy, so that you can sketch or snap reminders of how things came apart. Take your time and you'll do fine with it.
