To disassemble the bolt you need to remove it, and pull back on the cocking piece on the underside of the bolt, (its about 1/4" thick by 3/4" long and has a notch in it, it's at the rear of the bolt.) It pulls back prety hard, you'll need a tool of some sort, or use the edge of a table you don't mind dinging. With the cocking piece pulled back, unthread it from the bolt body, the firing pin will come with it. This is all I do to clean the bolt. Re-assembly is just the reverse, you'll see the little notch in the main bolt body that you stop in. The extractor I'm not sure about, other than I'm pretty sure it's peened in, and requires special tools to reassemble. Hope this helps.
