I don't know of any webiste about what you're considering. No offense meant by this at all, but are you aware that this is a cheap ($58 at wallyworld) trimmer, and not generally worth repairing. It's meant to be a disposable unit good for only a few hours of run time? I'm all for fixing stuff and getting the full available use from a piece of equipment before trashing it, but I don't even put much effort into fixing low-end trimmers because once one thing goes bad, the rest is right behind it like a train wreck. I wind up spending more time and money on the thing, then toss it anyway.

However...this site is called Do It Yourself, and if that's what you choose to do, we can help.

Ok...as I recall, to remove the piston and rod you would remove the crankcase cover at the rear of the engine (4 screws in the plastic cover), remove the carb, muffler, and then the 2 screws holding the cylinder on. Slide the cylinder upwards and it will expose the piston. The rod just slips onto a short peg of a journal on the crankshaft.

I suppose the wrist pin is probably pressed in, holding the rod and piston together. Why would you want to remove the rod? What else of the block do you want apart? There are no parts of the block to be removed. You can take the crankshaft out of the block, and unbolt the coil if you wanted to, but that's about it. You have to take the other end of the engine cover off to do that.
