now that everyone's been warned, you need to get another price, unless you want to send his kids to college. if he gave you a very high price, then take a look for yourself. you don't have much to lose. if you take anything apart, lay it all out in the same order that you took it apart, so that when you put it back together, you get it right. the manual should have a diagram showing where everything is. if you already gave it to him you should study the manual and learn about your machine. the mechanical part isn't so scary. sorry this had to happen to you.
