I was brand new to pools last season and to start things off my pump did not work. Taking it apart was definitely easy. I took the motor out and could have easily put in a new one. Once it was determined that the motor was shot though, I couldn't find a deal like you found, so I just bought a whole new pump.

When I was working on mine, I made a posting to this site and attached a couple of pictures of it taken apart. Here's the thread:
