segmented sprockets question.

Hey guys. A question about the sprokets on my 8k. They seem easy to change. Can I do it myself. A guy also told me to have the pins turned on the rails after the sprokets put on. Im thinking thats a big job right there. Im just wanting to put the new sprockets on for now so it wont skip cause they are pretty wore and I hate having the track so tight.
