As long as you are going into the pump you may want to consider replacing all the o-rings and seals. The flexible washer like piece that holds the weight retainer to the drive plate is especially prone to failure.

Hopefully you cleaned the outside of the pump well before removing from the tractor. There are a number of special tools listed but you should be able to get by without them. I use a hog pan with a couple of inches of stoddard solvent in it and put all the pieces in there as I remove them. Clean diesel will also work, just smells a bit more and is a little oilier. The only adjustment you will need to upset is the rod the the governor spring rides on. Crack the lock nut loose and the count the number of turns it takes to remove the rod. Write this down so you have it when you are reassembling the pump. All the other adjustments you should be able to leave alone. Take your time and take note of anything you are not completely sure of as you take it apart.

Keep everything clean and follow the manual and you should have no problem.
