I had mine for 10 years, a full set of 19 of them, and I replaced all of them for this reason. You will get a full set of nozzles with each head (buy the full PGP, not just the innards), instructions on how to pre-adjust it, etc. Yes, you will have to dig out around each head you are replacing to unscrew it and put the new one in, just be prepared to get "wet" when you are doing final arc and distance adjustments in open valve zones. I thought it was easy to do, but I did get wet and dirty.
I recommend that you examine the elbow joint next to the head when you remove a head, because this is where PVC piping can be broken easily. You may need to replace some piping in this area too. The telltale signs of a piping leak are mushy spots in the grass near a head and unusually high water bills.
One other word of caution is to make sure a rock or other debris does not get down into the pipe connecting to the new head or it will clog the head. After doing a couple of head replacements, it will become second nature for you.
Click on the 'Need Help, Product Manuals' on the Sprinkler Warehouse web page. It's in a blue box on the left side about 1/3 the way down the page. The Product Manual page should come up. Click on 'Hunter Rotors'. On the page that comes up you should see PGP Series. Click on 'Product Info under PGP Series and a black and white PDF Rotor PDF brochure should come up. Page 8 shows the performance for each of the nozzles you received.
There are 2 ways to adjust the right side, the last one is easier since it doesn't require you to "dig up" the unit. You can see all information about adjusting your PGP-ADJ at the Hunter website and I also copied the section pertinent to your question below:
Aligning the Right (Fixed) Side of Arc
If the right side of the arc is not properly aligned, the results may be a wet walkway or a dry turf area. The right side arc can easily be realigned. One way to realign the right stop is to turn the whole sprinkler body assembly and the fitting below it, left or right to the desired position. This may require temporary removal of the soil around the sprinkler to allow you to grip the sprinkler housing.
Another way to reset the right arc is to unscrew the body cap counterclockwise and remove the internal assembly from the body. Once removed, rotate the nozzle turret to the right stop, screw the internal assembly back into the body with the nozzle aligned to the right side of the area you want irrigated. At this point you have realigned the right arc stop, and you can adjust the left arc to an appropriate setting.
Note: It is not necessary to dig up and remove the whole sprinkler to realign the right arc.
These are only made for 3/4" inch risers but you can buy 3/4" X 1/2" combo risers. They will allow you to put the 1/2" end of the riser in your fitting underground and the 3/4" end of the riser in the Hunter head. This works great without having to change your fitting. These combo risers are cut-off risers so that you can adjust for height. They cost around $1. Hope this answer helps you. I have been doing underground irrigation for about 20 years and am extremely familiar with the parts.
Check with Sprinkler Warehouse you may be able to get them pre-installed.
While holding the nozzle turret at the right stop, turn the wrench counterclockwise. ...
Adjust to any arc between 40° and 360°.
