Good explanations of all the variables you adjusted. I ended up changing a bunch of these out on a large nursery project in the very early 90’s before they were two years old. I think you point out the weaknesses of the sprinkler really well. Royal Coach, and then Royal Coach / Buckner (which just sold the Royal Coach products with the Buckner brand added to them) seemed to put a lot more effort into their 3/4” to 1.25” impacts than these guys. Great video! I appreciate your detailed explanations of what you’re observing in these sprinklers.
thank you. I am working on the possibility of one more try and test to see what other changes I have made to get this to work better. I already noticed a design flaw in the arm spoon and so I already made a adjustment to see if I can get it to work better. I wanted to take the arm out and replace it with a Rain Bird arm and that is going to be a big challenge removing the fulcrum pin. I also put it in a cleaning bath. I know I now have my teeth marks from my tools all over the unit now, but I want success over beauty at this point. Again thank you for watching and the compliments.
Interesting experiment. With the spring adjustment a little tighter, it's a little faster and does still fully operate.
