Great video. Sold a bunch of the Royal Coach impacts in the period after they bought Buckner in the early 1980’s. Mostly 3/4” and up, but some of these smaller guys, too. They weren’t as rugged as the larger impacts The number that starts with a 5 is a part number. These 1/2” models weren’t as rugged as the larger impacts they made. Very good explanation about the washer. I always thought the back end of the lever looked odd on these, being cut off so abruptly. In the larger sizes Royal Coach let that lever hang a long way off the back. Appreciate your sharing this relatively short-lived brand.
If you did not know by the printed designation, you would not know it is not a Rain Bird model which it does look like with the cut off arm. This much like what I did back in the 60's to get more of the weight of the arm to hit the front of the sprinkler, but this was on the original Blackbird that had a brass arm. It was well balanced, and it was necessary to make that modification to improve the operation. There is another issue with this Royal Coach model is that it hits the front of the sprinkler on the nozzle, which wears out the bottom of the spoon area, one of the problems with the one I have even though it looks pretty new. I also discovered after the fact that this sprinkler has a stream straighter/restrictor and I have already removed it and will make another test with that modification. Thank you for watching the video, I hope you got to see the bonus at the end and the great result.
Interesting results that the SU63-D works good with the Royal Coach bearing. The Royal Coach may only operate properly with the tighter spring position.
I have noticed over the years that most every sprinkler that I have adjusted the spring so that the arm lightly hits the body, the whole operation of the sprinkler works so much better. I test the arm carefully to make sure it is not too light. If I had double the pressure of my house water flow, it might not need to be quite as light. I like the timing much better with a slower moving forward motion arm.
Nice experiment! I have had issues with some impacts sticking because of high pressure. They literally would go forward and then trip reverse and just sit there trying tto reverse but just stayin in one spot. I turned down the output on the spiqot and it starts working again. I guess proper mainteance is required to keep these brass impacts going! Same with the big guns! Gotta keep bearings and gaskets and seals serviced otherwise youll have one that wont move or will work but leaks all over the place. I have a few older impacts that leak from the bearing, they need rebuilt.
For me that is an easy fix with an o-ring which I have done in the past and worked well. I would put the o-ring at the bottom of the nipple, below the other washers. It surprised me how well it worked.
Randy, I could not see what you are doing when you use your tools. Your hands would move from the camera and all I could see was your work bench. I hate that we are missing what you are doing when using your tools.
Thank you for your comment, and I agree with you. I am trying to keep everything close up and that makes it harder to keep everything in the frame. I will keep that in mind as I work on my next videos. I even try to cut out when I am not talking as I want the video to be smooth and interesting. Again thank you.
