- This was a group of 5 different sprinklers that I picked up locally in this box. I pointed out to the man each of the sprinklers and what they were by name or title. I very quickly point out to you here the zinc sprinklers and how they do not hold up and wear out much quicker than a brass or plastic sprinkler. I hope you enjoy the explanation of the U61D, SU63, and the U61A model. They cut back on the brass used in the U61D from the U61 A, and then cut back further in making a mini model of the U61 design, as I point out the differences. I wanted to point out the reason why I lighten the spring setting so that the arm just meets the body. The sprinkler works better and smoother in the long run. I hope the SU61DP model shows that with the spring lighter in tightness. I was pleased with the results.

Nice Haul Randy !
Sweet to find some local treasures! I’m impressed that you know the details of how even some of the lower end sprinklers wear. You have quite a breadth of practical knowledge of these.
Thank you for the compliments and most importantly watching and sharing your knowledge as you do so well.
Nice additions to your sprinkler collection. The SU61DP runs really well.
I have a video coming soon with the SU63 spoon version that I have on the stand now. It is not fast, but very steady. I probably will disassemble it and clean the bearing and nipple parts, and try it without the bearing spring.
I think that first one is a Naan irrigation zinc model. I have one too that i rescued from a trash picked tripod (hose connection was broke off), so i removed the head, and tested it on a hose type base. It worked well. I have a video of it on my channel. I think Naan Irrigation joined up with Jain, so now they're NDJ Irrigation (Naan Dan Jain). They're plastic impacts resemble the ones you sent me, and I have a NDJ branded plastic impact myself. Interesting enough it has a red sleeve over the trip notch on the arm just like Gilmour did with their brass/zinc models. I also see a very in good condition U61 with the PJ tube, it looks brand new and never used! I believe (correct if wrong) the DP means Deflector and P means PJ tube? Great score. I love the 25-PJ-DA RB also, those bring back memories as a kid of a house that had a ton of the 25-PJ-DA models (deflector) on risers for their underground system. I used to walk there every day and just watch them operate, hearing them all run at once was quite the sound! just a reminder of the days of summer!
You are correct about the Naan model, this one was made in Israel. The Naan name seems still quite a bit in use. I did not say much about the zinc model, mainly from what I am finding out is they do not last or hold up very well, and will show that in another video. They will work and get the job done, but are of poor design and do not hold up very well. The wear is pretty extreme, I have a whole bunch that are really nothing more than parts because of the wear, but make great experimental sprinklers.
I pulled our a few of my other U61 designs, because of the differences in them and of course my U61A which I will put on the stand as soon as I get the coupler off. There is a full size U61 and the mini as I call the smaller modified U61 design, as I showed in the comparison.
Interesting design differences between the U61D and U63. I never noticed it myself, but the U63 is a mini, it def is smaller. I wonder why they designed it like that. Unless its to make it work in lower pressures. Your P4-PJ reminded me,. I think the P4-PJ-TNT was inside the 15105C. That had the metal diffuser screw and trip collars i believe. It might also have the metal TNT bearing instead of the plastic one thats on the P5-PJ. the TNT bearing was for long life between service. Heavier duty, like my 85HD-TNT. Those had a heavier longer lasting design with locking trip collars and the removeable drive spoon. That 25PJ reminds me of back when I had a few of them myself and a house down the road that had them on risers for the front underground system zone. I love the sound that tube makes, you can definitley tell when a sprinkler has it. Question, on your U61 and U63 those nozzles look pretty big, like 1/4" or bigger. Those i take it won't run off the hose right? I remember their plastic impacts having the hooks for the spring. I believe that's to make the tension a bit more loose to work in low pressure situations. My Maxi paw even has the same setup on its arm. You can take part of the spring off of it relieving some tension which makes the arm work when the pressure is low. A nice design feature in case you might want to run multiples off a hose. Your U61DP works great! and doing a great job keeping the sidesplash in line with the stream. It stinks that the design of the PJ tube was flawed and so many U61P designs broke the tube off. I have 3 toros that are missing their tubes as well.
This P4 model is the basic plastic model that was sold on a card in the store. The older P4-P5 design had stainless stops on the plastic bearing sleeve. I have the old design and the newer design. First the old design had a separate nipple that could be removed or unscrewed. The newer models, have the nipple attached to the body and cannot be removed or taken apart without damaging the potential of the operation. The plastic bearing sleeve went to the plastic stops as well.
The smaller U61 and the SU63 design are the same mini size. It is like the U61 design was downsized. The older full size U61 design used the older fibrous washer and did not need a spring between the bearing sleeve and the body. When I ran the SU63 with the fibrous washer and without that spring it works great and even better as will seen at the end of my newest video. Wait for it, Royal Coach, failure.
The hook you are talking about is a new idea on many smaller sprinklers, which is much like what I am trying to accomplish with the loosening of the spring. I like that the design of those arms are designed so that you can hook the spring at a tighter or looser position. I personally like the looser position. Another experiment to arrive soon.
The nozzle on those two may have been 1/4, but not sure as I thought they were a little smaller. I will have to do some checking.
The Blackbird you have out of the box looks similar to a model i had back when i started into sprinklers again. Is that a P2-PJ? I remember the old models had the metal trip collars and diffuser pin, some even had the brass spoon arm as well. I should try to find my blackbird and make a video on it (not running, maybe i could).
The plastic one is a P4-PJ model. I think these were done this way so they could be put into the bigger canister for ground level systems. It does have the diffuser built in. The Rain Bird model 25-PJ was in pretty good condition.
I think a tap or something may get it to turn enough to get it out. But Other than that I'd be afraid of damaging the threads unless you do it very slowly with a small size tap. I'm thinking maybe Bill might have some insight on getting that out, but you may be right, it might work as is . Kinda like my Melnor plastic impact that i bouight NOS. lol. Or an easy out ( i think thats what there called, they're used in the auto business to get stubborn bolts out (or nuts). Was that a plastic nozzle?
An easy out is a good idea. It is plastic so it is not like stuck in there so tight it would be a real issue.
