Nice SU63-D impact, a good runner. It does move a little faster after the cleaning. Interesting how the bearing spring plays a big part of the impact's ability to move depending on the washers used.
You will like the test that comes at the end of my video I am getting ready to publish, Royal Coach failure. You see that SU63 with the bearing sleeve and nipple from the Royal Coach. WOW!
I had no idea a U63-D design existed. I thought they were all U61's. I have many U61's (some are Toro branded with the PJ tube). Although most of my 1/2" Toros are with a broken PJ tube (was a flaw in the design). I haven't seen it in the 260 design though. Yours runs good! I notice the difference in the sprinklers behavior after the bearing and nipple cleaning. These sprinklers don't move as quick as some of my U61 designs do. I remember even back then the U61 spoon drive brass impacts (The Alpha II) inside the Rise N Rain were quick reversers. A neighbor who moved a long time ago had these in his yard and even a full circle variant on a riser in the front yard (no trip mechanism or stops). But some of the Rise N Rains really moved in reverse. I think he had a pump to run all the popups too, since city water wasn't enough. I wonder if they are still at the house in the ground, with the grass overgrown over it. I'd like to know actually, Would be cool to actually go in the yard and try to find where they used to be. Thank you for sharing!
So there are two factors effecting the difference in the movement of the smaller design is the spoon is smaller and the newer washer design requiring the bearing spring slow those models down substantially. The full size U61 design with the newer washer design also require the spring above the bearing sleeve. The older design with the fiber style washer does not require the bearing spring and those move so much quicker and better. I like they way they scoot in reverse. I like the older design over the newer design requiring the bearing spring.
