Those are really close, I am just NOT ready to drop $30 a piece for 18 of them.......I also like bringing back some old things back from the dead. (As you guys already know). A question I do have is the replacement diaphragm. I see them in a variety of lbs. Is the lbs the PSI that the check valve closes? So if the replacement diaphragm says 10 pounds, that means it closes at 10 psi?

I used lots of T-jet products and yes, it closes at 10 PSI. Cutting off at 10 PSI cuts off the dripple that would happen if there wasn't a check valve and the pressure slowly drops to zero. It also, gets up to pressure faster since there is a residual 10 psi in the line.

Update: Weather in the area was in the upper 40's last night so I was able to install the new piston cups and assembly. Someone on here, I believe Seven Gables, mentioned boiling them to soften them up. Worked great. I used my old Coleman camping stove, an old pot and dropped them in. They 'boiled' for about 5 minutes and I put them into well lubricated sleeves coated with Murphy's Tire Lube. They went right in.
The new Asian made units have arrived and they are much larger. Probably about an 1/8" larger. They MIGHT fit if I put them in, but they will probably require more HP to get them to spin. Worst case and in a pinch, I could turn them down on a lathe.

Update: I was able to use the sprayer for my first oil dormancy spray this past weekend. Worked great. It took a little doing to get the nozzle rate dialed in. I had the best luck with TeeJet orifice discs D3 at waist height, D2 higher up. I had to take the Cone Jet nozzles out due to using a 100 nozzle strainers and them getting plugged up in short order. A 25 mesh and the disc orifice was better. There is a bronze 4x6 pre-pump filter, holes are about 1/16” in diameter. That lets a lot of fines through the system. I would like to add a 150 micron sock around the bronze mesh. Is that a “no-no”? I have a feeling that it will clear up over time, but I would like to catch it before it runs through the pump and the nozzles.

Pretty typical for the first spray with a older sprayer that’s sat for years to plug filters and nozzles. I think you’re best option is to just keep flushing water through the entire system with the nozzles removed.
