F.E. Myers Air Blast Orchard Sprayer Information

Well, I was able to grab the NOS units for $20 each. Not too bad! I am still going to explore the overseas units just for the sake of giving it a try.

NOS Piston cups showed up, look pretty good. They are pretty stiff. I am wondering a couple things. 1) Is this the way they come? Seven Gables has noted that they are tough to get in, I assume this maybe what I am going to encounter. 2) What is a good lubricant that can be used to assist and install these units? I have Murphy's tire mounting lube, Lubri-plate assembly lube, brake caliper grease, wheel bearing grease, lots of motor oils, graphite powder and spray and half a dozen different liquid soaps. I am leaning towards using tire lube to prevent any issues with unintentional degradation to the rubber cups.

Yeah stiff is how I remember them . I think you’re tire lube would probably work good. Best I can remember I just used whatever grease I had on hand, thin layer on both on the cups and cylinders. Pretty sure you’re going to want to soften them in some boiling water also.
One other thing, I always replaced the gaskets at each end of the ceramic cylinders whenever I replaced piston cups. This was on a John Bean pump, I assume the Myers would have similar.
Be nice if you’d post a picture of the NOS cups along side the cheap imports.
Also do the nos cups measure 2 3/16” OD like they claimed?

They are pretty darn stiff. Not sure if that is from age or that is how they are.

Asian units have yet to arrive, I anticipate a month or so.

A couple more questions to men with experience.

1) I really like the idea of using brass bodied diaphragm check valves. There isn't a lot of information that I can find on buying them or rebuilding old units. I found this eBay listing where they are offering TeeJet 975B brass body parts. I don't know if any of these parts make a single complete unit because I am unable to find any photos of a complete unit nor can I find a resource for rebuild parts. I can live with my inline strainer check valves for a season, but going forward, I would like to upgrade. I have PLASTIC diaphragm check valves on my FMC, but I don't want to take them off of that unit just in case I need it. Any thoughts?

Looks to me like those check valves parts are everything except the main body and the diaphragms.
Go to TeeJet website, they have pictures of the check valves that those parts go to. TeeJet also sells the little strainers that insert before each nozzle that have ball and spring checks built in.
What inline strainers do you have that have check valves? Pictures?
