On a hunch that that Johnson built the B219 loader for Kubota, I ordered the cylinder rebuild kits for the B219 from my local Kubota dealer. Turns out the seals are exactly the same size as those on my Johnson 10tc loader.
My question: The main rod seal gets sandwiched between 2 rubber washers. These rubber washers are flat on one side and concave on the other. Does the flat part of the washer go toward or away from the o-ring?
This is my first hydraulic cylinder rebuild, and despite having rebuilt many pneumatic cylinders I have never seen these thin washers with the one side concave before. Even the washers in the cylinders I took apart to not have that concave on them.
If anyone has any experience in this I could use a little help. Thanks.
