Hagen Brothers farms,Goodrich ND | Are they leaking between the cartridge and tip ,or cartridge and scv body ? I have the ISO conversion cartridges in my 4020 and have had 0 leaks since I installed them with standard O rings between scv body and the ISO cartridges. Nothing has bent,broken or leaked on the ISO conversion cartridges in 10 + years. I never try to couple/uncouple them with high pressure in the tips/impliment cylinder,maybe thats why they have been trouble free. One trick that I discovered a couple years ago is to replace the round O rings that seal the tip in the cartridge with square "quad rings" from my CNH dealer. They will seal a slightly worn/damaged tip/cartridge body where a stock O ring will not. They also do not seen to wear out like a round O ring which has to extrude into a square gap to seal,while a quad ring does not. I have been replacing the "inner " O rings on several different brand tractors that use Pioneer/ISO tips with the quad rings. In all cases,a coupler that leaked immediatly or shortly with an O ring,has not leaked with a quad ring in a couple of years. Might be worth a look. |
