Combines R72 rotor coupler

We replaced ours when we had the rotor out to replace cylinder bars. Based on that I do not think I could replace with rotor in.

I have changed the hose with cylinder in the machine. It is not easy, but it beats taking the rotor out. If you put in a new one I reccomend you make it out of hydraulic hose, they last a lot longer. Sometimes the factory ones are made out of plastic and won't last as long.Hope this helps.
