Curiosity about your grapple setup: do you have a diverter where you push a button and control the grapple with the loader joystick or a power-beyond setup the enables simultaneous loader and grapple operation?
I have the power beyond from EA. You just push the button and operate you dont have to move the joystick at the same time.
Thanks, I wasnt able to open the attachment. Is it in the workshop manual, I bought one with the tractor.
Hmm, the attachment is a pdf. Doesn't double-clicking link give you the option to "open with" or "save as"? Should be able to open it with Adobe Reader, among other applications. In any event, it is section 6-27 in the pdf version of the manual that I have. I'm assuming that corresponds to the hard copy you have. Look under chapter 6 - HST.
I was going to ask the same thing about the valve for the grapple, if it was for sure a diverter or 3rd function. Seeing that it is a 3rd function type And you said the grapple opened on its own is telling me the valve for some reason is bypassing and dead heading your hydraulics causing the oil to over heat and starving part of the system for oil.In that case, I suspect your diverter valve is dead-heading the hydraulic flow, which loads down the engine and froths the hydro oil as it is forced through the relief valve. Does your 3-point still work (I'm guessing no)? Something you did when you replaced the O-ring caused this, I think. I'm not familiar with your valve but maybe that plug was some kind of adjustment and you "adjusted" so the valve block the flow. This is just guesswork on my part but maybe someone like JJ (who actually understands hydraulics) can elaborate.
