Can't remove Hydo Relief Valve
 

I need to remove this hydro relief valve to get it repaired. However, I can't get a wrench in there as it's blocked. How can I get this removed?

Both sides of this combo wrench won't work. I also tried a "slim" one that wasn't as thick, but I still can't get it in there.

I'm able to get it on the other one just fine.

Socket? Been a couple of years since I was able to wrench on a cub, so I forget the size socket.

Or a deep offset wrench.

Use a regular box end wrench instead of the gear wrench.
I've never had an issue removing those.

I find it would probably be a lot easier to remove if you pulled the whole fender pan off, so you could get to it from behind without the charge pump relief getting in the way.

I would try to very,very lightly tap on the valve ,while turning with a closed end wrench.There may be just a bit of paint holding back.A good wire brushing,with a shot of air is a necessary thing.I some times use PB blaster over night on any thing that wants to be difficult.I personally don't use Gear Wrench to break fasteners loose.Thats just me.

Use a box wrench,--- if you ain't man enough to loosen it,
whack the wrench with a hammer, cussing the person that over tightened it.
Those valves have "O" rings that seal it, it ain't a pipe thread that you tighten it till it quits leaking.
if the fender pan is in the way, remove it, git er done ,they be grass to be cut.:biggrin2:

I'm not familiar with what you have going on. But, it sounds like your answer is a box end wrench, remove the belly pan and maybe penetrating juice.

Once in a while, you have to modify your tools to get the job done, by grinding, bending, welding or even making one.
