Do you have a relief valve on your hyd block?
Not sure what hydraulic block you are referring to? The only one on the B3200 is the loader valve which is integral with the tractor. All hydraulic flow goes through this valve.
Do you have a relief valve on your hyd block?
That is correct. The relief in the loader does the whole system except for the 3pt which has it's own.I looked in the owners manual and there is no hydraulic block when there is a loader valve built into the tractor.
If there isnt a loader valve then with the hydro block, it says no relief valave in the block.
So JJ with what you are saying does the backhoe have a way to adjust the pressure relief. I have three owners manuals that came with the tractor...one for the tractor, one for the loader and one for the backhoe. The specs in the tractor manual and loader manual call for pressure relief of 2205psi. No specs on what the pump actually produces. The backhoe manual has no specs for pressure relief...so does this mean it is controlled by the power beyond at the loader valve?

JJ,
I am 100% positive that the loader valve is part of the standard equipment of the b3300su. It is right below the heel of my right foot. I am thinking the loader valve is the main relief ...in the manuals its the only one with specs.
I will take a picture of the loader valve and backhoe valve this weekend.
