John Deere 2120 Pressure Relief Valve Location

So just plug it into the quick connect fitting and move the SCV to dead head the pump?

Can't dead head the pump. It's a variable stoke closed Center eight piston radial pump.

May I ask you to clarify your statement?

bigblock76 can plug a 3000 # gauge in rear breakaway coupler and hyd oil will be dead headed into gauge which will be stand-by pressure..

The pump can be dead headed , won't burst a component and doesn't need a relief valve. A positive displacement fixed flow pump if dead headed will stall or break something.

I thought you stated earlier it couldn't be dead headed????? I hope you make better decisions at your Nuclear JOB !!!!

#19 2nd photo is the adjustment screw for SC valve

Ok thanks. Looks like that should be easily accessible from underneath the tractor. Can it be done with the engine running or best when its off?

Yes it can be adjusted with engine running.

My 2120 JD has a power steering issue. Power steering will stop working after about 30 minutes. Let tractor sit for about 5 minutes and it starts working again for a while. Any suggestions on causes and solutions? Thanks
