If relief valve is bad on my New Holland 7308 loader what would it do to loader?How would you know if relief valve is bad?:confused2:

See your other thread.......

We’ve been trying to help but your last post said you didn’t want to buy a pressure gauge and were taking it to the dealer.

Invest $15 in a pressure gauge as it is the only way to know if the relief valve is OK.

You can use your own quick coupler male fitting from any hose for the loader. You will need an adapter from the gauge's 1/4" thread to your coupler size.

Remove a line from the loader, plug in the gauge, run at full speed and send pressure to your new gauge for a few seconds only.

Compare reading to spec's.

The system relief valve limits the maximum pressure in the pressure line by relieving oil from pressure to tank. If the relief will not allow the system to build pressure The loader would not lift a load. It Would have no effect on loader or bucket drifting

That’s the “opens too soon” scenario.
Conversely, if it “opens too late”, or not at all, something either blows up or stalls.

I have had a guage but could not find qd to connect it.It also acts weird.When i move joystick to the right it curls the bucket.If i move it all the way to the right it uncurls the bucket.Boom also comes down fast and rough but boom does stay up unless i move stick forward or backwards

A failed relief would not cause any of those problems

Thanks for the help on that.Relief valve is out of the question.:thumbsup:
