Does anyone know where the loader bypass adjustment is located on a Montana 4344?

Fallow the pressure line coming from the pump. It might come to a relief valve before it goes to the loader valve. The valve block in the picture doesn't seem to have a relief port/adjustment screw, which is usually a hex set screw with a locking nut on it.

I'll have to check for that, seems like this might be a nimco loader valve, and might be non-adjustable, not sure if that means it's set to whatever the system is or it's own setting though.

Is this it?

That is definitely a relief port, (the set screw and nut) the question is... where is it at in regards to the loader valve? is it before? if its after it will only provide relief for the 3 point...

Just loosen the nut and give the screw a half turn in (clockwise)... see if it does what you want... Anything more and you will want to put a pressure gauge on the system to prevent damage.
