Hi I have worked on 165 steering and can only find 3165 on agco parts page no 2165. I am guessing you have a steering box with no hyd connections to it and a pump mounted on the timing case or belt driven from the engine pulleys.
This steering box is then connected to an arm that runs down the side of the motor to the front of the tractor. inside the front grill there is a steering ram and 2 big cast iron arms. the lower arm is fixed to a shaft that drops down to through the front casting to the track bars and front steering. The top arm has the steering link attached from the steering wheel. then there is a large slot headed adjusting screw with lock nut on the top arm, that links the top part to the bottom arm, then a short smaller linkage that connects to the control spool on the cylinder.
when you move the wheel there should be a little play between the top arm and the bottom. that play then moves the small linkage to the control spool and activates the cylinder. if you got pump pressure and good cylinder/control valve. my guess is either that top arm ajustment is to tight so moving the wheel doesn't activate the spool linkage soon enough. the spool linkage is set wrong, a combination of both or the linkages/ or that adjusting pin are worn and it doesn't sense the free movement. you can probably still steer the tractor just through the steering box but it's real heavy. I know mine needed re bushing/ pins replacing on all that top linkage to get it working, and it was a fiddle of a job to set it right so it worked. Hope this might help you a little Regards Robert

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
