This is a new Gear Pump Conversion Kit that converts 2+2 tractors from the axial piston style hydraulic pump to the older gear style pump. This kit does not include a new gear pump.
The price does include a $100 core charge for your old Axial piston pump. $100 will be refunded when I receive your Axial Piston pump.
If you need to operate a hydraulic motor you should use a flow control valve.
Instructions can be viewed here.
