Determine the number of lines or hoses Knowing the number of lines or hoses is helpful in identifying the gear part number. Vehicles equipped with an assist gear all have 4 lines and many vehicles without an assist gear are equipped or ported for 4 lines. If your gear only has two ports on the valve housing this is a 2 line gear. If there is a third port with a steel plug or hydraulic line in the valve housing you have a 4 line gear. Look for the fourth port at the opposite end of the gear near the ID pad or in the ‘bowl’ of the gear near the output shaft. It is also helpful to know the location of the pressure, return, and auxiliary ports in the process of identifying a gear. There are four combinations of pressure and return port configurations.
