STEERING SYSTEM
POWER CYLINDER
ID and SIZE CHARTS
The Hydraulic Power Cylinders were manufactured by Bendix Corp. and used on the power-assisted systems. The cylinders mount to the centerlink and pull or push against a frame mounted bracket to force the centerlink back and forth. All power cylinders had two hoses coming from the Control Valve to receive and return pressurized fluid.
Each factory installed Power Cylinder has a Bendix ID code and a manufacturing date code stamped into the main body, located near the end closest to the centerlink mounting stud. These codes can help determine the original application of the cylinder and the year it was installed.
The first cylinder shows the Bendix ID code which is a 6-digit number that identified the model and year range of the car it was originally used on. The code for this cylinder is 128533, which indicated that the cylinder was originally used on 1966 Fairlanes. See the chart below for cylinder code details.

The second cylinder shows the date code which identifies the day the cylinder was assembled. In this case, the code is
6E16B. See the Date Code page section for more details on date coding.

Since the model code is for a 1966 Fairlane, the date code indicated a
1966 year (6E16B), and May (6E16B), and the 16th of that month (6E16B). The B at the end of the code indicates the shift during which the cylinder was made.

The last cylinder shows the Bendix script stamped into the cylinder body.
