The new cylinders do not require trim files and are a direct replacement for existing cylinders.

For a complete list of materials and the correct procedure that is needed to install the new steering cylinders, refer to Special Instruction, REHS9823, "Instructions For Installing Steering Cylinders With Position Sensors On Certain Motor Graders".

The special instructions can be found on the Caterpillar Service Information System (SIS) and through the normal literature distribution system at your local Cat dealer.
