CONNECTOR 0094440 - Caterpillar

Personal injury or death can result from machine articulation or movement.Machine frames can move and a person can be crushed.Connect the steering frame lock link between the front and rear frames before working on machine.
Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.

(1) This sensor must be purchased separately. The sensor is not included in the 198-4240 Digital Pressure Indicator Gp
(2) This sensor can only be used on large diameter pressure taps like 6V-3965 Fitting.Test Preparation
Refer to Testing and Adjusting, "Machine Preparation for Troubleshooting".Refer to Testing and Adjusting, "System Pressure Release".Relief Valve (Steering Cylinder) - Test
Install the steering frame lock into the LOCKED position, as shown.

(4) Adjustment screw
Remove the steering cylinder crossover relief valve (2). The steering cylinder crossover relief valve is located in the steering control valve. The steering control valve is located on the left side of the machine. The steering cylinder crossover relief valve needs to be bench tested. Loosen locknut (1) and remove the valve.
The pressure of the relief valve should be 29100 700 kPa (4220 100 psi). Adjust the valve pressure, if necessary. Loosen locknut (3). Turn adjustment screw (4) counterclockwise in order to lower the pressure of the valve. Turn adjustment screw (4) clockwise in order to increase the pressure of the valve. Hold adjustment screw in place and tighten locknut (3) after the correct pressure is reached. The valve is faulty if the adjustment screw does not affect the pressure. Replace the valve.
Install the relief valve into the steering control valve. The valve should be installed with a torque of 60 7 N m (44 5 lb ft).
