Step-By-Step Guide To Calibrating Your Caterpillar Hydraulic Equipment

It is necessary to understand the fundamentals of hydraulic systems before going into the role and significance of the Caterpillar hydraulic system and the intricacies of CAT hydraulic system calibration. It involves having a thorough knowledge of the concepts of a hydraulic system such as flow, control, and pressure that contribute to the smooth and efficient operation of hydraulic systems.

By going through the fundamentals first, you can gain insights into how hydraulic pumps generate power. If you check on the various CAT hydraulic systems such as CAT skid steer high flow hydraulics or CAT excavator slow hydraulics, you will find that there are different hydraulic pumps for various Caterpillar equipment. These include gear pumps, vane pumps, and piston pumps that are optimized for a range of performance characteristics and diverse applications.

Now, how do CAT hydraulic systems work? Hydraulic systems are driven by fluid power through various pumps that serve as the primary component. These systems generate and transmit power through pressurized fluid which is typically hydraulic fluid or oil. The main purpose of these hydraulic pumps is to convert mechanical power into hydraulic power.

Hydraulic pumps create flow and pressure by drawing in fluid from a reservoir and forcing it into a hydraulic circuit. In Caterpillar equipment, this pressurized fluid is then used in various equipment to operate cylinders, motors, and other hydraulic devices.

What Is CAT Hydraulic System Calibration And Why It Is A Critical Function

We have seen the various aspects of CAT hydraulic systems but unless they work to match your needs, you will not get the maximum performance out of it. One of the ways to do so is to use the Jaltest CAT equipment maintenance software for CAT hydraulic system calibration. Now, all CAT equipment hydraulic systems have factory settings that are set to meet operations in a standardized setting.

Now, suppose your project is in more challenging conditions. In this case, you must carry out specialized CAT construction equipment hydraulic system calibration on-premises with highly effective software such as Jaltest to get the maximum performance from your equipment.

To explain what CAT hydraulic system calibration is, let us go with an example of Caterpillar excavator hydraulic calibration.

To carry out excavator hydraulic calibration of your Caterpillar equipment, it is necessary to adjust the settings and parameters in a Caterpillar excavator’s hydraulic system to ensure peak performance. This requires setting values like flow rate, pressure, and control response. For this use our Jaltest CAT excavator hydraulic system troubleshooting software to tweak and modify the functions of the system and maintain high operating efficiency regardless of the conditions.

Fault Codes and The Paccar Engine Diagnostic Tool

Let us go now into the various aspects of fault codes and how the Jaltest Paccar diagnostic software clears them so that your vehicle is back on the job at the earliest.

As in all modern vehicles, Paccar trucks and engines have an onboard computer called the Electronic Control Unit (ECU). Whenever a malfunction occurs, it is displayed on the screen of the ECU in an alpha-numeric format. The ECU is located below the dashboard on the driver’s side and sends out a warning when a fault code is detected.

You have to then connect the Paccar diagnostic software laptop to the onboard computer to know the details of the problem. You will be guided through the various aspects of the fault including repairs and replacement of components if required until your engine is running smoothly again.

To help you better understand the concept of fault codes, here are a few examples along with their solutions offered by the Jaltest Paccar MX13 scanner.      

• Paccar P3841 Fault Code: It indicates problems with the powertrain that must be fixed quickly before the catalytic converter fails and the truck moves into downtime.
• Paccar Fault Code P1495/P1496: This fault code means that the engine protection has been enabled causing the EGR to be disabled and the system to go into preventative safety measures. Fix this issue within 10 hours to prevent it from going into EGR derate.
• Paccar MX13 Fault Code P1515: This fault code is seen on the Jaltest Paccar MX13 diagnostic software when the PCM detects that the commanded throttle blade position and the actual throttle position are not within a calibrated range of each other.

If this occurs for less than 1 second, the code sets, and the traction control module is turned off. The warning light in the PCM will not turn off until three driving cycles have been completed as that signals that this fault code has been cleared.

Our Jaltest Paccar diagnostic software assists you to both foresee and be forewarned of major impending faults as well as helping you to go by symptoms of fault codes and have them resolved before a minor issue becomes a major problem.

Let us look at both the scenarios independently.

The Paccar engine diagnostic tool has a diagnostic menu that offers two possibilities. One is full system scans and the other is scanning by symptoms.

In the first case, you can periodically carry out scans of all the systems to check for any minor problem and have it rectified before it becomes a full-blown issue. Typically, fault codes detected here are temporary and go away within a few driving cycles without the need for any major overhaul. A full system scan will check central computers, chassis trouble, electronic modules, climate HVAC, lighting, instrument clusters, and more.

If you use the Paccar engine diagnostic software to carry out preventive maintenance through full system scans, you can be sure that your fleet will not face any major downtime.

The other case is scanning by symptoms that is whenever a fault code is generated in the ECU. You have to connect the Jaltest Paccar engine diagnostic tool to the onboard computer and get a rundown of the fault, its interpretation, and the actions to be taken to clear it.

Once you have logged in with the Jaltest Paccar diagnostic software, you can select parameters from the drop-down menu to carry out a variety of functions. These include changing metrics for fuel consumption, power take-off control, activating and deactivating conditions of the brake pedal, engine speed control, and many others.

What helps is the detailed live technical and maintenance data that you get in real-time along with detailed wiring diagrams that help to pinpoint the location of the fault in the system or components. Taking resolving action therefore becomes very simplified.     

Paccar MX13 Diagnostic Software and Forced Regens

While the Paccar MX13 scan tool can perform simple functions like warning about loose wires, it can also carry out very complex functions such as forced regens. Since forced regens are exclusive to diesel engines, this aspect will now be taken up in detail.

Force regens is necessary only on diesel engines regardless of the make or model of the engines. In diesel engines, soot forms on the diesel particulate filter. Typically, passive regens are enough to clear this soot. However, in severe cases, this is not possible and forced regens have to be applied to prevent the engine from seizing up and putting the truck into limp mode. When a fault code related to this fault shows up, immediate action must be taken to clear it.

Soot buildup takes place generally on short-haul trucks that do not run for long stretches at a time. When this fault code pops up on the Jaltest Paccar MX scanner, you will be guided on how to bring the engine back to peak operating mode. The level of Forced regens resolutions ranges from High to Very High on our software depending on the severity of the soot accumulation.

Clearing soot requires the engine to be run continuously for around 40 minutes at a rev that will be decided by our Jaltest Paccar diagnostic software. The increase in the temperature of the exhaust gasses burns away the soot accumulation in the forced regens action.
