Atlas Copco Smartroc T40 Troubleshooting and Complete Solution

The Atlas Copco Smartroc T40, powered by a Caterpillar C7.1 engine, is state-of-the-art equipment designed for the most demanding jobs. However, it is not immune to malfunctions, particularly in connection with the Adblue system and anti-pollution devices such as SCR (selective catalytic reduction) or DPF (particulate filter). These problems can cause costly downtime and reduce productivity.

In this article, we explain how to identify and solve an Adblue problem on the Smartroc T40, using a precise and effective methodology. We also discuss the benefits of removing the anti-pollution devices, to restore your machine's reliability and performance.

Why does an Adblue problem affect the Smartroc T40?

Anti-pollution systems, while essential for reducing emissions, pose technical challenges. They depend on regeneration cycles that don't always work properly. On the Smartroc T40, an Adblue problem often manifests itself as saturation of the particulate filter (DPF). This leads to fault codes that signal a malfunction.

Frequently detected faults include :

• SPN 3719 FMI 16: Moderate soot overload in the DPF, affecting regeneration.
• SPN 3719 FMI 0: A critical saturation that completely blocks system operation.

These faults can reduce Caterpillar C7.1 engine power, increase fuel consumption and bring the machine to a standstill. Ignoring these faults often worsens the situation, making prompt intervention essential.

Steps to solve an Adblue problem on the Smartroc T40

1. Diagnose fault codes

To begin with, we use a diagnostic tool to analyze active fault codes. This step precisely identifies anomalies, such as DPF regeneration problems or SCR faults.

2. Analyze ECU data

Next, we extract the data stored in the ECU's memory and analyze the Caterpillar C7.1 engine parameters. This allows us to understand the exact causes of the Adblue problem.

3. Create a customized program

To resolve faults once and for all, we create a customized program. This deactivates emission control devices, including SCR and DPF, while optimizing engine performance.

4. Install the program in the calculator

Once the program has been finalized, we flash it into the machine's ECU. This operation eliminates the limitations caused by the Adblue system and restores optimum engine performance.

5. Check fault clearance

After modification, we check that all active fault codes have been deactivated or deleted. This step ensures that the machine no longer reports emission-related faults.

6. Carry out practical tests

Finally, we carry out field tests with the customer. These tests ensure that the machine works perfectly and that power is restored.

What are the advantages of removing the Adblue system from the Smartroc T40?

Eliminating the Adblue system, as well as emission control devices such as SCR and DPF, offers a number of significant benefits. Although these systems are designed to comply with environmental standards, their complexity can lead to costly and unnecessary breakdowns.

Key benefits :

• Reduced costs: You eliminate maintenance costs and Adblue purchases.
• Improved reliability: The machine no longer suffers from breakdowns due to DPF regeneration.
• Optimized performance: the Caterpillar C7.1 engine regains its full power without restrictions.
• Greater simplicity: A machine without SCR or DPF is easier to operate and maintain.

Thanks to these advantages, your Smartroc T40 can operate reliably, even in the most demanding environments.
