CAT 972K loader with C9.3 ACERT engine

The Caterpillar 972K wheel loader is designed to improve operator comfort, efficiency and productivity. It owes its popularity to a huge bucket that allows for quick transport of material or excavated material to the place of storage. A wide range of other work tools and bucket types are also available, so you can tailor the machine to your specific application.

The model is equipped with a six-cylinder turbocharged 568 in³ (9.3 liter) Cat C9.3 ACERT engine with a power of 288 HP (215 kW). The engine meets Tier 4 Interim / Stage IIIB emission standards and is equipped with a diesel particulate filter (DPF). When creating it, the designers took into account the optimization of power density, its reliability, service life and fuel economy.

Repair of the Caterpillar 972K loader

We started the repair by checking the errors reported by the charger’s computer. After verifying them, we started repairing the CAT 972K loader’s DPF filter. The first step was to disconnect the particulate filter sensors and connect the Caterpillar DPF Delete Kit in their place.

The next step was to remove the clogged particulate filter from the machine. The insert that no longer fulfilled its role was removed from the dismantled filter, and then the filter was reinstalled in the machine’s engine. The last stage of the repair consisted of testing the engine with an emulator connected and the DPF removed. It was successful and loader was able to work again.
