5w-3403-5w-3402 Air Filter 5W 3403 — Cat Engine 3116 Excavator 214B

This is a high-efficiency air filter assembly, designed to capture airborne contaminants before they enter the engine's combustion chambers, protecting vital internal components. Manufactured to meet stringent OEM quality and filtration standards, it provides superior protection against wear-causing dust and debris compared to a clogged or damaged filter. Operators may notice a reduction in engine power, increased fuel consumption, or black smoke from the exhaust if this air filter becomes excessively dirty or fails to seal properly.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A clogged air filter typically first manifests as a gradual decrease in engine power and a slight increase in fuel consumption. If left unaddressed, the engine may start to run rough, produce black exhaust smoke, and experience difficulty accelerating. In severe cases, restricted airflow can lead to engine overheating and potential internal damage due to inadequate air for combustion.

Installation Tip

Ensure the air filter housing is completely clean and free of debris before installing the new filter. Check that the filter is seated correctly and the housing seals are intact to prevent unfiltered air from entering the engine.

Service Note

Inspect the intake manifold and turbocharger (if equipped) for oil or soot buildup when replacing the air filter.
