Air Inlet and Exhaust System 64 UENR0623-02 Air Inlet and Exhaust System i04170052 Air Inlet and Exhaust System - Inspect A general visual inspection should be made to the air inlet and exhaust system. Make sure that there are no signs of leaks in the system. There will be a reduction in the performance of the engine if there is a restriction in the air inlet system or the exhaust system. Illustration 55 g02857416 Typical example Hot engine components can cause injury from burns. Before performing maintenance on the en- gine, allow the engine and the components to cool. 4. Inspect the orifice in the boost pressure chamber (1) for blockages. If necessary, remove any blockages. Note:
The boost pressure chamber is located on the side of the engine oil cooler. Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts. i05239437 Turbocharger - Inspect When working on an engine that is running, avoid contact with hot parts and rotating parts. 1. Inspect the engine air cleaner inlet and ducting in order to ensure that the passageway is not blocked or collapsed. Hot engine components can cause injury from burns. Before performing maintenance on the en- gine, allow the engine and the components to cool. 2. Inspect the engine air cleaner element. Replace a dirty engine air cleaner element with a clean engine air cleaner element.
Refer to Operation and Maintenance Manual, “Engine Air Cleaner Element (Dual Element) - Clean/Replace” or Operation and Maintenance Manual, “Engine Air Cleaner Element (Single Element) - Replace” for the correct procedure. NOTICE Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. 3. Check for dirt tracks on the clean side of the engine air cleaner element. If dirt tracks are observed, contaminants are flowing past the engine air cleaner element and/or the seal for the engine air cleaner element.
