What is the fan belt model number for Komatsu 270-7?
2 Answers
The fan belt model number for Komatsu 270-7 is 8PK1520. Function of automotive fan: The automotive fan blows towards the radiator to cool it down and dissipate heat from the engine. When the fan rotates, it creates suction force on the air, accelerating axial airflow, which enhances the cooling of coolant passing through the radiator core while simultaneously cooling the engine block housing and surrounding components. Engine cooling system: Automotive engines operating under high-temperature conditions require proper cooling to maintain optimal working temperature, ensuring good engine performance, durability, and meeting exhaust emission requirements.
I've dealt with this type of issue quite often. The fan belt model for the Komatsu 270-7 is typically 5PK1560, which is based on standard specifications and suitable for most excavator engine cooling systems of similar types. The belt dimensions are 5 grooves and approximately 1560 mm in length, matching Komatsu's design. When replacing it, don't be careless—first check the old belt for any labels to confirm the model number. Don't just guess; if the size is wrong and installed improperly, it can lead to incorrect tensioning, causing unstable fan operation, engine overheating, or premature belt failure. It's recommended to use a tension gauge to ensure the tightness stays within a displacement range of 10-12 mm. During routine maintenance, inspect the belt surface every few months for cracks or signs of aging. If any issues are detected early, replace the belt promptly to avoid work delays or higher repair costs. Always remember to turn off the engine before performing any operations—safety comes first.
