3P0165 Pulley-Fan Drive — Cat 120G 12G

This pulley is a critical component of the engine's cooling system, driving the fan to ensure optimal radiator airflow and engine temperature regulation. Manufactured to meet stringent material and dimensional standards, it provides a durable and reliable alternative to a worn pulley that may exhibit visible cracks or bearing play. Operators may notice increased engine operating temperatures or unusual noises from the front of the engine when this component begins to fail.

Failure Symptoms

A failing fan drive pulley may first manifest as a high-pitched squealing noise from the engine compartment, especially under load. If left unaddressed, the pulley can seize or wobble, leading to a loss of fan speed and reduced engine cooling efficiency. This can result in the engine overheating, potentially causing significant internal damage.

Installation Tip

Ensure the mounting surface on the engine crankshaft is clean and free of debris before installation. Avoid overtightening the pulley bolts, as this can strip the threads or damage the pulley.

Service Note

Inspect the fan, fan shroud, and fan belt for wear or damage when replacing the fan drive pulley.
