Multiquip 1497174280 Pulley Fan Drive Kubota - OEM Replacement Part

The Pulley Fan Drive is a critical component in the Kubota EA330-E3-NB3-HGMS-1 diesel engine's cooling system, transferring rotational power from the engine crankshaft to drive the cooling fan. This pulley works in conjunction with the fan belt and tension pulley to maintain proper engine operating temperatures during compaction operations.

During routine maintenance, inspect this pulley for wear, cracks, or surface damage when performing fan belt adjustments. According to Multiquip maintenance procedures, the fan belt deflection should be checked by applying 98N (approximately 10 kgf) of force at the midpoint between the fan drive pulley and tension pulley. Replace the pulley if the belt shows signs of excessive wear or if it contacts the bottom of the pulley groove, as this indicates pulley wear that can lead to belt slippage and inadequate cooling.

Compatible with Multiquip vibratory roller models:

• MRH601DS

This pulley is essential for preventing engine overheating during extended operation, particularly when working on graded surfaces up to 35% (20°). Failed or worn pulleys can cause belt damage, reduced cooling efficiency, and potential engine damage.
