The Multiquip 1687574280 Fan Drive Pulley Tlg-12Spx3 D902-E2B is a genuine OEM component designed for DLW300ES series diesel light welder/generator units. As a factory-sourced part, it matches the original specification for profile, bore, and belt groove geometry — ensuring correct belt engagement without adjustment or shimming. This pulley is compatible with DLW300ES, DLW300ESA, and DLW300ESA1 models, making it a straightforward like-for-like replacement when servicing the cooling fan drive system.
Key Features
- OEM Belt Groove Accuracy — Manufactured to the exact Tlg-12Spx3 groove profile, ensuring proper belt seating and eliminating belt slip or accelerated wear under load.
- Direct-Fit D902-E2B Engine Compatibility — Engineered specifically for the Kubota D902-E2B engine configuration used in DLW300ES series machines, installing directly onto the existing drive shaft without modification.
- DLW300ES Series Fitment — Confirmed fit for DLW300ES, DLW300ESA, and DLW300ESA1 Multiquip diesel light welder/generators.
- Cooling System Integrity — A correctly sized and balanced fan drive pulley maintains proper fan speed across the engine RPM range, supporting consistent coolant and air temperature management during extended generator operation.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying full OEM traceability and manufactured to the same standards as the original production component.
The fan drive pulley transfers rotational power from the engine crankshaft to the cooling fan via a drive belt, controlling the fan speed that moves air across the radiator and engine cooling surfaces. If the pulley is worn, cracked, or incorrectly sized, the belt can slip or jump, reducing fan output and causing the engine to run hot — particularly under the sustained load conditions typical of a welder/generator in field use. Replacing a damaged or worn pulley with the correct OEM part restores the proper drive ratio and protects the engine from heat-related stress.
