The Multiquip 1686116023 is a genuine OEM Camshaft Assembly Fuel Tlg-12Spx3 D902-E2B designed for DLW300ES series diesel light welder units. Sourced directly from Multiquip, this assembly meets the exact specifications required for the D902-E2B engine used in these machines, ensuring the fuel system and valve timing operate exactly as the manufacturer intended. This part is confirmed for DLW300ES, DLW300ESA, and DLW300ESA1 models, making it a direct, confidence-inspiring replacement when the original component has worn or failed.
Key Features
- Genuine OEM Valve Timing Accuracy — Manufactured to the precise lobe profile and journal tolerances of the original D902-E2B engine specification, maintaining correct fuel delivery timing throughout the power stroke.
- Drop-In Engine Compatibility — Engineered as a direct replacement for the D902-E2B engine assembly; aligns with existing bearing journals and gear interfaces without reworking the engine block.
- Confirmed Fitment for DLW300ES Series — Verified for DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welders, so you can order with confidence knowing this is the correct assembly for your machine.
- Restored Engine Output and Fuel Efficiency — A worn or damaged camshaft causes erratic fuel delivery, rough running, and reduced power output; replacing it with 1686116023 restores smooth, consistent engine performance.
- Fuel System Integrity — Correct camshaft timing is critical to preventing over-fueling or fuel starvation conditions that can damage downstream engine components and affect weld quality on the job.
The camshaft assembly controls the precise timing of the engine's intake and exhaust valves in coordination with the fuel injection cycle. In a diesel engine like the D902-E2B, the camshaft's lobe profile directly governs how and when fuel enters the combustion chamber — any wear to the lobes or journals disrupts this timing, leading to hard starting, loss of power, excessive smoke, or uneven engine operation. Replacing a worn camshaft assembly restores the engine's ability to run cleanly and deliver consistent output, which is especially important in a diesel light welder where stable engine speed directly affects weld arc quality.
