Key Features

• Genuine OEM Gear Integrity — Sourced directly from Multiquip, this gear ring meets the exact tooth profile and material spec of the original D902-E2B engine fitment, ensuring proper mesh and load transfer.
• Direct Engine Replacement — Engineered to drop into the D902-E2B engine position with correct bore and ring dimensions, matching the original mounting configuration.
• DLW Series Compatibility — Confirmed fitment for DLW300ES and DLW400ES series diesel light welders, covering the full ES, ESA, and ESA1 variants.
• Sustained Power Transmission — A properly seated gear ring maintains consistent rotational drive through the engine, supporting stable output for welding and generation operations. A worn or damaged ring introduces slippage, noise, and power loss.
• Verified OEM Part Number — Part number 1681363820 is the authoritative Multiquip reference for this component, eliminating fitment uncertainty when reordering.

The gear ring serves as a critical drivetrain component within the engine assembly, transmitting rotational force between the engine's internal rotating parts. It must maintain precise tooth engagement to deliver smooth, uninterrupted mechanical drive — any wear, cracking, or tooth damage disrupts this transfer and can lead to rough running, excessive vibration, or outright engine failure. Replacing a worn gear ring with the correct OEM part restores the mechanical integrity the engine depends on for consistent performance.
