The Multiquip 8351611004 Coupling Disk is a genuine OEM component designed for the DLW500ESA4 diesel light welder. Sourced directly from Multiquip, this part meets the original design and material specifications for the DCA-25SSI(II) application. If you are servicing or rebuilding a DLW500ESA4 unit, verifying part number 8351611004 against your machine's parts manual will confirm correct fitment before installation.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original coupling disk, ensuring consistent torque transfer and engagement characteristics.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the DCA-25SSI(II) coupling position on DLW500ESA4 welders, aligning with the original mounting interface.
- Confirmed Fitment — Verified for use with the Multiquip DLW500ESA4 diesel light welder series.
- Maintains Drive Integrity — A functioning coupling disk transmits power smoothly between the engine and generator end; a worn or cracked disk leads to vibration, slippage, and uneven electrical output.
- Electrical System Compliance — Correct coupling engagement is critical to maintaining stable generator output frequency and voltage — using the proper OEM disk helps protect connected equipment and operator safety.
A coupling disk serves as the flexible link between the drive engine and the alternator or generator end of a welder-generator unit. It absorbs torsional shock and minor misalignment during startup and operation, protecting both the engine crankshaft and the generator rotor from stress. When a coupling disk deteriorates — through cracking, hardening, or physical damage — the result is increased vibration, rough engagement, and ultimately a loss of stable power output that can affect welding arc quality and connected tool performance.
