Multiquip 8201611004 Coupling Disk

The Multiquip 8201611004 Coupling Disk is a genuine OEM component designed for the DCA300SS, DCA400SS, and MQP240 series ultra-silent diesel generators. Sourced directly from Multiquip, this coupling disk meets the exact material and dimensional specifications of the original part installed at the factory. It is confirmed to fit a wide range of DCA-series models including DCA300SSC, DCA300SSCU, DCA300SSK, DCA400SSI, DCA400SSK, DCA400SSV, DCA400SPK, and MQP240, among others. When you order 8201611004 from DHS Equipment, you receive an authentic Multiquip replacement backed by OEM quality assurance.

Key Features

• Genuine OEM Material Integrity — Manufactured to the same torsional flex and durometer specifications as the original, ensuring the disk absorbs drivetrain shock without cracking or deforming prematurely.
• Drop-In Fitment — Matches the original bolt pattern and hub profile of DCA300SS and DCA400SS series generator sets, allowing direct installation without machining or modification.
• Broad DCA-Series Compatibility — Fits DCA300SSC, DCA300SSCU, DCA300SSK, DCA400SSI, DCA400SSK, DCA400SSV, DCA400SPK, MQP240, and multiple Tier 4 variants including DCA300SSJU4F and DCA400SSI4F series.
• Smooth Power Transmission — A correctly functioning coupling disk isolates engine vibration from the alternator, protecting the generator end bearings and maintaining stable power output under load.
• Protects High-Value Drivetrain Components — A worn or cracked disk transfers shock loads directly to the alternator coupling flange, risking costly damage to the generator end — replacing it at first sign of wear prevents escalating repair costs.

The coupling disk is a flexible drive element positioned between the engine flywheel and the generator alternator. Its primary role is to transmit rotational power from the engine to the alternator while absorbing torsional shock and vibration, which prevents those forces from damaging the alternator bearings and coupling flanges. When a coupling disk deteriorates — through cracking, chunking, or compression set — it can cause erratic power output, abnormal drivetrain noise, and accelerated wear on surrounding components, making timely replacement critical to keeping a generator set running at full rated output.
