Key Features
- Correct Spring Tension and Bite Angle — Manufactured to the exact hardness and coil geometry required to maintain consistent clamp load on DCA-series generator fasteners, preventing loosening under vibration.
- Genuine OEM Component — A true Multiquip OEM part, meaning it carries the same material specification and dimensional profile as what shipped from the factory — no guesswork on sizing or thread compatibility.
- Direct Replacement Hardware — Drops straight into the existing fastener position on covered DCA-series models; no rework or adapter hardware needed to complete the installation.
- Broad DCA-Series Coverage — Confirmed fitment across DCA70SSIU, DCA150SSJU, DCA150SSJU2, DCA56SPX, DCA45SSIU2-GEER, DCA70SSIU50HZ, DCA70SSIU60HZ, and DCA70USI ultra-silent generator models.
- Vibration Resistance — Lock washers in generator applications bear continuous engine and alternator vibration loads; using the specified part maintains fastener integrity and prevents hardware migration over time.
A lock washer is a hardened fastener component placed beneath a nut or bolt head to resist loosening caused by vibration, torque fluctuation, and thermal cycling. In diesel generator sets like the DCA-series, where engine vibration is constant during operation, lock washers play a critical role in keeping assemblies securely fastened across the service life of the machine. When a lock washer is worn, deformed, or missing, fasteners can gradually back out, leading to loose panels, misaligned components, or more serious mechanical failures that require extensive repairs.
