Wacker Neuson 5000012257 Retaining Ring 13mm 73123 Form A

The Wacker Neuson Retaining Ring 13mm 73123 Form A is a genuine OEM component designed for the BS-series vibratory rammer lineup, including the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, and BS70-2i families. As a direct-source OEM part, is manufactured to the exact material grade and dimensional specification called out in the original Wacker Neuson parts schema. This retaining ring fits an exceptionally wide range of BS-series rammer configurations — standard, oil-injected, variable-speed, EU, and high-altitude variants — making it a reliable single-part-number solution across your fleet. Confirm your model number against the fitment list before ordering to ensure a correct match.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to the exact 13mm Form A profile specified by Wacker Neuson, ensuring the ring seats and retains with the correct snap force for this application.
• Drop-In Installation — Replaces the original retaining ring without reworking the groove or mating bore; the Form A geometry matches the machined groove dimensions used across the BS rammer family.
• Broad BS-Series Coverage — Fits BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS500, BS600, BS700, BS65-V, and related model variants, including standard, oil-injected, EU, and high-altitude configurations.
• Maintains Internal Component Retention — A correctly installed retaining ring prevents axial movement of internal shafts and assemblies; a worn, deformed, or missing ring can allow components to shift under impact loads, leading to accelerated wear or internal damage.
• OEM Part Number Traceability — Sourced directly through the Wacker Neuson parts network under part number 5000012257, so the specification reference 73123 Form A is fully documented for service records and warranty purposes.

A retaining ring — also called a snap ring or circlip — is a small but load-bearing fastener used to lock rotating or sliding components in position along a shaft or within a bore. In a vibratory rammer, these rings hold internal drivetrain and guide components in precise axial alignment, allowing the machine to deliver consistent impact force stroke after stroke. When a retaining ring deforms, loses its spring tension, or is missing entirely, the retained component can migrate under the machine's repetitive impact loads, causing uneven wear, noise, and potential failure of the surrounding assembly.
