The Wacker Neuson Cotter Pin is a genuine OEM component designed for the BS60, BS70, BS72, and DS70Y series gasoline and diesel rammers. As a direct OEM replacement, this cotter pin is manufactured to the same specifications as the original part installed at the factory, ensuring it integrates correctly within the rammer's mechanical assembly. Fitment covers a broad range of configurations across the BS60-2, BS60-4As, BS70-2, BS70-2plus, BS70-4As, BS72-4As, and DS70Y series.
Key Features
- Genuine OEM Material Integrity — Manufactured to original specification with the correct pin diameter and material grade to hold securely under the repetitive impact loads generated by a rammer.
- Drop-In Installation — Matches the exact dimensions of the OEM cotter pin, fitting directly into the clevis or shaft bore without modification to surrounding hardware.
- Wide Rammer Family Coverage — Confirmed fitment across BS60-2, BS60-4As, BS70-2, BS70-2plus, BS70-4As, BS72-4As, and DS70Y series rammers in standard, US, HA, CN, and LRC configurations.
- Mechanical Retention You Can Count On — A correctly installed cotter pin prevents critical fasteners from backing out during operation; a missing or failed pin can allow shaft or linkage components to disengage mid-use.
- Operational Safety Relevance — Cotter pins are a positive-locking safety feature in rammer drivetrains; using the correct OEM-spec pin ensures the locking tines deform and seat as designed, preventing unintended release.
A cotter pin is a small split-pin fastener inserted through a drilled hole in a shaft or bolt to lock a nut, clevis pin, or similar component in place. In a vibratory rammer, where the drivetrain is subjected to continuous high-frequency impact forces, cotter pins provide a critical mechanical lock that prevents nuts and linkage pins from vibrating loose. When a cotter pin shears, deforms beyond use, or is missing entirely, the fastener it secures can back out and allow connected components to shift or disengage, leading to mechanical damage or loss of machine control.
