The Wacker Neuson Cotter Pin is a genuine OEM cotter pin designed for the BPS1550B, BPS2050B, and A5000/160B series machines. Sourced directly from Wacker Neuson, this part is manufactured to the exact specifications of the original component, ensuring a drop-in replacement with no guesswork. Cross-reference part number against your machine's parts diagram before ordering to confirm fitment with your specific model.
Key Features
- Genuine OEM Material Integrity — Manufactured to the precise hardness and dimensional tolerances required for a cotter pin application, so the pin shears or retains exactly as the original design intends.
- Direct Drop-In Installation — Matches the original hole diameter and pin length, so it seats and spreads without modification to the surrounding hardware.
- Broad Model Coverage — Compatible with BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series equipment, covering a wide range of Wacker Neuson submersible pump models.
- Secure Retention Under Load — A correctly fitted cotter pin locks connected components firmly in place, preventing unintended movement or disassembly during operation. A missing or worn pin can allow shafts, bolts, or clevis pins to walk free under vibration.
- Safety-Critical Fastener — Cotter pins are often the last line of retention on linkages and fasteners; using an OEM-spec replacement ensures the locking function is not compromised by undersized or incorrect-grade substitutes.
A cotter pin is a simple split or solid pin inserted through a drilled hole in a bolt, shaft, or clevis to prevent the fastener from backing out or separating under vibration and load. Once installed and bent open, it mechanically locks the assembly together, acting as a fail-safe retention device. When a cotter pin is worn, deformed, or missing entirely, the fasteners it secures can loosen and migrate, which can lead to component separation and potential damage to surrounding parts.
