Key Features
- Genuine OEM Material Grade — Manufactured to the same material and dimensional specification as the original, so it seats and locks exactly as intended in the axle assembly.
- Direct Drop-In Replacement — Matches the original pin diameter and length, installing through the existing clevis or castle nut bore without rework or modification.
- Verified Fitment for MT-L II Axles — Confirmed compatibility with MT-L II axle assemblies, cross-referenced to Wacker Neuson part 1000288639.
- Retains Critical Fasteners Securely — Prevents axle pins, bolts, and retaining hardware from backing out during operation, maintaining the structural integrity of the axle connection.
- Safety-Critical Retention Component — A missing or failed cotter pin can allow fasteners to loosen or disengage under load, making timely replacement essential for safe operation.
A cotter pin is a small but essential locking fastener used to secure axle pins, castle nuts, and clevis connections against rotation or withdrawal. Once inserted through a drilled hole and bent open, it physically prevents the mating fastener from backing out under vibration or load. When a cotter pin is bent, corroded, or missing, the fastener it retains can work loose during operation, leading to play in the axle assembly and potential loss of mechanical connection — making it a routine but important inspection and replacement item during servicing.
