The Wacker Neuson is a genuine OEM Cotter Pin 1.6 x 16 designed for a wide range of Wacker Neuson walk-behind concrete trowels, tandem rollers, and remote-controlled trench rollers. As a direct OEM replacement, this cotter pin is manufactured to the exact material and dimensional specifications required by the machines it serves, ensuring a secure, play-free installation every time. Fitment spans the CT36 and CT48 walk-behind trowel series, the RD7 tandem roller family, and the RTKx-SC3 trench roller. Confirming part number against your machine's parts diagram before ordering is always recommended to ensure correct application.
Key Features
- Exact OEM Dimensional Specification — Manufactured at the precise 1.6 x 16 mm sizing required for correct pin retention; undersized or oversized cotter pins can back out or fail to seat properly in the clevis or shaft bore.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this cotter pin meets the same material grade and corrosion-resistance standard as the original hardware installed at the factory.
- Drop-In Installation — Installs directly into the existing hole or clevis bore with no drilling, reaming, or hardware modification; the 1.6 mm wire diameter is matched to the receiving hole on your machine's linkage or shaft.
- Broad Fitment Across Multiple Machine Families — Compatible with CT36 and CT48 walk-behind trowels, RD7 series tandem rollers (including RD7H, RD7He, RD7Ye, and RD7A variants), and RTKx-SC3 and RTK82-SC3 remote-controlled trench rollers.
- Retention-Critical Hardware — Cotter pins are a safety-relevant fastener; a missing or failed cotter pin can allow clevis pins, axle pins, or control linkage pins to walk out during operation, leading to loss of mechanical control or component separation.
A cotter pin is a split fastener inserted through a drilled hole in a clevis pin, shaft, or bolt to lock it in place and prevent it from backing out under vibration or load. On compact construction and concrete finishing equipment, cotter pins secure linkage joints, handle assemblies, and other mechanical connections that are subject to constant vibration during operation. When a cotter pin shears, corrodes through, or goes missing, the pin it retains can migrate out of its bore, causing slack in the linkage, unexpected disconnection of a mechanical assembly, or accelerated wear on surrounding components. Replacing a worn or missing cotter pin promptly with the correct OEM specification part restores the mechanical integrity of the joint and keeps the assembly functioning as designed.
