The Wacker Neuson Cotter Pin 1-3/16 Long.073 Dia is a genuine OEM fastener designed for the RD12, RD7, CRT36, and CRT48 series machines. As a direct factory replacement, part is manufactured to the same specifications as the original, ensuring correct installation and a secure hold in the intended application. This pin fits an extensive range of tandem rollers and ride-on concrete trowels across multiple model generations, making it a versatile stocking item for fleets running mixed Wacker Neuson equipment.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original material and dimensional specification for this cotter pin diameter and length, ensuring the correct retention force in the fastened assembly.
- Direct Drop-In Installation — At 1-3/16 inches long and .073 inches in diameter, this pin installs into the original bore without any modification to the surrounding hardware.
- Broad Cross-Series Fitment — Confirmed fit across RD12, RD7, CRT36, and CRT48 model families, covering both tandem roller and ride-on trowel applications in a single part number.
- Retention Integrity — A correctly installed cotter pin locks clevis pins, bolts, or shaft hardware in position; a missing or failed pin allows connected components to back out or shift under vibration and load.
- Safety-Critical Fastener — Cotter pins are used in steering, linkage, and control assemblies where loss of retention can affect machine handling; always replace with the correct OEM-spec pin rather than a non-dimensioned substitute.
A cotter pin is a split fastener inserted through a drilled hole in a pin or bolt to prevent it from backing out under vibration, load cycles, or repeated movement. Once installed and bent open, it mechanically locks the retained component in place, preventing accidental disassembly during operation. When a cotter pin shears, corrodes through, or is simply missing, the hardware it secures can work loose, leading to play in linkages, loss of adjustment, or component separation — all conditions that must be corrected before the machine is returned to service.
