The Multiquip 0641400430 Split Pin is a genuine OEM fastening component designed for Multiquip trash pump models including MQ62TDD, QP4TK, QP4TB, QP4TKT, QP4TZ, and QP4TH. Sourced directly through Multiquip's authorized parts network, this split pin meets the original equipment specification for correct fit and function. Sold by DHS Equipment, it is the exact part your pump was built with — no guesswork on compatibility.
Key Features
- Genuine OEM Construction: — Manufactured to the original pin diameter and material grade, ensuring the correct shear resistance and retention force for trash pump applications.
- Drop-In Installation: — Sized to the original bore and clevis geometry, so it installs exactly as the factory part did — no filing, bending, or modification needed.
- Broad Trash Pump Fitment: — Confirmed for MQ62TDD, QP4TK, QP4TB, QP4TKT, QP4TZ, and QP4TH models, covering a wide range of Multiquip quick-prime and standard trash pump configurations.
- Secure Retention Under Load: — A properly seated split pin locks moving components in position, preventing shaft, clevis, or linkage separation during high-vibration pump operation.
- Safety-Critical Fastener: — Split pins serve as a primary anti-loosening device on rotating and pivoting assemblies; using the correct OEM-spec pin is essential to safe pump operation and preventing component loss in the field.
A split pin — also known as a cotter pin — is a small but essential fastener used to lock bolts, clevis pins, and shafts in place on mechanical assemblies. It passes through a hole in the fastener or shaft and its legs are bent outward to prevent the fastener from backing out under vibration or load. On trash pumps like the QP4TH and MQ62TDD, these pins secure critical linkage and drive components that are subject to continuous vibration during operation. A missing or worn split pin can allow fasteners to loosen and components to shift or detach, leading to mechanical failure or unsafe conditions.
