The Multiquip EM745 Cotter Pin is a genuine OEM fastening component designed for AR13HA/HAR, AR13D, AR13HC, and AR13H asphalt ride-on rollers, as well as MQ600TD80-TLRP and MQ600TD80-TLRB trash pumps. As a direct OEM replacement, the EM745 matches the original specification exactly, ensuring correct installation without modification. Sourced directly through authorized Multiquip supply channels, this cotter pin delivers the same fitment and material grade as the part that left the factory. Confirm your model code against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Material Grade — Manufactured to the same shear-resistant metal specification as the original, ensuring the pin holds under the dynamic loads present in roller and pump assemblies.
- Drop-In Installation — Matches the original pin diameter and leg length for direct insertion into existing clevis, axle, or linkage bores with no rework required.
- Broad Fitment Across Two Equipment Families — Confirmed fitment for AR13HA/HAR, AR13D, AR13HC, and AR13H ride-on rollers, plus MQ600TD80-TLRP and MQ600TD80-TLRB trash pumps.
- Secures Critical Moving Assemblies — Locks pins, shafts, and linkage connections in place, preventing unintended axial movement during operation on compaction and pumping equipment.
- Safety-Relevant Fastener — A missing or failed cotter pin can allow connected components to disengage during operation; replacing with the correct OEM part maintains the mechanical integrity of pinned joints.
A cotter pin is a small split fastener inserted through a drilled hole in a bolt, shaft, or clevis pin and then bent open on the other side to lock the assembly in place. Its job is to prevent unintended movement or separation of the connected components during machine operation. On ride-on rollers and trash pumps, cotter pins are used to secure linkages, axles, and control connections — when a pin shears, corrodes, or goes missing, the joint it was holding can shift or come apart entirely, leading to loss of control or mechanical damage that stops the machine.
