The Multiquip 516775 is a genuine OEM Motor Shaft Coupler designed for the LS-series hydraulic-driven concrete pumps, including the LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD. As a direct OEM replacement sourced through Multiquip's authorized parts network, the 516775 meets the original engineering tolerances required for proper power transmission in these concrete pump models. Whether you are servicing a single unit or maintaining a fleet, specifying the correct Motor Shaft Coupler by part number 516775 ensures the drivetrain interface is restored to its original operating condition. DHS Equipment stocks this part to keep your LS-series machines back on the job with minimal wait.
Key Features
- Genuine OEM Torque Integrity — Manufactured to the exact torsional and dimensional spec of the original coupler, ensuring full power transfer between the motor and pump without slippage or flex loss.
- Direct Drivetrain Interface — Engineered to align precisely with the motor and pump shafts on LS-series units, dropping into the existing mounting configuration without adaptation.
- Broad LS-Series Compatibility — Confirmed fitment across the LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD hydraulic concrete pumps.
- Sustained Pumping Performance — A properly functioning shaft coupler keeps the hydraulic pump drive smooth and consistent; a worn or failed coupler leads to vibration, power loss, and unplanned stoppages during concrete placement.
- Verified Part Number — Order with confidence using Multiquip part number 516775 — the same number referenced in OEM service documentation for these pump models.
The motor shaft coupler connects the drive motor to the hydraulic pump assembly, transmitting rotational force from one component to the other while accommodating minor shaft misalignment during operation. In a concrete pump application, this coupling is under continuous load and must maintain a secure, vibration-resistant connection to deliver consistent hydraulic pressure to the pumping circuit. When the coupler wears, cracks, or fails, the motor and pump become effectively disconnected, causing a complete loss of pumping output and potential secondary damage to adjacent drivetrain components.
