The Multiquip 516787 is a genuine OEM Remix Shaft Coupler designed for the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic-driven concrete pumps. As a direct OEM replacement, this coupler is manufactured to the same standards as the original component, ensuring a proper mechanical connection between the remix shaft drive and the hopper agitator system. Confirm your model code against the verified fitment list before ordering — this part covers a wide range of Multiquip LS-series concrete pump models.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material specifications as the original, ensuring the remix shaft transmits torque without slippage or premature wear.
- Direct Drop-In Replacement — Engineered to connect directly to the existing remix shaft and drive interface on LS-series pumps, maintaining the correct shaft alignment and coupling engagement.
- Broad LS-Series Fitment — Verified compatible with LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic concrete pump models.
- Sustained Agitator Performance — A properly functioning remix shaft coupler keeps concrete moving in the hopper, preventing material segregation and blockages during continuous pumping operations.
- Operational Safety Relevance — A failed or cracked coupler can cause sudden loss of hopper agitation, leading to pump blockages and uncontrolled pressure buildup in the line — replacing it promptly maintains safe, predictable pump operation.
The remix shaft coupler connects the drive source to the agitator shaft inside the concrete pump hopper. Its job is to transfer rotational force from the hydraulic drive motor to the remix shaft, which continuously stirs the concrete in the hopper to keep it workable and prevent it from setting or separating before it enters the pump cylinders. When this coupler wears, cracks, or fails, the remix shaft stops turning — concrete can stiffen in the hopper, clog the intake, and stall the entire pumping operation. Replacing it with the correct OEM part restores full agitation function and protects the pump from the downstream damage a blockage can cause.
