The Multiquip 806665 Drive Coupler Assembly is a genuine OEM component designed for the LS450 hydraulic-driven concrete pump. As a direct OEM replacement, this assembly is built to the same specifications as the original part, ensuring a correct, trouble-free installation on LS450 equipment. DHS Equipment sources this part directly through authorized Multiquip channels so you can order with confidence in its authenticity and fitment accuracy.
Key Features
- Genuine OEM Construction: — Manufactured to original Multiquip tolerances, ensuring the coupling interface engages with correct torque transfer characteristics — critical for a high-demand concrete pump drivetrain.
- Direct-Fit Replacement: — Engineered to install in the same mounting position and orientation as the original, with matching shaft interface dimensions for the LS450 pump assembly.
- Confirmed LS450 Fitment: — Verified for the Multiquip LS450 hydraulic-driven concrete pump; always cross-reference part number 806665 before ordering.
- Sustained Power Transfer: — A functioning drive coupler maintains clean, consistent power delivery from the engine to the pump mechanism; a worn or failed coupler causes slippage, vibration, and loss of output pressure.
- Drivetrain Protection: — The coupler assembly also acts as a mechanical buffer, absorbing shock loads that would otherwise stress the pump's internal hydraulic components and extend their service life.
The drive coupler assembly connects the engine or motor output shaft to the pump's drive mechanism, transmitting rotational power while accommodating minor shaft misalignment and absorbing drivetrain shock. On a concrete pump like the LS450, this component is under constant load and must maintain a secure, vibration-resistant connection to sustain consistent pumping pressure and flow rate. When the coupler wears, cracks, or fails, the result is power loss, erratic pump output, or complete drivetrain disengagement — making timely replacement essential to keeping the machine productive.
