The Multiquip EM16814 Tensioner is a genuine OEM component designed for LS-series hydraulic-driven concrete pumps, including the LS300, LS400, LS500, LS40TD, LS50TD, LS60TD, LS40D, LS600, LS300P, LS600P, LS300G, and LS300GK. Sourced directly from Multiquip, this tensioner is engineered to the exact specification of the original part, ensuring a direct installation fit with no guesswork. Confirmed fitment spans the full Mayco LS pump lineup, making EM16814 the correct choice for operators running any of these concrete pump models.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the tensioner maintains correct belt load and engagement across the LS-series drive system.
- Direct Installation Fit — Matches the original mounting points and geometry of the LS-series pump drivetrain, dropping into place as a straightforward swap.
- Broad LS-Series Compatibility — Verified for LS300, LS400, LS500, LS40TD, LS50TD, LS60TD, LS40D, LS600, LS300P, LS600P, LS300G, and LS300GK concrete pump models.
- Consistent Belt Tension — A properly functioning tensioner maintains the drive belt at the correct operating load, preserving pump output and preventing premature belt wear or slippage.
- Protects Downstream Components — Correct tension prevents belt-related stress on pulleys, bearings, and the hydraulic drive system — a worn tensioner left in service can accelerate wear across multiple components.
The tensioner on an LS-series concrete pump maintains constant, controlled pressure on the drive belt, keeping it properly engaged with the pulleys throughout operation. Without correct tension, the belt can slip, reducing hydraulic drive efficiency and causing inconsistent pump output. A worn or failed tensioner will often produce audible belt noise, vibration, or erratic pump performance — replacing it promptly with a genuine OEM part like the EM16814 restores proper drive function and protects the surrounding drivetrain components from secondary wear.
