Sourced directly from Multiquip, this assembly meets the original engineering specifications for the LS300, ensuring a correct, dependable fit without guesswork. Keeping the torsion bar shaft in good working condition is critical to maintaining consistent pumping action and protecting surrounding drivetrain components from accelerated wear.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional tolerances specified for the LS300 pumping system, delivering the structural integrity this high-stress component demands.
- Direct Assembly Replacement — Supplied as a complete shaft assembly, allowing straightforward installation into the existing pump configuration without sourcing individual sub-components separately.
- LS300 Confirmed Fitment — Engineered specifically for the Multiquip LS300 hydraulic-driven concrete pump; verify your model code before ordering to ensure compatibility.
- Sustained Pump Output — A correctly functioning torsion bar shaft maintains the mechanical timing and force transfer needed for steady, uninterrupted concrete delivery on the pour.
- Verified Multiquip Part Number — Ordering by OEM part number EM516931 eliminates the risk of receiving an incorrect part, protecting your investment and your schedule.
The torsion bar shaft assembly in a hydraulic concrete pump serves as a key mechanical link in transferring and absorbing torsional forces generated during the pumping cycle. It works to maintain consistent rotational alignment and reduce shock loading on adjacent drivetrain components, allowing the pump to deliver concrete smoothly under continuous operating pressure. When this assembly becomes worn, cracked, or fails entirely, the pump can lose output consistency, cause increased vibration, or place damaging stress on connected components — making timely replacement essential to keeping the LS300 running at full capacity.
