The Multiquip EH340YS2301 Engine Robin Tapered GA-6RZII is a genuine OEM replacement engine built for the GA-6RZ concrete pump. As a direct OEM component sourced through Multiquip's authorized parts network, this engine is built to match the original unit installed at the factory — ensuring correct shaft taper, mounting configuration, and output characteristics for the GA-6RZ. When your pump's powerplant fails or reaches end of service life, replacing it with the correct OEM engine keeps the machine performing at its intended capacity without compromise.
Key Features
- OEM-Matched Power Output — Genuine Multiquip OEM engine matched to the exact horsepower and torque specification of the original Robin unit installed in the GA-6RZ.
- Tapered Shaft Configuration — Features the correct tapered shaft profile required by the GA-6RZ drive system, ensuring proper power transfer to the pump assembly without adaptation.
- Confirmed GA-6RZ Fitment — Engineered specifically for the Multiquip GA-6RZ concrete pump series; verify by model code before ordering.
- Restored Pumping Capacity — A correctly matched engine restores full concrete output volume and pressure — a worn or underpowered engine reduces throughput and strains downstream components.
- Fuel System Integrity — OEM Robin engine includes factory-configured carburetion and ignition components, eliminating the guesswork of mismatched fuel delivery that can cause hard starts or rough running in concrete pump applications.
The engine is the primary power source for the GA-6RZ concrete pump, converting fuel into rotational force that drives the pump's cycloidal or piston mechanism to move concrete through the delivery line. When an engine loses compression, develops fuel delivery problems, or fails outright, concrete placement stops entirely — making a correct, purpose-matched replacement critical. The Robin tapered-shaft design on this unit is specific to how the GA-6RZ couples engine power to the pump drive, so using the correct replacement engine, EH340YS2301, preserves that mechanical interface and restores the machine to full working condition.
