Wacker Neuson 5000189164 Honda GX240 Threaded Engine

The Wacker Neuson Honda GX240 Threaded Engine is a genuine OEM engine assembly designed for the PT3A series 75mm/3-inch centrifugal trash pumps. As a factory-original component, this engine is sourced directly through Wacker Neuson's authorized parts supply chain, ensuring it meets every specification required for correct installation and operation on PT3A models. Confirmed fitment covers the PT3A, PT3A Pump, and 75mm/3-inch Centrifugal Trash Pump variants. When your pump's powerplant needs replacing, the delivers a direct, bolt-in solution with no guesswork on compatibility.

Key Features

• Genuine OEM Engine Assembly — Factory-original Honda GX240 construction ensures correct displacement, torque output, and threaded shaft interface — exactly as Wacker Neuson specifies for PT3A pump operation.
• Threaded Output Shaft — The threaded shaft configuration engages directly with the PT3A pump drive coupling, delivering a secure mechanical connection without adapter hardware.
• Verified PT3A Series Fitment — Confirmed for PT3A, PT3A Pump, and 75mm/3-inch Centrifugal Trash Pump models, covering the full range of current PT3A configurations.
• Full Pump Output Restored — A fresh Honda GX240 brings rated horsepower and consistent RPM back to your pump, maintaining the flow rates and suction lift capacity the PT3A is built to deliver.
• Fuel System Integrity — As a complete engine replacement, all fuel delivery and ignition components are factory-fresh, eliminating the running issues, hard starts, and flooding associated with a worn powerplant.

The Honda GX240 is a four-stroke gasoline engine that serves as the prime mover for the Wacker Neuson PT3A centrifugal trash pump, converting fuel combustion into rotational power that drives the pump impeller. The threaded shaft variant is specifically configured to mate with the pump's drive assembly, transferring engine torque directly to move high volumes of water — including water laden with solids and debris. When the engine loses compression, develops fuel delivery faults, or suffers internal mechanical failure, pump output drops sharply or ceases entirely; replacing the engine unit with a genuine OEM assembly restores full operational capacity.
