The Wacker Neuson is a genuine OEM Hatz 2G40 Engine designed for the DFS 2075HLS diesel walk-behind floor saw. Sourced directly from Wacker Neuson's authorized parts supply, this engine assembly is the exact unit specified for this machine at the factory. As a genuine OEM component, the carries the same part number and build specification as the engine originally fitted to the DFS 2075HLS, so you can be confident in fit and function from the moment it arrives.
Key Features
- Genuine OEM Engine Assembly — Identical in specification to the original Hatz 2G40 unit, ensuring correct power output, mounting geometry, and accessory drive alignment for the DFS 2075HLS.
- Direct Drop-In Replacement — Engineered to match the original engine cradle, fuel connections, and PTO interface on the DFS 2075HLS walk-behind saw without adaptation.
- Confirmed DFS 2075HLS Fitment — Verified for the DFS 2075HLS diesel walk-behind floor saw; always cross-reference your machine's serial number before ordering.
- Sustained Cutting Power — A properly functioning Hatz 2G40 delivers consistent torque to the blade drive, supporting steady depth and speed control through concrete, asphalt, and masonry cuts.
- Fuel System Integrity — As a complete engine assembly, all internal fuel, lubrication, and combustion components are matched and balanced, supporting clean starts and stable running under load.
The Hatz 2G40 is a single-cylinder diesel engine that serves as the primary power source for the DFS 2075HLS walk-behind floor saw, driving the blade spindle through the machine's belt and clutch drive system. It delivers the torque needed to maintain consistent blade speed when cutting hard surfaces such as concrete and asphalt. When the engine degrades or fails — through worn internal components, seized bearings, or chronic starting issues — cutting performance drops and the machine becomes unreliable on site; replacing it with the correct Wacker Neuson 5000128354 assembly restores full operational capacity.
