The Wacker Neuson 5100037228 Hatz Engine is a genuine OEM power unit designed for RD7 and RD7H walk-behind tandem rollers. As a direct factory replacement, this engine is sourced from Wacker Neuson's authorized supply chain, ensuring it meets the exact specifications of the original unit installed at the factory. Fitment covers multiple RD7 and RD7H configurations, so confirm your machine number before ordering to ensure a correct match. When your tandem roller needs a full engine replacement, part number 5100037228 is the factory-specified solution.
Key Features
- Genuine OEM Power Source — Factory-supplied Hatz diesel engine built to the exact output, mounting, and interface specifications required by the RD7 and RD7H tandem roller platform.
- Direct Drop-In Replacement — Engineered to match the original engine's mounting footprint, drive coupling, and ancillary connections, supporting a straightforward swap without custom fabrication.
- Confirmed RD7 and RD7H Fitment — Verified compatibility across RD7 Tandem Roller and RD7H variants; cross-reference your machine number to confirm the correct configuration for your unit.
- Full Compaction Performance Restored — A correctly specified engine delivers the rated drum frequency and travel speed the RD7 platform depends on for consistent asphalt and soil compaction results.
- Fuel System Integrity — As the primary fuel-consuming component, a properly matched OEM engine ensures correct fuel delivery, combustion efficiency, and emissions compliance for the machine's rated duty cycle.
The engine is the core power source for the RD7 and RD7H tandem roller, driving both the exciter system that generates vibratory compaction force and the hydraulic circuit that controls drum travel and steering. On a tandem roller, consistent engine output directly determines drum amplitude and compaction depth, so a worn or failed engine leads to uneven compaction, reduced productivity, and potential surface defects in asphalt finishing work. Replacing a failed engine with the correct OEM unit restores the machine to its rated operating parameters and gets the roller back to producing consistent, specification-compliant compaction passes.
