The Wacker Neuson Fuel Injection Pump is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers. As a direct OEM replacement sourced through Wacker Neuson's authorized parts network, this pump is built to the exact specifications of the original unit installed at the factory. Verified fitment covers both the RD27-100 and RD27-120 roller models, so you can order with confidence knowing this part is engineered for your machine.
Key Features
- OEM-Matched Fuel Metering: — Manufactured to the same delivery pressure and timing tolerances as the original, ensuring the engine receives the precise fuel charge it requires at every RPM.
- Drop-In Fitment for RD27 Series Rollers: — Engineered to mount and connect exactly as the factory pump does on RD27-100 and RD27-120 hydrostatic vibratory tandem rollers, with no adaptation needed.
- Genuine Wacker Neuson OEM Part: — Carrying part number 5000161387, this is an authentic replacement backed by Wacker Neuson's OEM quality standards — not an approximation.
- Sustained Engine Output on the Drum: — A properly functioning injection pump maintains consistent power delivery to the drive and vibration systems, keeping compaction performance stable across asphalt and soil passes.
- Fuel System Integrity: — A worn or failing injection pump can cause hard starting, uneven engine load, and increased exhaust emissions — replacing it with the correct OEM unit restores clean, controlled combustion.
The fuel injection pump is responsible for drawing diesel fuel from the tank and delivering it under high pressure to the engine's injectors at precisely timed intervals. Consistent injection pressure and timing are critical to clean combustion, stable power output, and efficient fuel consumption — all of which directly affect how the RD27 roller performs during compaction passes. When the pump degrades, symptoms such as rough idling, loss of engine power, difficult cold starts, and excessive smoke typically follow, making prompt replacement essential to keeping the machine productive.
