The Wacker Neuson is a genuine OEM GX160-UT2-QC-9-OH Gas Engine designed for the WP1540A, WP1540Aw, WP1550A, and WP1550Aw single-direction vibratory plate compactors. As a factory-sourced replacement, this engine is built to the exact configuration your machine left the production line with — ensuring a correct, no-compromise installation. This is the same GX160-UT2-QC-9-OH Gas Engine that powers these WP-series plates from the factory, covering US-spec and Sunbelt-variant machines alike. If your plate compactor has lost power, burns oil, or the existing engine is beyond repair, part number is the correct direct replacement to restore full compaction output.
Key Features
- OEM Engine Specification Match — Sourced directly from Wacker Neuson, this engine ships in the exact GX160-UT2-QC-9-OH configuration specified for the WP1540A and WP1550A families, including the correct output shaft, throttle linkage, and mounting bolt pattern.
- Direct Drop-In Fitment — Engineered to mount directly onto the WP1540A, WP1540Aw, WP1550A, and WP1550Aw compactor frames without reworking the engine deck or drive train connections.
- Covers US-Spec and Sunbelt Variants — Verified fitment across multiple machine numbers, including the Vibroplate WP1550Aw Sunbelt variant, so you can order with confidence regardless of which WP-series unit you're servicing.
- Full Compaction Power Restored — A worn or seized engine robs the exciter assembly of the consistent RPM it needs to deliver rated compaction force. Replacing with 5100046324 brings centrifugal force output back to rated spec, keeping base prep and paving stone work on schedule.
- Fuel System Integrity — As a complete engine assembly, this unit includes the carburetor and fuel system components pre-configured for the GX160-UT2-QC-9-OH spec, eliminating the risk of mismatched fuel delivery that can accompany piecemeal repairs.
The gas engine is the power source for the entire vibratory plate compactor — it drives the eccentric shaft inside the exciter housing to generate the rapid vibrations that compact soil, aggregate, and paving stone base layers. On WP-series plates, consistent engine RPM is critical: too low and the plate loses compaction force; an engine that surges or stalls creates uneven density in the base material. When the engine wears out or sustains internal damage, the only reliable path back to rated performance is a full engine replacement with the correct OEM unit. The Wacker Neuson 5100046324 GX160-UT2-QC-9-OH Gas Engine delivers exactly that — restoring the steady, high-RPM output these compactors depend on.
