The Wacker Neuson is a genuine OEM 3/4 Expansion Plug designed for RD12, RD16, and CB14B series tandem rollers and soil and asphalt compaction equipment. As a factory-sourced component, it is manufactured to the exact dimensions and material specifications required by Wacker Neuson, ensuring a correct, leak-free installation every time. This plug fits a broad range of machine configurations across the RD12A-90, RD12-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 series. Keeping the correct expansion plug installed protects internal passages and maintains the integrity of fluid or pressure systems within these machines.
Key Features
- Exact OEM Dimensions — Manufactured to precise 3/4 thread or bore sizing, ensuring a flush, pressure-retaining seal without reworking the bore or mating surface.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000163368 meets the same material and tolerance standards as the original installed component.
- Broad Tandem Roller and Compactor Fitment — Confirmed fitment across RD12-90, RD12A-90, RD16-90, RD16-100, CB14B-900, and CB14B-1000 series machines, covering multiple machine numbers and ROPS configurations.
- Seals Internal Passages Securely — A properly seated expansion plug prevents fluid seepage from galleries and housings; a failed or missing plug can lead to fluid loss, contamination ingress, or pressure drop affecting machine operation.
- Direct Swap Installation — Pressed or threaded into its bore using standard tooling, the 5000163368 replaces the original plug without machining or adaptation to the housing.
An expansion plug is a small but critical sealing component used to close off machined passages, galleries, or ports within an engine block, hydraulic housing, or drivetrain casing. It holds internal fluids under pressure within their intended circuits and prevents contamination from entering open bores. When an expansion plug corrodes, works loose, or is damaged during service, the result is typically an external fluid leak or a loss of pressure within the affected circuit — both of which can cause accelerated wear or operational failure if left unaddressed. Replacing a failed plug promptly with the correct OEM part restores the sealed integrity of the system.
