The Wacker Neuson Core Plug is a genuine OEM component designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. Sourced directly from Wacker Neuson, this plug meets the exact material and dimensional standards specified for these tandem roller models. It is a direct-fit replacement that installs in the same position as the original, with no adaptation needed. Whether you are performing scheduled maintenance or addressing a coolant or oil leak, the is the correct part to restore your machine to proper operating condition.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's precise interference-fit specification, ensuring the plug seats and seals correctly in the bore without distortion or weepage.
- Direct Replacement for RD27 Series — Confirmed fit for RD27-100 and RD27-120 Hydrostatic Vibratory Rollers; installs in the original bore location as a like-for-like swap.
- Correct Material Grade — Produced from the same material alloy as the factory original, matching the thermal expansion and corrosion-resistance requirements of the engine or drivetrain cavity it seals.
- Prevents Fluid Loss — A properly seated core plug maintains internal fluid pressure and prevents coolant or oil escape that can lead to overheating or lubrication failure in the roller's drivetrain or engine block.
- Verified Part Number — Part number 5000161159 is confirmed against Wacker Neuson's official parts documentation for the RD27-100 and RD27-120, giving you confidence before the part ships.
A core plug — sometimes called a freeze plug or expansion plug — is a pressed-in metal disc that seals casting voids left in an engine block or drivetrain housing during the manufacturing process. It holds internal fluids in place and, in engine applications, is also designed to displace outward under extreme freezing pressure to protect the casting from cracking. When a core plug corrodes, loosens, or is dislodged, the affected system loses fluid rapidly, which can cause overheating or lubrication failure and bring the machine to a halt. Replacing a failed plug promptly with the correct OEM part restores the sealed system and protects the surrounding castings from further damage.
