The Wacker Neuson Exhaust Manifold is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a direct OEM replacement sourced through the Wacker Neuson parts program, the is manufactured to the same specifications as the original, ensuring a correct installation with no guesswork on fit or compatibility. This manifold is confirmed to fit both the RD27-100 and RD27-120 tandem roller configurations, making it a straightforward drop-in replacement when servicing either machine.
Key Features
- Genuine OEM Construction — Cast to the original material grade and port geometry, delivering the exhaust gas flow characteristics the RD27 engine was engineered around.
- Direct Bolt-On Replacement — Matches the original mounting flange pattern and port spacing on the RD27-100 and RD27-120, so installation aligns with existing hardware and gasket surfaces.
- Confirmed RD27 Series Fitment — Verified for the RD27-100 and RD27-120 hydrostatic vibratory rollers, covering both machine configurations in this tandem roller series.
- Restores Proper Engine Exhaust Scavenging — A cracked or warped manifold causes exhaust backpressure, power loss, and rough running; replacing it with the correct OEM part brings engine performance back to spec.
- Exhaust Integrity and Operator Safety — A failed manifold can allow exhaust gases to escape into the engine compartment. Replacing a damaged unit promptly with a genuine part maintains safe operating conditions for the operator and surrounding crew.
The exhaust manifold collects burned gases from each cylinder and routes them out of the engine through the exhaust system. It must maintain a sealed connection at both the cylinder head and the downstream exhaust outlet to keep combustion gases moving efficiently away from the engine. When a manifold cracks, warps, or develops a leak at its mounting face, exhaust gases escape before they reach the outlet, which causes increased engine noise, a noticeable loss of power, and potential heat damage to nearby components. Replacing a compromised manifold restores proper exhaust flow and protects the engine and surrounding hardware from the effects of an uncontrolled exhaust leak.
