The Wacker Neuson Exhaust Manifold is a genuine OEM component designed for the RD12-90 tandem roller series. As a direct factory replacement, it is engineered to the same specifications as the original part and fits both the RD12-90 with Solid ROPS and the RD12-90 with Foldable ROPS configurations. Sourcing a genuine OEM exhaust manifold means you get the correct port geometry, flange dimensions, and material grade — no guesswork, no fitment risk. Verify your machine's part number against before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Cast to the original Wacker Neuson specification, ensuring correct wall thickness and heat-resistant material grade for sustained exhaust temperatures on the RD12-90 engine.
- Direct Bolt-On Replacement — Flange bolt pattern and port spacing match the original manifold exactly, allowing straightforward removal and reinstallation without custom adapters or machining.
- Confirmed RD12-90 Fitment — Compatible with both the Solid ROPS and Foldable ROPS variants of the RD12-90 tandem roller, covering a wide range of machine configurations in this series.
- Maintains Proper Exhaust Scavenging — A correctly sealed and undamaged manifold preserves engine backpressure balance and exhaust flow, supporting fuel efficiency and consistent engine output on demanding asphalt and soil compaction passes.
- Leak and Crack Resistance — Cracked or warped manifolds allow hot exhaust gases to escape before the muffler, creating a fire and burn hazard for operators and nearby components — replacing with a genuine part restores safe exhaust routing.
The exhaust manifold collects spent combustion gases from each cylinder of the engine and channels them into a single outlet toward the muffler and exhaust pipe. It must withstand extreme heat cycling every time the machine starts and shuts down, which makes it susceptible to cracking or warping over time. A failed or leaking manifold not only reduces engine efficiency but can expose operators and fuel or hydraulic lines to dangerously high exhaust temperatures.
