The Wacker Neuson Intake Manifold is a genuine OEM component designed for the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Power Trowel series, BFS 2020AS Saw, and GS12Ai. As a factory-sourced part, meets the exact engineering tolerances Wacker Neuson specifies for these machines, so you can install it with confidence and get back to work. Fitment covers multiple configurations within the RD12A-90 family — including the foldable ROPS variant — as well as standard and wheel-kit-equipped trowel models, making this a versatile OEM replacement across a broad range of Wacker Neuson equipment.
Key Features
- OEM Port Geometry and Sealing Surfaces — Manufactured to Wacker Neuson's original specifications, ensuring correct air-fuel mixture flow and a leak-free mating surface with the carburetor and cylinder head.
- Direct-Fit Replacement — Matches the original mounting bolt pattern and port dimensions, dropping straight in without machining or adapters.
- Broad Model Coverage — A single part number covers the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Power Trowel series, BFS 2020AS Saw, and GS12Ai, consolidating your parts inventory.
- Protects Engine Breathing Efficiency — A correctly sealed intake manifold keeps the air-fuel charge consistent; cracks or warping cause lean running, hard starts, and accelerated engine wear.
- Fuel System Integrity — Proper manifold sealing prevents unmetered air from entering the fuel circuit, reducing the risk of engine over-rev and fuel system damage in gas-powered equipment.
The intake manifold is the passage that channels the air-fuel mixture from the carburetor into the engine's combustion chamber. It must form an airtight seal at both the carburetor flange and the cylinder head port — any crack, warp, or deteriorated gasket surface allows unmetered air to enter, leaning out the mixture and causing rough idling, loss of power, or difficulty starting. On compact construction equipment like rollers, trowels, and cut-off saws, where engines run hard under sustained load, a compromised intake manifold can accelerate wear and lead to costly engine repairs if not addressed promptly.
