The Wacker Neuson Valve Stem Seal is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including the RD12A-90 tandem roller series, CRT36-26A and CRTv36-26A power trowels, BFS 2020AS saw, GS12Ai screed, and GPS9700A generator. As a direct factory part, the is manufactured to the same specification as the original seal installed at production — ensuring a consistent, properly fitted replacement every time. This seal is confirmed compatible across multiple machine types within the Wacker Neuson lineup, making it a practical stock item for service teams running mixed fleets.
Key Features
- Genuine OEM Sealing Material — Manufactured to Wacker Neuson's original compound and dimensional specification, delivering the same compression characteristics as the factory-installed seal.
- Drop-In Valve Stem Fit — Engineered to seat directly onto the valve stem without modification, maintaining the correct interference fit for an airtight installation.
- Wide Fleet Coverage — A single part number covers the RD12A-90 roller series, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai screed, and GPS9700A generator.
- Prevents Oil Consumption and Contamination — A intact valve stem seal keeps engine oil out of the combustion chamber; a worn seal leads to blue exhaust smoke, fouled plugs, and accelerating engine wear.
- Emissions and Engine Compliance — A properly sealing valve stem seal is essential for maintaining correct combustion conditions and keeping exhaust emissions within acceptable operating limits.
A valve stem seal fits over the valve stem inside the cylinder head and controls the thin film of oil that lubricates the valve guide. It acts as a metered barrier — allowing just enough oil to lubricate the stem while preventing excess oil from being drawn into the combustion chamber during the intake stroke. When the seal hardens, cracks, or loses its grip, oil migrates past the valve stem and burns with the fuel charge, producing visible smoke, increasing oil consumption, and leaving carbon deposits on valves and piston crowns. Replacing a worn valve stem seal promptly protects the rest of the valve train and keeps the engine running cleanly.
