The Wacker Neuson Intake Valve is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 walk-behind concrete power trowels, BFS floor saws, PT3A trash pumps, GV and HPG series power units, and BPU reversible vibratory plate compactors. As a direct factory part, the meets the exact tolerances and material specifications required by the engine assemblies used across these machine families. Confirm your model number before ordering — this valve serves an extensive fitment list spanning multiple product lines. Cross-reference your machine's model and serial number to ensure the is the correct intake valve for your application.
Key Features
- Genuine OEM Valve Integrity — Manufactured to Wacker Neuson's exact stem diameter, head geometry, and material hardness specifications to maintain proper sealing and airflow through the engine's intake port.
- Direct Engine Drop-In — Engineered to seat correctly in the valve guide and mate flush with the cylinder head, allowing straightforward installation without recutting or shimming.
- Broad Cross-Equipment Fitment — Compatible with CT36 and CT48 concrete trowels, BFS940 and BFS935/914 floor saws, PT3A trash pumps, BPU 3050/4045 reversible plate compactors, and GV/HPG power units, among others.
- Restored Compression and Throttle Response — A worn or pitted intake valve allows combustion gases to leak past the seat, robbing the engine of compression, increasing fuel consumption, and causing rough running or hard starts. A fresh OEM valve restores the tight seal that proper engine performance depends on.
- Fuel System Safety Compliance — Correct valve seating is critical to preventing unburned fuel from entering the crankcase; using the specified OEM part supports safe engine operation across all listed machines.
The intake valve controls the flow of the air-fuel mixture into the engine's combustion chamber, opening on the intake stroke to admit the charge and closing tightly during compression and combustion to contain cylinder pressure. When the valve face or seat wears, burns, or develops pitting, the seal is compromised — compression drops, the engine loses power, and fuel efficiency suffers noticeably. Replacing a failed intake valve with the correct OEM part restores the combustion seal and returns the engine to its designed output, keeping concrete trowels, floor saws, pumps, and compactors running at full capability.
