The Multiquip 27933401H3 Intake Valve is a genuine OEM component designed for B46S90 series walk-behind power trowels. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring correct fitment and consistent engine performance on B46S90 equipment. Sourced through DHS Equipment as an authorized Multiquip parts distributor, this intake valve ships as the exact component your machine was built with.
Key Features
- OEM-Spec Valve Geometry — Manufactured to the original seat angle, stem diameter, and head dimensions so the valve seals correctly against the cylinder head on the first install.
- Direct Drop-In Replacement — Matches the original valve's stem length and keeper groove configuration, allowing straightforward installation without machining or adjustment.
- Confirmed B46S90 Fitment — Verified for Whiteman walk-behind power trowel B46S90 series — use part number 27933401H3 to confirm compatibility before ordering.
- Restores Full Compression — A worn or burned intake valve causes compression loss, rough running, and hard starting; installing a fresh OEM valve restores proper cylinder pressure and smooth operation.
- Fuel Efficiency Protection — A correctly seating intake valve ensures the proper air-fuel charge enters the combustion chamber, preventing rich-running conditions and excess fuel consumption.
The intake valve controls the flow of the air-fuel mixture from the carburetor into the engine's combustion chamber. It opens on the intake stroke to allow the charge in, then seats tightly to seal the chamber during compression and combustion. When an intake valve wears, burns, or loses its seat seal, compression drops, the engine becomes difficult to start, power output falls off, and fuel consumption rises. Replacing a damaged intake valve with a genuine OEM part restores proper compression, combustion efficiency, and engine response — keeping the trowel running at full working capacity.
