The Multiquip 2791 Head Gasket is a genuine OEM replacement designed for B46S90 walk-behind power trowels. As a direct OEM component sourced through Multiquip's authorized parts network, it is manufactured to the exact specifications required by the B46S90 — ensuring a correct, leak-free seal between the cylinder head and engine block. DHS Equipment supplies this part to keep your trowel performing at full capacity with no guesswork on fit or compatibility.
Key Features
- OEM-Grade Sealing Material — Engineered to the precise compression and heat-resistance requirements of the B46S90 engine, delivering a consistent, durable seal under operating conditions.
- Drop-In Replacement — Matches the original head gasket dimensions exactly, seating correctly against the cylinder head and block mating surfaces without any modification.
- Confirmed Fitment for B46S90 — Verified compatibility with the Whiteman B46S90 walk-behind power trowel series, so you can order with confidence.
- Prevents Coolant and Compression Loss — A properly seated head gasket maintains cylinder compression and prevents combustion gases or fluids from escaping, keeping the engine running at full power.
- Fuel System and Engine Safety — A failed head gasket can allow combustion gases to contaminate the oil system or cause overheating; replacing it promptly protects the entire engine assembly.
The head gasket forms a critical seal between the cylinder head and the engine block, containing combustion pressure and preventing oil or coolant from leaking into the combustion chamber. When a head gasket fails, the engine can lose compression, overheat, or suffer internal contamination — leading to significant engine damage if left unaddressed. Replacing a worn or blown head gasket with a genuine OEM part like the Multiquip 2791 restores proper sealing and protects the engine's long-term integrity.
