The Multiquip 593089 is a genuine OEM Exhaust Manifold B46B90 designed for the B46B90 walk-behind power trowel. Sourced directly from Multiquip, this part meets the same specifications as the original component installed at the factory. The 593089 is a direct replacement for B46B90 series trowels, ensuring a correct, bolt-on fit without guesswork. Keeping the exhaust manifold in proper working order is essential to engine performance and safe operation on any concrete finishing job.
Key Features
- Genuine OEM Exhaust Integrity — Manufactured to the same material and dimensional standards as the original manifold, ensuring proper exhaust gas sealing and heat resistance specific to this engine application.
- Direct Bolt-On Replacement — Matches the original mounting pattern and port dimensions of the B46B90, allowing straightforward installation with existing hardware.
- Confirmed B46B90 Fitment — Verified for the Multiquip B46B90 walk-behind power trowel series; always confirm part number 593089 against your machine's parts manual before ordering.
- Sustained Engine Output — A sound exhaust manifold maintains correct back-pressure and prevents exhaust leaks that can cause power loss, rough running, or overheating during extended troweling operations.
- Operational Safety — A cracked or leaking manifold can direct hot exhaust gases toward fuel lines, wiring, or the operator — replacing a failed manifold promptly is a genuine safety measure on any jobsite.
The exhaust manifold collects spent combustion gases from the engine's cylinder head and routes them into the exhaust system and away from the machine. It must withstand extreme heat cycling and mechanical vibration while maintaining a gas-tight seal at every joint. When an exhaust manifold cracks, warps, or develops a leak, the engine loses efficiency, exhaust fumes can escape near the operator and fuel components, and the machine may run rough or overheat — making timely replacement critical to both performance and safety.
