The Multiquip 04005101 Exhaust Valve is a genuine OEM component designed for MVH502DSB2 and MVH502DSB reversible plate compactors, the MDR-9D power trowel, and the MQ41TDH trash pump. As a direct OEM replacement, this valve is manufactured to the same specifications as the original part, ensuring a proper fit within the engine's valve train without additional modification. Sourced directly through authorized Multiquip supply channels, the part is the correct service replacement when your engine shows signs of exhaust valve wear, burnout, or loss of compression. Verify your model code before ordering to confirm compatibility across this multi-family fitment range.
Key Features
- OEM Valve Material and Geometry — Manufactured to original equipment specifications, maintaining the correct head diameter, stem dimensions, and heat-resistant alloy grade required for proper combustion sealing.
- Drop-In Engine Fit — Designed to seat directly into the engine's exhaust port without recutting valve seats or adjusting valve lash beyond standard service procedure.
- Broad Model Compatibility — Fits MVH502DSB2, MVH502DSB, MDR-9D, and MQ41TDH, covering reversible plate compactor, power trowel, and trash pump applications from a single part number.
- Compression and Combustion Integrity — A correctly seated exhaust valve maintains cylinder compression and allows complete scavenging of combustion gases, directly supporting engine power output and fuel efficiency.
- Critical Fuel System Safety — A burned or improperly sealing exhaust valve can cause backfiring, raw fuel bypass, and potential ignition hazards — replacing with a genuine OEM valve restores safe operating conditions.
The exhaust valve sits in the cylinder head and seals the exhaust port during the compression and power strokes, then opens to allow spent combustion gases to exit the cylinder. When the valve face or seat wears, burns, or loses its seal, compression drops, power output falls, and the engine may run rough, overheat, or fail to start. Replacing a worn exhaust valve with the correct OEM part — such as the Multiquip 04005101 — restores proper cylinder pressure and keeps the engine running at its rated output across compactor, trowel, and pump applications.
