The Multiquip 03997100 is a genuine OEM Exhaust Tube designed for MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D series equipment. As a direct OEM replacement, this part is sourced from Multiquip to deliver the exact fit and function required to keep your equipment running as intended. Confirmed fitment covers the MVH502DSB and MVH502DSB2 reversible plate compactors, the MQ41TDH trash pump, and the MDR-9D ride-on trowel. When your original exhaust tube shows signs of cracking, corrosion, or exhaust leaks, replacing it promptly with part 03997100 restores proper engine ventilation and protects surrounding components.
Key Features
- OEM-Matched Exhaust Routing — Manufactured to the same dimensional and material specifications as the original, ensuring correct exhaust gas flow path without gaps or leaks at connection points.
- Direct Drop-In Replacement — Engineered to align with existing mounting points and exhaust port interfaces on compatible models, requiring no cutting or modification to the exhaust assembly.
- Broad Model Coverage — Fits the MVH502DSB and MVH502DSB2 reversible plate compactors, MQ41TDH trash pump, and MDR-9D ride-on trowel — one part across multiple equipment types.
- Exhaust Integrity Restored — A failed or leaking exhaust tube allows hot gases to escape near fuel lines, filters, and seals; replacing with a properly fitted tube eliminates this risk and restores clean exhaust routing.
- Fuel and Heat System Compliance — Correct exhaust tube fitment is critical in fuel-adjacent systems; using the proper OEM part maintains safe operating temperatures and protects surrounding components from heat damage.
The exhaust tube channels combustion gases from the engine's exhaust port away from the machine and its operator. It serves as the primary conduit in the exhaust system, directing hot gases through a controlled path to prevent heat buildup around engine components, fuel systems, and vibration-sensitive parts. When the exhaust tube cracks, corrodes, or develops a poor seal at its joints, exhaust gases can escape into unintended areas — raising operating temperatures, creating potential fire hazards near fuel components, and causing the engine to run less efficiently. Replacing a damaged tube with the correct OEM part restores the intended exhaust flow path and protects the machine's surrounding systems.
