Key Features
- OEM Exhaust Integrity — Manufactured to the original casting and dimensional tolerances, so exhaust gases are routed correctly without gaps, leaks, or warping at the joint.
- Direct-Mount Replacement — Bolt pattern, port dimensions, and mounting geometry match the original arm, allowing straightforward installation on compatible models.
- Wide Fitment Coverage — Compatible with MT-76D2, MT-86D, MT-86D2, MVC98D2, MVH-150D, MVH-150D2, MVH150VD2, MVH-200DA, MVH-306D, MVH-306DS, and QP3TY equipment.
- Sustained Engine Performance — A sound exhaust arm maintains proper back-pressure and exhaust flow; a cracked or warped arm causes rough running, power loss, and accelerated engine wear.
- Heat and Vibration Resistance — Built to withstand the thermal cycling and high-frequency vibration inherent to rammer and compactor operation, where exhaust components face constant mechanical stress.
The exhaust arm assembly channels combustion gases from the engine's exhaust port away from the machine and its operator. It forms a critical link in the exhaust path — connecting the engine output to the muffler or exhaust outlet — and must maintain a sealed, structurally sound connection to keep exhaust flow consistent. When this arm cracks, corrodes, or works loose, exhaust gases can escape into the machine's operating environment, causing rough idling, reduced engine output, excessive heat buildup near the powerhead, and potential exposure hazards for the operator. Replacing a worn exhaust arm assembly promptly restores proper exhaust routing and protects both engine longevity and operator safety.
