The Multiquip 18310ZDJ000 Muffler Complete is a genuine OEM exhaust assembly designed for MTX70HDR and MTX80HDR rammers. Sourced directly through Multiquip's authorized parts program, this muffler is built to the exact specifications of the GXR120RTKRB6 engine fitted to these machines. The 18310ZDJ000 drops into place as a direct OEM replacement, ensuring correct exhaust routing, mounting alignment, and heat management from the first use. If your rammer is running loud, losing power, or showing signs of exhaust leakage, replacing the muffler with this genuine Multiquip component restores proper operation quickly.
Key Features
- Genuine OEM Exhaust Construction — Manufactured to Multiquip's original exhaust specifications for the GXR120RTKRB6 engine, ensuring correct backpressure and heat dissipation for the MTX rammer platform.
- Direct-Fit Replacement — Matches the original mounting points and exhaust outlet geometry on MTX70HDR and MTX80HDR rammers, so installation is straightforward with no fabrication or adaptation needed.
- Confirmed Fitment for HDR-Series Rammers — Verified for the MTX70HDR and MTX80HDR, Multiquip's GX120-powered, diaphragm-carburetor tamper models.
- Restores Full Engine Output — A cracked or degraded muffler disrupts exhaust flow and can cause the engine to run rough or lose compaction force. This complete assembly returns the rammer to its rated operating performance.
- Exhaust Integrity and Operator Safety — A properly sealed muffler contains exhaust gases and directs them away from the operator. Replacing a failing unit with a genuine OEM muffler maintains safe exhaust routing in line with the machine's original design.
The muffler on a rammer is responsible for receiving hot exhaust gases from the engine's cylinder head, reducing noise to an acceptable operating level, and safely directing exhaust away from the machine and operator. On high-cycle equipment like the MTX70HDR and MTX80HDR, the muffler is subject to constant thermal stress from rapid engine cycling, which can lead to cracking, corrosion, or warping of the exhaust outlet over time. A failed or leaking muffler not only increases noise significantly but can also affect engine efficiency and expose the operator to exhaust gases — making timely replacement with a correct OEM unit like the 18310ZDJ000 an important part of routine rammer maintenance.
