The Multiquip 01129000 is a genuine OEM Muffler Hatz 2G40 designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF. As a direct Multiquip OEM component, this muffler is produced to the same specifications as the original unit installed at the factory, ensuring a correct fit on compatible machines. Verified fitment covers RW1404MR units from S/N 326075 and up, as well as RW1504HF units up to S/N. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence that 01129000 is the right part for your machine.
Key Features
- Genuine OEM Exhaust Specification — Manufactured to Multiquip's original exhaust geometry and heat-tolerance rating for the Hatz 2G40 engine, not a generic approximation.
- Direct Bolt-On Replacement — Matches the original mounting flange and outlet configuration of the Hatz 2G40, so installation aligns without rework or adapter hardware.
- Confirmed Fitment for RAMMAX Rollers — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) walk-behind rollers.
- Proper Exhaust Flow Restoration — A correctly functioning muffler maintains exhaust backpressure within the Hatz 2G40's operating range, protecting engine output and fuel efficiency; a cracked or corroded muffler can disrupt both.
- Emission and Noise Compliance — Replacing a failed muffler with the correct OEM unit helps maintain the exhaust noise and emission characteristics the machine was built to meet.
The muffler on a Hatz 2G40-powered roller is responsible for safely directing hot exhaust gases away from the engine and operator while dampening combustion noise to acceptable levels. It also plays a role in maintaining the correct exhaust backpressure that the engine relies on for stable power delivery. When a muffler cracks, corrodes, or develops leaks, exhaust gases can escape in unintended directions, noise levels rise sharply, and engine performance can degrade — making timely replacement important for both operator safety and machine reliability.
