The Multiquip 49531 Engine G40 EPA is a genuine OEM engine assembly designed for Multiquip RAMMAX walk-behind rollers, including the RW1404, RW1404MR, RW1504HF, and P33/24 HHMR-BD series. As a direct OEM replacement sourced from Multiquip, part 49531 is built to the same specification as the original unit it replaces, ensuring the engine output, mounting configuration, and emissions compliance align with what these machines left the factory with. Please note that this part carries an NLA (No Longer Available) status — verify current availability with DHS Equipment before placing your order. Fitment applies to RW1404MR units at serial number 326075 and above, RW1504HF units up to serial number, and P33/24 HHMR-BD with blade configurations.
Key Features
- Genuine OEM Engine Assembly — Sourced directly from Multiquip, this G40 EPA engine meets the original combustion, torque, and emissions output specifications required by these roller models.
- EPA-Compliant Power Plant — The G40 EPA designation confirms this engine meets Environmental Protection Agency emissions standards, keeping roller operations in compliance on regulated worksites.
- Serial Number-Specific Fitment — Confirmed for RW1404MR (S/N 326075 and up), RW1504HF (up to S/N 1534188), RW1404, and P33/24 HHMR-BD with blade — always verify your serial number before ordering.
- Drop-In Engine Replacement — Engineered to the same mounting footprint and interface as the original, allowing a straightforward engine swap without custom fabrication or bracket modification.
- Restores Full Compaction Performance — A worn or seized engine on a walk-behind roller results in loss of drum drive and vibratory output; replacing with the correct OEM unit brings the machine back to rated compaction capacity.
- NLA Status — Act on Availability — Part 49531 is designated No Longer Available from Multiquip; stock is limited and sourcing windows for discontinued OEM engine assemblies can close without notice.
The G40 EPA engine serves as the primary power source for the roller's drum drive and, where applicable, the vibratory system. It converts fuel into the mechanical energy that propels the drum and generates the compactive force needed to achieve proper material density on asphalt and granular base layers. When this engine deteriorates or fails entirely — through wear, fuel system breakdown, or loss of compression — the roller loses the ability to drive or vibrate the drum, halting compaction work until the engine is replaced with a correctly specified unit.
