The Multiquip 05420 Engine Tub is a genuine OEM component designed for RAMMAX walk-behind roller models including the RW1404MR, RW1504HF, and P33/24 series. As a direct OEM replacement, it is manufactured to the same standards as the original part installed at the factory, ensuring a correct, hassle-free installation. Fitment covers RW1404MR units both up to and from S/N 326075, RW1504HF units up to S/N, and P33/24 HHMR-BD configurations with blade. Always verify your model and serial number before ordering to confirm compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the original equipment specification, so the tub seats, aligns, and mounts exactly as the factory-installed component did.
- Structural Housing Integrity — Provides the correct rigid enclosure for the engine assembly, protecting internal components from debris, vibration stress, and environmental exposure during compaction work.
- Broad RAMMAX Roller Fitment — Confirmed for RW1404MR, RW1504HF, and P33/24 HHMR-BD walk-behind roller models across multiple serial number ranges.
- Drop-In Replacement — Matches the original mounting points and geometry, so no fabrication or modification is needed to complete the swap.
- Supports Engine System Stability — A cracked or damaged engine tub can allow excessive engine movement and accelerate wear on mounts, fuel lines, and surrounding components; replacing it restores proper engine retention.
The engine tub is the structural housing that surrounds and secures the engine assembly within the roller frame. It holds the powerplant in its correct position, shields it from dirt and impact, and provides the mounting structure for related components such as engine mounts and fuel system elements. When the tub is cracked, bent, or otherwise compromised, the engine loses stable support, which can lead to accelerated wear on mounts, vibration in connected systems, and potential damage to the engine itself.
