The Multiquip 50302100 Main Bearing 2G40 Hatz is a genuine OEM bearing designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF. Sourced directly from Multiquip, this part meets the original engineering specifications for the Hatz 2G40 engine fitted to these roller models. The 50302100 is a direct-fit replacement that installs exactly as the factory original, keeping your roller engine running within proper tolerances. Confirmed fitment covers RW1404MR units at serial number 326075 and up, and RW1504HF units up to serial number.
Key Features
- Genuine OEM Precision: — Manufactured to the exact tolerancing required by the Hatz 2G40 engine, ensuring proper load distribution and journal contact across the main bearing surface.
- Direct Engine Fitment: — Engineered to seat and align with the Hatz 2G40 engine block without machining or shimming — drops in as the factory original did.
- Confirmed Roller Compatibility: — Fits RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
- Engine Longevity Protection: — A correctly fitted main bearing maintains proper crankshaft support; a worn or failing bearing leads to excessive crankshaft play, oil pressure loss, and accelerated engine damage.
- Backed by Multiquip OEM Sourcing: — Sold as a genuine Multiquip part, giving you full confidence that the specification, material grade, and dimensional accuracy match what came off the assembly line.
The main bearing supports the crankshaft within the engine block, allowing it to rotate smoothly under the loads generated during operation. On a Hatz 2G40 engine, the main bearing is a critical wear component — it maintains oil film pressure between the crankshaft journal and the engine case, which is essential for protecting internal engine components. When a main bearing wears or fails, the crankshaft develops excessive play, oil pressure drops, and the engine will begin to knock — left unaddressed, this leads to catastrophic engine failure. Replacing the bearing at the first sign of wear is the most cost-effective way to protect the engine investment in your roller.
