The Multiquip 01227411 is a genuine OEM Cylinder Block 2G40 designed for the RW1404, RW1404MR, and RW1504HF series walk-behind rollers. Sourced directly from Multiquip, this cylinder block meets the exact specifications required to restore your roller's engine to proper operating condition. It is confirmed for use on RW1404MR units at S/N 326075 and up, RW1504HF units up to S/N, and all standard RW1404 and RW1404MR configurations. Ordering by part number 01227411 ensures you receive the correct block for your specific machine's serial range.
Key Features
- Genuine OEM Engine Block Integrity — Cast and machined to the same tolerances as the original, ensuring proper bore geometry, deck surface flatness, and bearing journal alignment critical to engine longevity.
- Direct Engine Replacement — Designed to accept the same mounts, gaskets, and internal components as the original 2G40 engine block, allowing straightforward installation without sourcing additional adapter hardware.
- Serial-Range Verified Fitment — Confirmed compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) — always verify your machine's serial number before ordering.
- Engine Compression and Power Delivery — A structurally sound cylinder block maintains correct compression ratios, allowing the roller's engine to deliver consistent drum vibration force and drive performance on compaction passes.
- Fuel System and Combustion Safety — Proper sealing surfaces on the cylinder block prevent fuel vapor and exhaust gas intrusion — critical on compact walk-behind equipment where operators work in close proximity to the engine.
The cylinder block is the core structural component of a reciprocating engine — it houses the cylinder bore, crankcase, and provides the mounting points for the cylinder head, crankshaft, and accessory components. On RAMMAX walk-behind rollers like the RW1404 and RW1504HF series, a compromised cylinder block — whether cracked, warped, or damaged at sealing surfaces — results in loss of compression, oil contamination, and ultimately engine failure. Replacing the block with a genuine OEM unit restores the correct internal geometry and sealing integrity needed to return the machine to full compaction performance.
