Multiquip 01224400 Inlet Rocker 2G40

The Multiquip 01224400 Inlet Rocker 2G40 is a genuine OEM component designed for RAMMAX walk-behind rollers including the RW1404, RW1404MR, and RW1504HF. Sourced directly from Multiquip, this rocker arm is manufactured to the exact tolerances required by the engine's valve train, ensuring correct geometry and reliable contact with the intake valve. It is confirmed to fit RW1404MR units at S/N 326075 and up, RW1504HF units up to S/N, and all standard RW1404 configurations.

Key Features

• Genuine OEM Valve Train Precision — Manufactured to exact pivot geometry and arm-length specifications, ensuring correct valve lift and timing on the 2G40 engine.
• Direct Drop-In Installation — Matches the original rocker shaft mounting and valve stem contact point for straightforward removal and reinstallation without machining or adaptation.
• Confirmed Fitment — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX roller models.
• Protects Engine Performance — A correctly functioning inlet rocker maintains proper air-fuel charge intake; a worn or damaged rocker causes misfires, power loss, and accelerated valve seat wear.
• Long-Term Wear Resistance — Cast and finished to resist the repeated impact loading of continuous valve actuation across extended compaction cycles.

The inlet rocker arm transfers motion from the camshaft lobe — via the pushrod — to open the intake valve at precisely the right moment in the engine's combustion cycle. When functioning correctly, it ensures the cylinder receives a full, properly timed charge of air and fuel with every stroke. When a rocker arm wears, cracks, or loses its adjustment, valve lift becomes inconsistent, leading to rough running, reduced power output, excessive fuel consumption, and potential damage to the valve stem or seat over time. Replacing a worn inlet rocker with a correct OEM unit restores proper valve train geometry and engine efficiency.
