The Multiquip 01222100 Gear Wheel with Governor W is a genuine OEM component designed for RW1404, RW1404MR, and RW1504HF series RAMMAX walk-behind rollers. Sourced directly from Multiquip, this part meets the exact specifications of the original component it replaces, ensuring proper fit and function within the engine's governor system. Confirmed fitment includes the RW1404MR (S/N 326075 and up) and RW1504HF (up to S/N ), as well as the standard RW1404 — verify your serial number before ordering to confirm compatibility with your unit.
Key Features
- Genuine OEM Gear Tolerancing — Machined to the exact tooth profile and dimensional spec of the original, ensuring proper mesh with mating governor components and consistent rotational transfer.
- Direct-Fit Installation — Designed to seat and align exactly as the factory component did, with no reworking of mounting points or governor linkage required.
- Confirmed Fitment for RAMMAX Roller Models — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188); always cross-reference your serial number before ordering.
- Governor System Integrity — A worn or damaged gear wheel disrupts engine speed regulation, causing erratic RPM behavior that affects compaction consistency and drum speed control.
- Authorized Multiquip Part — Carrying Multiquip part number 01222100, this is a factory-authorized replacement backed by Multiquip's OEM supply chain.
The gear wheel with governor is a critical component within the engine's mechanical governor assembly. It transmits rotational motion to the governor mechanism, which regulates engine speed under varying load conditions — keeping drum output consistent across different compaction passes. When this gear wears, chips, or loses tooth integrity, the governor loses its ability to accurately sense and respond to engine speed changes, resulting in unstable throttle behavior, inconsistent drum vibration, and potential engine over-revving that can cause further drivetrain damage.
