The Multiquip 01239901 is a genuine OEM Pinion 2G40 RW1404MR designed for RAMMAX walk-behind roller models including the RW1404, RW1404MR, and RW1504HF. As a direct OEM replacement sourced through the Multiquip parts program, this pinion is manufactured to the same specifications as the original component installed at the factory. Verified fitment applies to RW1404MR units at S/N 326075 and up, RW1504HF units up to S/N, and standard RW1404 models. Ordering by part number 01239901 ensures you receive the correct gear for your specific roller configuration.

Key Features

  • Genuine OEM Gear Geometry — Manufactured to the original tooth profile and pitch specifications, ensuring correct mesh and load transfer within the drive system.
  • Direct Drop-In Replacement — Engineered to the same dimensional tolerances as the original, allowing straightforward installation without modification to mating components.
  • Confirmed Roller Fitment — Compatible with RW1404, RW1404MR (S/N 326075 and up), and RW1504HF (up to S/N 1534188) RAMMAX walk-behind rollers.
  • Drive System Integrity — A worn or damaged pinion causes uneven power transfer, vibration, and accelerated wear on the mating gear — replacing it promptly restores smooth, consistent drum drive.
  • Verified Part Number — Cross-reference 01239901 against your serial number range before ordering to confirm the correct pinion variant for your machine.

The pinion is a small but critical gear within the roller's drive train, responsible for transmitting rotational force from the drive shaft to the larger ring or spur gear that turns the drum. When the pinion wears, chips, or loses tooth contact, the result is slippage, noise, and a loss of compaction force at the drum — directly impacting the quality and consistency of the compacted surface. Replacing a worn pinion with the correct OEM part restores the mechanical advantage and smooth engagement the drive system depends on.
