The Multiquip 374468020 Pinion is a genuine OEM component designed for MT Series rammers. Sourced directly from Multiquip, this pinion is built to the exact specifications of the original part, ensuring proper mesh, load transfer, and drive engagement within the rammer's gearbox. Compatible with MT Series tampers, the part is the correct replacement when the original pinion shows wear, chipping, or loss of drive. Ordering genuine OEM means no guesswork on tooth profile, material grade, or dimensional fit.
Key Features
- Genuine OEM Gear Geometry — Manufactured to Multiquip's exact tooth profile and hardness specification, maintaining proper mesh with mating gears inside the rammer drivetrain.
- Drop-In Replacement — Matches the original mounting configuration of the MT Series rammer gearbox, installing in the same position as the factory pinion with no reworking of adjacent components.
- MT Series Fitment — Confirmed for MT Series Multiquip tampers; use part number 374468020 to verify against your machine's parts diagram before ordering.
- Sustained Drive Transmission — A correctly functioning pinion delivers consistent rotational force to the rammer's impact mechanism; a worn or chipped pinion causes irregular compaction stroke, vibration anomalies, or total loss of drive.
- Durable Under High-Cycle Loads — Rammer gearboxes operate under continuous high-frequency impact loads; this OEM pinion is made from material grades rated for that demanding duty cycle.
The pinion is a small-diameter toothed gear that meshes with a larger gear or rack inside the rammer's transmission, converting engine rotation into the rapid reciprocating motion that drives the compaction foot. In a rammer, this component is under constant high-frequency stress, making material quality and dimensional accuracy critical. When a pinion wears down or loses teeth, the drive train loses the ability to transfer power cleanly, resulting in reduced compaction force or a complete loss of rammer function.
