Key Features
- OEM Gear Geometry — Manufactured to original tooth profile and pitch specifications, ensuring proper mesh and load transfer within the drivetrain.
- Drop-In Drivetrain Fit — Engineered to the same dimensions as the factory pinion, seating correctly without modification to the gear housing or shaft.
- Confirmed Fitment — Compatible with T23, T26, and T33 Multiquip ride-on rollers; cross-reference part number 12912977420 before ordering.
- Sustained Drive Performance — A properly functioning pinion maintains smooth torque transfer to the drum, keeping compaction output consistent across the full working pass.
- Wear Resistance — OEM material grade supports the continuous meshing loads typical of roller operation, resisting premature tooth wear under production compaction cycles.
A pinion is a small-diameter gear that meshes with a larger ring gear or rack to transmit rotational force through a drivetrain. In a ride-on roller, the pinion plays a critical role in transferring engine or hydraulic power to the drum drive, directly affecting how the machine propels itself and compacts the surface. When a pinion wears down or loses tooth integrity, the result is slipping, rough engagement, or a complete loss of drive — any of which takes the machine out of service until the gear is replaced.
