The Wacker Neuson Drive Pinion Gear is a genuine OEM component designed for the GPS5600A and GPS6600A portable generator series, the GS4.6A and GS5.7A 50Hz generator family, and WB16 series Power Buggies. As a direct factory replacement, this gear restores proper power transfer within the drivetrain to original specifications. It is also confirmed to fit the RSS800A Single Drum Walk-Behind Roller, making it a widely shared drivetrain component across several Wacker Neuson product lines.
Key Features
- Genuine OEM Gear Geometry — Manufactured to exact tooth profile and hardness specifications, ensuring correct mesh engagement and load transfer without wear-accelerating mismatches.
- Drop-In Drivetrain Replacement — Engineered to the original shaft interface and bearing seat dimensions, allowing straightforward installation with no machining or fitment adjustment.
- Broad Model Coverage — Fits GPS5600A, GPS6600A, GS4.6A, GS4.6AE, GS5.5A, GS5.7A, GS5.7AE, GS5.6A generators, WB16 series Power Buggies, and the RSS800A roller.
- Sustained Power Transmission — A correctly functioning drive pinion gear maintains consistent rotational output; a worn or chipped gear causes vibration, noise, and eventual drivetrain seizure that can take a machine out of service entirely.
- Sourced Directly from Wacker Neuson — Carries the full backing of the Wacker Neuson OEM parts program, so the part number, material grade, and dimensional tolerances are traceable to the original design.
The drive pinion gear is a core element of the power transmission assembly, transferring rotational force from the engine or motor to the driven output shaft. It works in constant mesh with a mating gear, and the precision of its tooth geometry directly determines how efficiently and smoothly that power is delivered. When a pinion gear wears, chips, or loses its surface hardness, it introduces backlash and noise into the drivetrain, and left unaddressed, the damage propagates to the mating gear and bearings. Replacing a worn drive pinion gear promptly with a correctly spec'd OEM part restores clean power transfer and protects the surrounding drivetrain components from secondary damage.
