The Bomag 05901614 Sun Gear Shaft is a genuine OEM component designed for BC-series refuse/landfill compactors and soil compactors, including the BC 671 RB, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RS, BC 672 RB, BC 772 RB-2, BC 672 RB-2, BC 772 RS-2, BC 772 EB-2, BC 672 EB-2, BC 772 RB-3, BC 672 RB-3, BC 772 RS-3, BC 772 RB-4, BC 772 RS-4, BC 672 RB-4, and BC 772 EB-4. Sourced directly from Bomag, this sun gear shaft meets the same manufacturing standards as the original drivetrain component it replaces. Ordering by part number 05901614 ensures you receive the correct shaft geometry and spline specification for a direct installation into the planetary drive system of your BC-series machine.
Key Features
- Genuine OEM Drivetrain Precision — manufactured to Bomag's exact spline profile and shaft tolerances, ensuring proper load transfer through the planetary gear set without slippage or premature wear
- Direct Installation Fit — this sun gear shaft matches the original mounting configuration and spline count of the BC-series planetary drive, dropping straight into the carrier assembly without rework
- Broad BC-Series Coverage — fits BC 671 RB, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RS, BC 672 RB, BC 772 RB-2, BC 672 RB-2, BC 772 RS-2, BC 772 RB-3, BC 672 RB-3, BC 772 RS-3, BC 772 RB-4, BC 772 RS-4, BC 672 RB-4 refuse/landfill compactors, plus BC 772 EB-2 and BC 772 EB-4 soil compactors
- Sustained Drive Torque — a correctly functioning sun gear shaft maintains consistent torque distribution across the wheel-end planetary gear set, allowing the compactor to deliver full tractive effort on landfill and soil surfaces
- Verified by Part Number 05901614 — cross-reference this number against your Bomag parts manual to confirm application before ordering, eliminating the risk of fitting an incompatible shaft
The sun gear shaft is the central input element of a planetary wheel-end or final-drive gear set. It meshes with the surrounding planet gears and transmits engine torque outward through the gear reduction stage, ultimately driving the wheel or drum. When the sun gear shaft wears, develops spline damage, or fractures, the planetary assembly loses the ability to transfer power efficiently — resulting in reduced traction, uneven drive force across axles, or complete loss of wheel-end power on the affected side. Replacing this component promptly with a genuine Bomag part restores full drivetrain integrity and protects the surrounding planet gears and ring gear from secondary damage.
