The Bomag 05901613 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 772 RB, BC 772 RS, BC 672 RB, BC 772 EB-2, BC 672 EB-2, and related generation variants. Sourced directly from Bomag, this sun gear shaft matches the original part in every critical dimension, ensuring a correct drop-in fit within the planetary drive system. Confirmed fitment spans the full BC 6- and BC 7-series lineup across RB, RS, and EB compactor configurations through the -4 generation.
Key Features
- Genuine OEM Planetary Drive Accuracy — manufactured to Bomag's original specifications, this sun gear shaft delivers the precise tooth geometry and material hardness required for proper planetary gear engagement in heavy-duty compactor drivetrains
- Direct Replacement Fit — installs directly into the planetary drive assembly using part number 05901613 as the verified reference, with no modification needed to housings, bearings, or adjacent gear components
- Broad BC-Series Coverage — fits BC 671 RB, BC 672 RB, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RS, BC 772 EB-2, BC 672 EB-2, and all intermediate and later generation variants through the -4 series, covering both refuse/landfill compactors and soil compactors
- Drivetrain Load Integrity — a correctly fitted sun gear shaft transmits torque evenly across the planetary set, preventing uneven gear wear, heat buildup, and premature failure of surrounding drive components under the sustained high-load cycles typical of landfill and soil compaction work
- Long-Term Drive System Protection — using the correct OEM shaft maintains proper gear mesh tolerances, protecting ring gears, planet gears, and bearings from accelerated wear caused by a worn or undersized replacement shaft
The sun gear shaft is a central component of the planetary reduction drive found in large compactor wheel motors and final drives. It sits at the core of the planetary gear set and transmits rotational input from the motor into the planet gears, which then drive the wheel hub at a reduced speed and multiplied torque. When the sun gear shaft wears, develops spline damage, or fails, torque transfer becomes uneven or lost entirely, resulting in reduced traction, abnormal drivetrain noise, and potential complete loss of drive to one or more wheels — a critical issue on a machine operating across uneven landfill terrain or compacted soil.
