The Bomag 05901570 Sun Gear is a genuine OEM component designed for BC-series refuse/landfill compactors, BC-series soil compactors, and the BW 332 single drum roller. Sourced directly from Bomag, this sun gear meets the exact tolerances and material specifications of the original part — giving you a direct, like-for-like replacement. Confirmed fitment spans a wide range of BC-family machines, 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, as well as the BW 332 single drum roller.
Key Features
- Precision-Cut OEM Gear Teeth — manufactured to Bomag's original tooth profile and hardness specifications, ensuring correct torque transmission within the planetary gear set
- Drop-In Replacement — matches the original sun gear's dimensions and spline interface exactly, allowing direct installation without machining or adaptation
- Broad Fitment Coverage — compatible with BC 671 RB, BC 771 RB, BC 772 RB, BC 672 RB, BC 772 EB-2, BC 672 EB-2, BC 772 RB-4, BC 772 EB-4, BW 332, and additional BC-series models across refuse/landfill compactor, soil compactor, and single drum roller applications
- Restored Drive Efficiency — a correctly functioning sun gear maintains proper power distribution through the planetary system; a worn or damaged one causes slippage, uneven torque output, and accelerated wear on surrounding gear components
- Genuine Bomag Part — supplied under Bomag's OEM part number 05901570, so you can order with confidence that the gear you receive is the exact component specified for your machine
The sun gear is the central driving element of a planetary gear assembly. It meshes with the surrounding planet gears to transfer rotational force from the input shaft outward through the gear set, multiplying torque and reducing speed to drive the machine's wheels or drum. When the sun gear wears, chips, or loses its tooth geometry, the planetary system loses efficiency — resulting in rough operation, power loss, and increased stress on the planet gears and ring gear. Replacing a failed sun gear with the correct OEM component restores full drive performance and protects the surrounding components from secondary damage.
