The Bomag 05901790 Sun Gear Shaft is a genuine OEM component designed for Bomag MPH 122, MPH 125, MPH 600, and RS 650 recycler/stabilizers. Sourced directly from Bomag, this shaft delivers an exact-match replacement that slots into the planetary drive assembly without adaptation. Confirmed fitment spans the full MPH and RS 650 recycler/stabilizer range covered by part number 05901790, giving operators confidence they are installing the correct component from the first attempt.
Key Features
- Genuine OEM Planetary Precision — machined to Bomag's exact gear geometry and material specifications, ensuring correct torque transmission through the planetary drive assembly without premature wear
- Direct Drop-In Replacement — engineered to match the original shaft's dimensions, spline count, and interface points for a straightforward installation in the planetary gearbox
- Broad Recycler / Stabilizer Coverage — fits Bomag MPH 122, MPH 122-2, MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, and RS 650 recycler/stabilizers
- Sustained Drive Efficiency — a correctly functioning sun gear shaft distributes rotational load evenly across the planet gears; a worn or damaged shaft causes uneven gear loading, power loss, and eventual drivetrain failure
- Verified Part Number Integrity — order by Bomag part number 05901790 for full confidence that the correct shaft is matched to your machine's planetary system
The sun gear shaft sits at the center of a planetary gear set and serves as the primary input driver, transferring rotational force from the drive motor outward to the surrounding planet gears. In heavy-duty recycler and stabilizer applications, this shaft is subject to high continuous torque loads — wear, spline damage, or fracture will cause the planetary assembly to lose efficiency or fail to transfer power altogether, taking the machine's rotor drive offline. Replacing this shaft with a genuine Bomag part restores the correct power path and protects the surrounding planetary components from secondary damage caused by a degraded shaft.
