The Bomag 59070779 Ring Gear is a genuine OEM component designed for Bomag MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, and RS 650 recycler/stabilizer machines. Sourced directly from Bomag, this ring gear is manufactured to the same specifications as the original, ensuring an exact match to your machine's drivetrain assembly. If your recycler/stabilizer is showing signs of gear wear, slippage, or drive inefficiency, replacing this component with the correct OEM part restores proper mechanical engagement and power transfer. Confirm part number 59070779 against your machine's documentation before ordering to ensure compatibility.
Key Features
- Genuine OEM Tooth Geometry — machined to Bomag's original tooth profile and hardness spec, delivering the correct mesh engagement and load-bearing capacity expected of this drivetrain component
- Direct Drivetrain Replacement — this ring gear seats and indexes to the existing drive assembly on compatible machines without modification to mounting surfaces or mating components
- Broad Recycler/Stabilizer Coverage — confirmed fitment across the MPH 125, MPH 600, MPH 600 3B/4i-PB, MPH 600 EU-FLEX, and RS 650 recycler/stabilizer models
- Restored Power Transfer — a worn or damaged ring gear causes inconsistent rotor engagement and drive loss; replacing it with this OEM component brings mechanical output back to full operational spec
- Verified Part Number Integrity — ordering by Bomag part number 59070779 eliminates the guesswork of cross-referencing aftermarket catalogs and ensures you receive the correct gear for your application
The ring gear is a critical component in the rotary drive system of a recycler/stabilizer, transferring engine torque to the rotor or drive shaft through precise gear-tooth engagement. On machines like the MPH and RS series, which subject drivetrain components to high cyclic loads during soil mixing and stabilization passes, the ring gear must maintain tight tolerances to prevent backlash, heat buildup, and premature wear on mating components. When a ring gear wears or chips, operators typically experience vibration, inconsistent rotor speed, or complete drive failure — all of which halt productive compaction and stabilization work until the component is replaced.
