The Bomag 05901038 Reduction Gear is a genuine OEM component designed for Bomag BM 1000/30-2, BM 1200/30-2, BM 1300/30-2, BM 1200/30, and BM 1300/30 cold milling machines. Sourced directly from Bomag, this reduction gear meets the original engineering requirements for these machines, ensuring proper torque transmission and drivetrain integrity. Confirmed fitment across the BM 1000 and BM 1300 cold milling series makes part number 05901038 the straightforward, dependable choice when this component requires replacement.
Key Features
- Genuine OEM Gear Tolerancing — manufactured to Bomag's original specifications, delivering the correct gear ratio, tooth profile, and load rating required for cold milling drivetrain performance
- Direct-Fit Replacement — engineered to match the original mounting configuration and shaft interfaces on BM-series cold milling machines, installing in place of the worn component without adaptation
- Broad BM-Series Coverage — fits BM 1000/30-2, BM 1200/30-2, BM 1300/30-2, BM 1200/30, and BM 1300/30 cold milling machines
- Sustained Cutting Drum Output — a correctly functioning reduction gear maintains consistent rotor speed and torque delivery to the cutting drum; a worn or damaged unit causes loss of milling force, irregular drum speed, and accelerated drivetrain wear
- Drivetrain Protection — proper gear mesh and backlash at OEM spec reduces stress on adjacent drivetrain components, helping preserve the service life of connected shafts and bearings
A reduction gear steps down input speed from the engine or hydraulic motor to the lower output speed required by the milling drum drive, while multiplying torque to deliver the cutting force these machines demand. In cold milling machines, this component must handle high continuous loads and resist the shock loads generated during aggressive asphalt and concrete cutting. When the reduction gear wears, develops excessive backlash, or fails, the cutting drum loses consistent rotational speed and torque, resulting in uneven milling depth, increased stress on the surrounding drivetrain, and potential machine shutdown.
