Bomag 05905902 Milling Transmission

The Bomag 05905902 Milling Transmission is a genuine OEM component designed for Bomag BM 1000/35, BM 1200/35, BM 1300/35, BM 1200/35 T4f, BM 1300/35 T4f, BM 1000/35-2, BM1200/35-2, and BM1000/35-2 cold milling machines. Sourced directly from Bomag, this milling transmission meets the exact engineering standards of the original unit it replaces. Correct drivetrain performance in a cold milling machine depends on a properly functioning transmission, and this genuine OEM part ensures that the milling drum receives precisely controlled power from the engine. If you are servicing any of the covered BM-series cold milling machines, part number 05905902 is the correct OEM replacement.

Key Features

• Genuine OEM Drivetrain Precision — built to the exact torque capacity and gear ratio specifications of the original Bomag milling transmission, with no compromise in power transfer characteristics
• Direct-Fit Replacement — engineered to match the original mounting interfaces and hydraulic connections of the BM-series cold milling machine drivetrain for a straightforward service installation
• Broad BM-Series Coverage — fits the BM 1000/35, BM 1200/35, BM 1300/35, BM 1200/35 T4f, BM 1300/35 T4f, BM 1000/35-2, BM1200/35-2, and BM1000/35-2 cold milling machines
• Consistent Milling Drum Output — a sound transmission maintains steady drum speed and cutting force, preserving milling depth accuracy and surface finish quality on asphalt and concrete
• Long-Term Drivetrain Protection — using a genuine Bomag transmission assembly prevents the accelerated wear to adjacent drivetrain components that an incorrectly specified unit can cause

The milling transmission is the primary power-transfer assembly between the machine's engine and the rotating milling drum. It converts and regulates engine output into the controlled rotational force needed to drive the drum's cutting tools through asphalt or concrete at consistent speed. When this transmission wears or fails, the machine loses the ability to maintain stable drum speed, resulting in uneven milling depth, excessive vibration, and potential damage to the drum drive system — all of which affect finished surface quality and machine reliability on the job.
