The Bomag 05903876 Reduction Gear is a genuine OEM component designed for Bomag BM 1000/35, BM 1200/35, and BM 1300/35 cold milling machines. Sourced directly from Bomag, this reduction gear meets the same specifications as the original part installed at the factory, ensuring an exact match for your machine. Confirmed fitment covers the full range of compatible Bomag cold milling machines, including Tier 4f variants and second-generation models such as the BM 1000/35-2, BM 1200/35-2, and BM 1300/35 T4f.
Key Features
- Genuine OEM Gear Tolerancing — manufactured to Bomag's own specifications, delivering the correct gear ratio, load capacity, and mesh tolerancing required for cold milling drivetrain performance
- Direct OEM Replacement — matches the original mounting configuration and interface dimensions, allowing this gear to drop into place without modification
- Broad Cold Milling Machine Coverage — fits Bomag BM 1000/35, BM 1000/35-2, BM 1200/35, BM 1200/35-2, BM 1200/35 T4f, BM 1300/35, and BM 1300/35 T4f cold milling machines
- Sustained Drivetrain Output — a properly functioning reduction gear maintains the correct torque multiplication to the milling drum, keeping cutting performance consistent across varying surface conditions
- Verified Part Number — order with confidence using Bomag part number 05903876 to confirm you are receiving the correct unit for your machine
A reduction gear is a mechanical assembly that steps down rotational speed from a power source while multiplying output torque. In a cold milling machine, the reduction gear transfers and regulates power from the drive system to the milling drum, ensuring the drum turns at the correct speed and with sufficient force to cut asphalt or concrete effectively. When the reduction gear wears or fails, it can result in lost cutting power, irregular drum speed, excessive heat buildup in the drivetrain, or complete loss of drum drive — any of which will halt milling operations and may cause further damage to surrounding drivetrain components.
