The Bomag 83630181 Rear Left Adjusting Ring is a genuine OEM component designed for Bomag cold milling machines, including the BM1000/30-2, BM1000 30-2, BM1200 30-2, BM1300/30-2, BM1300 30-2, BM 1200/30, and BM 1300/30. Sourced directly from Bomag, this ring meets the exact dimensional and material standards required for proper rear axle or drum alignment on these machines. When worn or damaged, precise adjustment is lost — replacing it with part number 83630181 restores the correct geometry and keeps the milling system operating within spec.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's exact tolerances, ensuring the adjusting ring seats and indexes correctly within the rear left assembly of the cold milling machine
- Direct OEM Replacement — this ring installs in the same position and orientation as the original, with no rework or modification to the surrounding components
- Broad Cold Milling Machine Coverage — fits BM1000/30-2, BM1000 30-2, BM1200 30-2, BM1300/30-2, BM1300 30-2, BM 1200/30, and BM 1300/30 cold milling machines
- Alignment Integrity Restored — a correctly fitted adjusting ring maintains rear-end geometry, which is critical to consistent cutting depth, even drum wear, and controlled milling passes
- Operational Safety — improper rear alignment caused by a worn adjusting ring can affect machine tracking and drum control; replacing it with part number 83630181 returns the machine to its designed operating parameters
The Rear Left Adjusting Ring is a precision positioning component used in the rear of Bomag cold milling machines to set and maintain the correct lateral or angular alignment of a rotating assembly — typically the milling drum drive or rear axle. By holding this alignment under load and vibration, it ensures the milling drum tracks true and cuts at a consistent, controlled depth. When this ring wears, develops play, or is damaged, rear-end geometry shifts, which can lead to uneven cutting, accelerated drum or bearing wear, and reduced accuracy on finished surfaces.
