The Bomag 31120311 Wiper Arm is a genuine OEM component designed for BW 120 AD tandem rollers and BW 212 D-2 single drum rollers. Sourced directly from Bomag, this wiper arm matches the original fitment specifications so it mounts to the wiper linkage without modification. It is the correct replacement when the existing arm is bent, corroded, or no longer holds proper blade tension against the glass. Operators running BW 120 AD or BW 212 D-2 equipment can order with confidence knowing part number 31120311 is the exact unit Bomag specifies for these machines.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, ensuring the arm holds correct blade pressure and sweep angle across its full arc
- Direct-Mount Replacement — engineered to attach to the existing wiper pivot and linkage points on covered models, so installation is straightforward and no hardware adaptation is needed
- Confirmed Fitment — verified for BW 120 AD tandem rollers and BW 212 D-2 single drum rollers using Bomag part number 31120311
- Restored Visibility — a properly tensioned wiper arm keeps the blade seated firmly against the cab glass, maintaining a clear sightline for the operator in wet or dusty conditions
- Corrosion-Resistant Integrity — built to withstand the outdoor exposure and vibration loads typical of roller operation, resisting the flexing and surface degradation that cause OEM arms to loosen or fail over time
The wiper arm is the mechanical link between the wiper motor drive and the rubber blade — it transfers the oscillating motion of the pivot across the windshield in a controlled arc. When the arm is worn, bent, or has lost spring tension, the blade lifts away from the glass and leaves streaks or uncleared zones that obstruct the operator's view. On compact equipment like tandem and single drum rollers, where the operator is working in close proximity to other crew and tight site boundaries, unobstructed forward visibility is essential to safe machine control. Replacing a damaged wiper arm with a correctly tensioned OEM unit restores full blade contact and dependable windshield clearing.
