Bomag Arm,Wiper | Part 32121246

The Bomag 32121246 Wiper Arm is a genuine OEM replacement designed for a wide range of Bomag single drum rollers, refuse and landfill compactors, and soil compactors, including the BW 213 D-4, BW 226 DH-4, BW 177 DH-4, BC 472 RB, BC 462 EB, and many more machines in the BW and BC families. Sourced directly from Bomag, this wiper arm matches the original component exactly — same attachment geometry, same sweep arc, and the same mounting interface as the part it replaces. This genuine OEM component delivers the fit and function your machine was built around, keeping the operator cab view clear in rain or dusty jobsite washdowns. Confirm your model against the fitment list to ensure part number 32121246 is the correct match for your machine.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original specifications, with the correct arm length, pivot geometry, and blade retention clip that aftermarket versions frequently get wrong on heavy compaction equipment
• Direct-Mount Replacement — bolts to the existing wiper motor spline shaft using the original hardware, with no re-drilling or bracket modification needed to complete the swap
• Broad BW and BC Series Coverage — fits BW-series single drum rollers including the BW 177, BW 213, BW 214, BW 216, BW 219, and BW 226 families, plus BC 472 RB refuse compactors, BC 472 RS refuse compactors, and BC 462 EB soil compactors and BC 462 RB refuse compactors
• Full Cab Visibility Restored — a properly tensioned wiper arm holds the blade firmly against the glass throughout the wipe cycle; a worn or bent arm causes streaking and skipping that impairs the operator's view of grade, edge, and surrounding personnel
• Operator Visibility Safety — clear windshield sight lines are a fundamental cab safety requirement on ride-on compaction equipment; replacing a fatigued wiper arm restores the wiping pressure needed to meet that standard

The wiper arm is the mechanical link between the wiper motor's output shaft and the blade assembly. It translates the motor's oscillating motion into a sweeping arc across the windshield, while its internal spring tension keeps the blade pressed against the glass under wind load and vibration. On heavy compaction equipment like single drum rollers and landfill compactors, constant machine vibration accelerates fatigue in the arm's pivot and spring, eventually causing the blade to lift off the glass or chatter across it. A failed wiper arm leaves the operator without adequate visibility in wet or dusty conditions — a situation that compromises both productivity and safety on the compaction pass.
