The Bomag 84030220 Central Block is a genuine OEM component designed for Bomag BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2 tandem rollers. Sourced directly from Bomag, this central block delivers an exact OEM match, ensuring the hydraulic or fluid routing circuit it serves operates exactly as engineered. If your tandem roller is showing signs of pressure loss, irregular flow, or fluid bypass, inspecting and replacing this block with a genuine part is the right first step.
Key Features
- Genuine OEM Integrity — Manufactured to Bomag's original design tolerances, ensuring correct port sizing, sealing surfaces, and flow paths for the hydraulic circuit it controls.
- Direct-Fit Replacement — Engineered to swap in without modification, matching the original mounting configuration and connection points on compatible tandem rollers.
- Broad Tandem Roller Coverage — Fits the BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 154 AD-2, and BW141AD 2, covering a key range of Bomag tandem compaction equipment.
- Hydraulic System Reliability — A correctly functioning central block maintains consistent fluid distribution across the roller's drive and vibration circuits, keeping compaction output steady and predictable.
- Verified Part Number — Order with confidence using part number 84030220, the exact Bomag catalog reference for this component.
The central block serves as a distribution hub within the machine's hydraulic system, directing pressurized fluid to the appropriate circuits — whether for drum drive, vibration, or steering functions. When this block is worn, cracked, or internally bypassing, the roller can experience loss of drive power, inconsistent vibration amplitude, or erratic steering response. Replacing a failed central block with a genuine Bomag part restores proper hydraulic routing and brings the machine back to its designed compaction performance.
