The Bomag 05813304 Gear Pump is a genuine OEM component designed for Bomag BW 161 AD-50, BW 161 ADO-50, BW 161 AC-50, BW 191 AD-5, BW 191 ADO-5, BW 202 AD-50, BW 202 ADO-50, BW 206 AD-5, BW 206 AD-50, and BW 206 ADO-5 tandem rollers. Sourced directly from Bomag, this gear pump matches the original component in form, fit, and hydraulic specification — no guesswork, no adaptation required. Whether you are servicing a single machine or managing a fleet of tandem rollers, part number 05813304 delivers the confidence of a factory-authorized replacement.
Key Features
- Genuine OEM Hydraulic Specification — manufactured to Bomag's original flow-rate and pressure tolerances, ensuring the hydraulic circuit performs exactly as designed for tandem roller operation
- Direct Drop-In Replacement — matches the original mounting ports, shaft dimensions, and rotation direction, allowing straightforward installation without reworking lines or brackets
- Broad Tandem Roller Coverage — fits BW 161, BW 191, BW 202, and BW 206 series tandem rollers across AD-5, AD-50, ADO-5, ADO-50, and AC-50 variants, covering a wide range of Bomag asphalt compaction equipment
- Sustained Hydraulic Output — a properly functioning gear pump maintains consistent flow to the drive and vibration circuits; a worn or failing pump causes sluggish drum response, loss of vibration amplitude, and uneven compaction results
- Verified Bomag Part Number — cross-reference part number 05813304 against your machine's service documentation to confirm fitment before installation
A gear pump is the primary hydraulic power source on a tandem roller, converting engine rotation into pressurized fluid flow that drives the drum propulsion, steering, and vibration systems. When the gear pump wears or fails internally, pressure drops across the hydraulic circuit — leading to reduced travel speed, weak or absent drum vibration, and inconsistent mat density on asphalt passes. Replacing this pump with a genuine Bomag unit restores the correct flow and pressure characteristics that the machine's hydraulic system was engineered around, bringing the roller back to full compaction performance.
