The Bomag 05813174 Gear Pump is a genuine OEM replacement designed for Bomag BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 120 AD-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers. Sourced directly from Bomag, this gear pump meets the same engineering standards as the original component installed at the factory. It drops in place of the worn unit with no guesswork on fitment, keeping your roller's hydraulic system operating as intended. If your machine is showing signs of low hydraulic pressure, sluggish drum drive response, or fluid loss, replacing this pump is a critical first step.
Key Features
- Genuine OEM Hydraulic Precision — Built to exact displacement and pressure tolerances specified for Bomag tandem roller hydraulic circuits, ensuring consistent flow output from the first startup.
- Direct Replacement Fit — Matches the original port configuration and mounting dimensions for the BW 100, BW 120, and BW 125 tandem roller families, connecting directly to existing hydraulic lines and housings.
- Broad Tandem Roller Coverage — Confirmed fitment across BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, and BW 125 AC-4 tandem rollers.
- Restored Hydraulic System Performance — A properly functioning gear pump maintains the steady hydraulic pressure that powers drum vibration and propulsion; a worn pump causes erratic compaction output and reduced drive response.
- Verified Bomag Part Number — Carries part number 05813174 for straightforward cross-referencing against your machine's service manual or parts catalog.
The gear pump is the heart of a tandem roller's hydraulic system, converting mechanical energy from the engine into pressurized fluid flow that drives the drum motors, vibration system, and steering functions. When the pump wears internally — through scored gear faces or failing seals — hydraulic pressure drops, causing sluggish drum response, weak or absent vibration, and in severe cases complete loss of propulsion. Replacing a failing pump with a genuine Bomag 05813174 unit restores full system pressure and flow, returning the machine to its rated compaction performance.
