The Bomag 05813176 Gear Pump is a genuine OEM component designed for BW 161 AD-4 and BW 161 AC-4 tandem rollers. Sourced directly from Bomag, this gear pump meets the original engineering specifications for your machine's hydraulic system. It is a direct replacement for worn or failed units on BW 161 series tandem rollers, ensuring correct hydraulic flow and pressure output are fully restored.
Key Features
- Genuine OEM Hydraulic Precision — Built to Bomag's original displacement and pressure tolerances, this gear pump delivers the exact hydraulic output your BW 161 tandem roller's system requires.
- Direct Drop-In Replacement — Engineered to match the original mounting configuration and port sizing, this part installs without modification to existing hydraulic lines or brackets.
- Confirmed Fitment — Compatible with BW 161 AD-4 and BW 161 AC-4 tandem rollers; cross-reference part number 05813176 before ordering to confirm your machine's configuration.
- Restored Hydraulic Flow — A worn gear pump causes sluggish drum drive, erratic vibration control, and loss of steering response; replacing it with this OEM unit brings hydraulic performance back to spec.
- Long-Term System Protection — Correct internal clearances prevent pressure bypass and reduce heat buildup, protecting downstream hydraulic components from premature wear.
A gear pump is the heart of a tandem roller's hydraulic circuit, converting engine power into pressurized fluid flow that drives the drum motors, vibration system, and steering. When the pump wears internally, internal leakage increases, pressure drops, and the machine loses the consistent force needed to compact asphalt evenly. Replacing a failing pump promptly prevents cascading damage to valves, motors, and cylinders throughout the hydraulic system.
