The Bomag 65003184 Orifice is a genuine OEM component designed for Bomag BW 135 AD, BW 138 AC, BW 138 AD, and BW 138-AD tandem rollers. Sourced directly from Bomag, this orifice delivers the exact dimensional tolerances and flow characteristics required to maintain correct hydraulic circuit operation. If you're servicing one of these tandem rollers and need a trustworthy, spec-accurate replacement, this is the correct part for the job.
Key Features
- Genuine OEM Flow Precision — manufactured to Bomag's exact orifice bore specification, ensuring consistent, calibrated hydraulic fluid metering with no variation from the original design
- Direct-Fit Replacement — engineered to install into the hydraulic circuit of BW 135 AD, BW 138 AC, BW 138 AD, and BW 138-AD tandem rollers without modification
- Confirmed Tandem Roller Fitment — verified for the BW 135 AD, BW 138 AC, BW 138 AD, and BW 138-AD, covering multiple variants within this compact tandem roller family
- Hydraulic System Integrity — a correctly sized orifice maintains controlled flow rates across the hydraulic circuit; an undersized or oversized replacement can cause erratic pressure, overheating, or inconsistent drum drive performance
- Authentic Part Number Assurance — carries Bomag part number 65003184, making cross-referencing with service manuals and BOMAG documentation straightforward and accurate
An orifice is a precision-drilled restrictor fitted within a hydraulic circuit to control the rate and direction of fluid flow between components. By metering fluid to specific actuators or control valves, it regulates pressure differentials and ensures each part of the hydraulic system receives the correct flow volume at the correct time. When an orifice becomes worn, clogged, or is replaced with an incorrectly sized unit, the hydraulic circuit can lose its calibration — leading to uneven drum vibration, sluggish or erratic drive response, and accelerated wear on downstream hydraulic components.
