The Bomag 92001083 Orifice is a genuine OEM component designed for a wide range of Bomag BW-series tandem rollers and pneumatic tyred rollers, including the BW 161 AD-4, BW 202 AD-4, BW 203 AD-4, BW 190 AD-4, BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 205 AD 4, BW 24 RH, BW 25 RH, and BW 27 RH, among others. Sourced directly from Bomag, this part carries the same specifications as the original, ensuring it seats and functions exactly as intended in the hydraulic circuit. When your roller's orifice wears or becomes restricted, swapping in part number 92001083 restores proper hydraulic flow balance and keeps your compaction equipment performing at spec.
Key Features
- Genuine OEM Hydraulic Precision — manufactured to Bomag's exact flow-restriction specification, maintaining calibrated fluid metering that an off-spec substitute cannot replicate
- Direct Drop-In Replacement — machined to match the original orifice geometry and thread form, so this part installs directly into the existing hydraulic circuit without rework
- Broad BW-Series Coverage — fits Bomag tandem rollers including the BW 141 AD-4, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, BW 190 AD-4, BW 202 AD-4, BW 203 AD-4, and BW 205 AD 4, as well as BW 24 RH, BW 25 RH, and BW 27 RH pneumatic tyred rollers and the BW177PDH 5 single drum roller
- Restored Flow Control — a correctly functioning orifice meters hydraulic fluid at the designed rate, supporting consistent drum vibration, steering response, and system pressure; a clogged or eroded orifice causes sluggish or erratic machine behavior
- Fuel System and Hydraulic Safety Integrity — precise orifice sizing prevents pressure spikes that can stress downstream seals, hoses, and valves, protecting the broader hydraulic system from secondary damage
An orifice is a precision-machined restrictor fitted into a hydraulic circuit to control the flow rate of fluid between components. By limiting how quickly fluid can pass through, it regulates pressure differentials and ensures that actuators — such as vibration motors, steering cylinders, and drive circuits — receive fluid at the correct rate for smooth, controlled operation. When an orifice becomes worn, eroded, or blocked with contamination, flow rates shift outside their designed range, leading to symptoms such as inconsistent drum vibration, reduced compaction output, or unpredictable hydraulic response — making timely replacement essential to keeping the roller operating as intended.
