The Bomag 92022834 RPM Sending Unit is a genuine OEM component designed for BW 141 AD-4 and BW 151 AD-4 series tandem rollers, including the BW 141 AD-4 AM, BW 151 AD-4 AM, and BW 151 AC-4 variants. Sourced directly from Bomag, this sending unit matches the original equipment specification exactly, so installation is straightforward with no guesswork on compatibility. If your tandem roller is showing erratic engine speed readings or the RPM gauge has gone dark, this is the direct replacement to restore accurate instrumentation. DHS Equipment stocks genuine Bomag parts — order part number 92022834 with confidence.
Key Features
- Genuine OEM Signal Accuracy — engineered to deliver the correct frequency output for your Bomag roller's engine management and instrument cluster, ensuring the RPM reading reflects true engine speed
- Direct-Fit Replacement — matches the original mounting configuration and electrical connector on BW 141 AD-4 and BW 151 AD-4 tandem rollers for a clean, tool-minimal swap
- Broad Tandem Roller Coverage — fits the BW 141 AD-4, BW 141 AD-4 AM, BW 151 AD-4, BW 151 AD-4 AM, and BW 151 AC-4, covering multiple variants in the Bomag tandem roller lineup
- Protects Engine and Compaction Performance — accurate RPM data allows operators and onboard systems to maintain optimal drum frequency and engine load; a failed sending unit can mask over-revving or underperformance on the mat
- Electrical Safety Assurance — as a genuine OEM sensor, this unit meets Bomag's original resistance and signal specifications, preventing false readings that could interfere with engine protection or emissions control systems
The RPM sending unit is a magnetic or Hall-effect sensor that monitors crankshaft or flywheel rotation speed and sends a continuous electrical signal to the engine control unit and instrument panel. This signal tells the operator and the machine's control systems exactly how fast the engine is turning at any moment. When the sending unit wears out or fails, the result is typically a dead or erratic tachometer, loss of engine speed data for onboard diagnostics, and in some cases improper drum vibration frequency — all of which directly affect compaction quality and safe operation of the roller.
