The Bomag 05742777 Temperature Sensor is a genuine OEM component designed for a wide range of Bomag tandem rollers and single drum rollers, including the BW 174 AP-4i, BW 161 AD-5, BW 190 AD-5, BW 120 AD-5, BW 100 AD-5, BW 202 AD-5, BW 138 AD-5, BW 135 AD-5, BW 124 DH-5, and BW 124 PDH-5, among others. Sourced directly from Bomag, this sensor carries the same part number 05742777 used in BOMAG's own service and parts documentation, so you can order with confidence that it matches your machine's original specification. This temperature sensor installs as a direct replacement, restoring accurate thermal monitoring to your roller's engine or hydraulic system without the need for adaptation. Whether you're servicing a BW 161 AC-5, a BW 190 ADO-5, or any other compatible model in the lineup, this genuine OEM part keeps your compaction equipment running as designed.
Key Features
- Genuine OEM Sensor Accuracy — manufactured to the exact resistance and output tolerances specified by Bomag, ensuring the machine's control system receives an accurate thermal signal at all times.
- Direct-Fit Replacement — matches the original connector, thread pitch, and mounting configuration so this sensor swaps into place without rework or custom fitting.
- Broad Tandem and Single Drum Roller Coverage — confirmed fitment across Bomag tandem rollers including the BW 174, BW 161, BW 190, BW 120, BW 100, BW 202, BW 138, and BW 135 series, as well as BW 124 DH-5 and BW 124 PDH-5 single drum rollers.
- Protects Engine and Hydraulic System Health — a correctly functioning temperature sensor enables the machine to respond to overheating conditions before damage occurs; a failed sensor can mask critical temperature spikes and lead to costly component failure.
- Safety-Critical Thermal Monitoring — accurate temperature data is essential for the machine's overtemperature warning and shutdown systems, making this sensor a key part of safe machine operation.
A temperature sensor monitors the thermal condition of the engine coolant, hydraulic fluid, or other critical systems and transmits a continuous signal to the machine's control unit. When temperatures climb beyond safe operating limits, that signal triggers warning indicators or automatic shutdowns that protect the engine and hydraulic components from heat damage. A worn or failed sensor can send incorrect readings — or no reading at all — leaving operators unaware of dangerous temperature rises and putting expensive drivetrain and hydraulic components at risk.
