The Bomag 05971049 Tachometer Sending Unit is a genuine OEM component designed for Bomag tandem rollers including the BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 161 AC-2, BW 202 AD-2, and BW 202 AHD-2. Sourced directly from Bomag, this sending unit is an exact match for the original, ensuring correct signal output and a drop-in installation with no guesswork. If your tandem roller is showing inaccurate RPM readings or a non-responsive tachometer, this is the part that restores accurate engine speed monitoring to your machine.
Key Features
- Genuine OEM Signal Accuracy — Engineered to Bomag's exact output specifications, this sending unit delivers the precise electrical signal your tachometer gauge requires for accurate RPM readings.
- Direct OEM Replacement — Matches the original connector, thread pitch, and mounting configuration for a straightforward swap on compatible Bomag tandem rollers.
- Broad Tandem Roller Coverage — Fits the BW 141 AD-2, BW 144 AD-2, BW 151 AC-2, BW 151 AD-2, BW 161 AC-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers.
- Protects Engine Health — A functioning tachometer sending unit keeps operators informed of live engine speed, enabling proper machine operation and preventing over-revving or under-loading that can accelerate engine wear.
- Verified by Part Number 05971049 — Cross-reference part number 05971049 against your machine's parts manual before ordering to confirm fitment for your specific serial range.
The tachometer sending unit is a magnetic or electronic sensor mounted on the engine that monitors crankshaft or flywheel rotation speed and converts it into an electrical signal sent to the tachometer gauge on the operator panel. This signal gives the operator real-time engine RPM data, which is critical for running the machine at the correct speed for compaction performance and fuel efficiency. When this sending unit fails or degrades, the tachometer may read zero, fluctuate erratically, or stop responding entirely — leaving the operator without a key performance indicator and making it difficult to detect engine irregularities before they become costly problems.
