Bomag 05973004 Level Sending Unit

The Bomag 05973004 Level Sending Unit is a genuine OEM component designed for Bomag BW-series tandem rollers, including the BW 164 AD, BW 174 AD, BW 202 AD-2, and related models. Sourced directly from Bomag, this unit matches the original specification for accurate fluid level monitoring across the full range of compatible machines. It installs directly in place of the original sending unit, requiring no adaptation or reworking of existing connections. Contractors running BW 161, BW 164, BW 170, BW 174, or BW 202 tandem rollers can order with confidence knowing part number 05973004 is the correct OEM-matched component.

Key Features

• OEM Sensor Accuracy — Genuine Bomag construction ensures the sending unit delivers the correct signal output and resistance range for accurate fluid level readings on your tandem roller's gauge or warning system.
• Direct-Fit Replacement — Engineered to match the original mounting thread, connector, and float geometry, so this sending unit seats and connects exactly as the factory unit did.
• Broad Tandem Roller Coverage — Compatible with a wide range of Bomag tandem rollers including the BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD, BW 164 AD-2, BW 170 AD, BW 170 AD-2 AM, BW 174 AC, BW 174 AC AM, BW 174 AC-2, BW 174 AC-2 AM, BW 174 ACP-AM, BW 174 AD, BW 174 AD AM, BW 174 AD-2, BW 174 AD-2 AM, BW 184 AD, BW 202 AD-2, and BW 202 AHD-2.
• Protects Against Undetected Low Fluid Levels — A faulty or failed sending unit leaves operators without warning when fluid drops to a critical level, risking component damage or unexpected shutdown. Replacing it with part number 05973004 restores full monitoring function.
• Fuel and Fluid System Integrity — Correct sensor operation is essential for safe machine management — an inaccurate or non-functional level reading can lead to operating a roller dry, which has direct implications for drivetrain and hydraulic health.

The level sending unit monitors fluid levels within the machine and transmits a corresponding signal to the operator's gauge or warning indicator. It typically uses a float-and-resistor mechanism that changes electrical resistance as the fluid level rises or falls, giving the operator a continuous readout or triggering a low-level alert. When the sending unit fails or corrodes, the gauge may read incorrectly — showing full when the tank is low, or triggering false warnings — leaving the operator without a reliable indication of fluid status. Replacing a worn or faulty unit restores the accuracy of the machine's level monitoring system and helps prevent the kind of fluid-related damage that results from running critical systems dry.
