ZF 4642.107.004 SPEEDOMETER for WG150 | OEM Genuine Part

Overview

The ZF 4642.107.004 SPEEDOMETER is a precision-engineered OEM component specifically designed for the WG 150 Series transmission. This critical sensor monitors output shaft rotational speed and relays real-time data to the vehicle’s electronic control unit (ECU) or dashboard gauge. Positioned directly within the transmission housing, it ensures accurate speed readings for optimal gear shift timing and fuel efficiency. The SKU 4642.107.004 is manufactured to ZF’s exacting standards, guaranteeing a direct fit and long service life in heavy-duty industrial applications. When paired with a robust TRANSMISSION HOUSING (4642101047), this speedometer maintains precise communication between the drivetrain and operator controls.

Symptoms of Failure

• Erratic or fluctuating speed readings: A failing 4642.107.004 often causes the speedometer needle to jump or drop unexpectedly, leading to incorrect shift points and reduced transmission efficiency.
• Complete loss of speed signal: When the sensor wears out, the ECU may register zero speed, triggering a limp-home mode or preventing the transmission from shifting out of neutral.
• Oil seepage around the sensor mount: Degraded seals on this OEM part can allow transmission fluid to leak past the housing, potentially contaminating electrical connectors and causing intermittent faults.
• Harsh or delayed gear engagement: Without accurate speed data from the 4642.107.004, the transmission control module may apply incorrect clutch pressures, resulting in jarring shifts or slipping under load.

Technical Specifications

Compatibility

This genuine ZF speedometer is primarily engineered for the WG 150 Series, but it also fits select models in the WG 180 and WG 200 families due to shared mounting interfaces. It is commonly used in ZF 6WG150, 6WG180, and 6WG200 transmissions found in construction loaders, mining trucks, and agricultural tractors. For proper installation, ensure the mating surface on your TRANSMISSION HOUSING (4642301207) is clean and free of debris. Always verify the TYPE PLATE (0730365067) on your transmission to confirm the exact series before ordering. The sensor is secured using a GROOVED STUD (0631311009), which must be torqued to factory specifications to prevent vibration-induced loosening.
