Overview
The ZF 4616.107.002 SPEEDOMETER is a critical electromechanical component designed specifically for the WG 65 Series transmission. This OEM genuine part monitors output shaft rotation and relays precise speed data to the vehicle’s instrumentation system. Positioned directly on the transmission housing, it interfaces with the drivetrain to ensure accurate velocity readings for both operator display and electronic control modules. The SKU 4616.107.002 is engineered to ZF’s exacting tolerances, providing reliable signal transmission under high-torque and heavy-load conditions common in industrial applications. When paired with a properly sealed 4616105413: OUTPUT assembly, this speedometer maintains consistent performance throughout the transmission’s service life.
Symptoms of Failure
When the ZF 4616.107.002 speedometer begins to fail, operators may notice erratic or fluctuating speed readings on the dashboard display, often accompanied by intermittent signal loss during gear shifts. A second common symptom is complete speedometer failure where the gauge drops to zero while the vehicle is moving, frequently caused by internal gear wear or magnetic sensor degradation. Third, transmission control module errors may appear as diagnostic trouble codes (DTCs) related to speed input, leading to harsh shifting or limp-home mode activation. Finally, oil contamination near the sensor housing can occur if the O-ring seal fails, allowing transmission fluid to seep past the mounting point—a sign that the 0636011038: HEXAGON SCREW securing the unit may need retorquing or replacement.

Compatibility
This ZF 4616.107.002 speedometer is primarily designed for the WG 65 Series transmission family, but its mounting pattern and signal characteristics also make it suitable for select models in the WG180 and WG200 series. It is commonly found in off-highway vehicles, construction equipment, and heavy-duty trucks equipped with ZF’s WG-series powershift transmissions. For proper installation, ensure the 4616203017: OUTPUT FLANGE is free of debris and the 4616101117: TRANSMISSION HOUSING mating surface is clean. Always verify the drive gear ratio matches your specific transmission variant to avoid calibration errors.
