Overview
The ZF 4642.351.035 SPUR GEAR is a precision-machined component engineered specifically for the WG 150 series transmission. This gear sits within the intermediate shaft assembly, where it transfers rotational force from the input shaft to the output shaft, ensuring smooth power delivery under heavy loads. As an OEM genuine part, the SKU 4642.351.035 guarantees exact fitment and material integrity, matching ZF’s original tolerances to prevent premature wear. When installed alongside the 4642101109: TRANSMISSION HOUSING and the 4642301205: TRANSMISSION HOUSING, this spur gear forms the core of the gear train, enabling reliable torque transmission in demanding industrial applications.
Symptoms of Failure
When the 4642.351.035 spur gear deteriorates, operators often notice distinct failure indicators. Whining or grinding noises during gear engagement are common, especially under load, as worn teeth lose their profile. Intermittent gear slipping or loss of power transfer occurs when the gear’s flank surfaces become pitted or chipped, reducing contact area. Metallic debris in the transmission oil signals advanced wear, often accompanied by vibration through the driveline at specific RPM ranges. These symptoms typically worsen over time, making early replacement critical to avoid damage to the 0730365125: TYPE PLATE and other internal components.

Compatibility
This spur gear is primarily designed for the ZF WG 150 series, but it also fits select variants within the WG 180 and WG 200 families due to shared gear train architecture. Specifically, it is compatible with WG 150, WG 151, WG 180, and WG 200 transmissions manufactured after 2005. For proper installation, ensure the 0631311009: GROOVED STUD is torqued to specification, as this stud secures the gear to its shaft. Always verify your transmission’s serial number against ZF’s parts catalog before ordering.
