ZF 4642.311.012 SPUR GEAR for WG150 | OEM Genuine Part

Overview

The ZF 4642.311.012 SPUR GEAR is a precision-machined component engineered specifically for the WG 150 series transmission. This gear is responsible for transferring rotational torque between parallel shafts within the gear train, ensuring smooth power delivery and consistent load distribution under high-stress industrial conditions. As an OEM genuine part, SKU 4642.311.012 is manufactured to exact ZF tolerances, guaranteeing a direct fit and long service life. This spur gear works in concert with the 4642101047 TRANSMISSION HOUSING and the 4642301207 TRANSMISSION HOUSING to maintain proper gear alignment and shaft support within the assembly.

Symptoms of Failure

When the ZF 4642.311.012 spur gear begins to wear, operators may notice distinct performance issues. Whining or grinding noises during gear engagement often indicate tooth surface degradation or pitting. Intermittent gear slipping under load is another common symptom, particularly when the transmission is under heavy torque. Metallic debris in the transmission oil filter or drain pan signals advanced wear of the gear teeth. Additionally, vibration at specific RPM ranges can occur if the gear has developed uneven wear patterns, compromising the balance of the rotating assembly.

Technical Specifications

Compatibility

This spur gear is primarily designed for the ZF WG 150 series transmission. It is also compatible with select variants of the WG 180 and WG 200 models that share the same gear train architecture. The part is often used in industrial applications such as forklifts, airport ground support equipment, and construction machinery. For proper installation, ensure the 0730365067 TYPE PLATE is referenced to confirm the exact transmission model, and use the 0631311009 GROOVED STUD for secure mounting alignment.
