ZF 4699.302.186 DRIVE PINION for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4699.302.186 DRIVE PINION is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational force from the input shaft to the planetary gearset, ensuring smooth torque conversion and reliable power delivery under heavy loads. The SKU 4699.302.186 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life. This drive pinion interfaces directly with the 4699101086 HOUSING and the 4699301223 HOUSING, forming a critical subassembly within the transmission’s main drive train.

Symptoms of Failure

• Whining or grinding noise during acceleration: Worn gear teeth on the drive pinion produce a distinct metallic sound, especially when shifting between forward and reverse gears.
• Delayed engagement or gear slipping: As the pinion loses its tooth profile, torque transfer becomes erratic, causing the transmission to hesitate before engaging or to slip under load.
• Metal particles in transmission fluid: Flaking or pitting of the pinion surface introduces ferrous debris into the oil, which can be detected during routine fluid changes or filter inspections.
• Vibration through the driveline: A damaged pinion creates rotational imbalance, transmitting noticeable vibration to the vehicle chassis at highway speeds.

Technical Specifications

Compatibility

This drive pinion is specifically designed for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in conjunction with the correct 0636302022 SCREW PLUG and 0501319149 SCREW PLUG for housing sealing. Always verify your transmission’s serial number before ordering. The pinion works with both standard and heavy-duty torque converter configurations found in these ZF platforms.
