Overview
The ZF 4699.302.217 DRIVE PINION is a precision-machined component engineered for the input shaft assembly of ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part transmits rotational force from the torque converter directly into the planetary gearset, ensuring smooth power delivery under heavy industrial loads. The SKU 4699.302.217 is manufactured to exacting ZF tolerances, featuring hardened alloy steel construction to withstand continuous high-torque stress. It interfaces directly with the 4699101071 HOUSING and the 4699301145 HOUSING to maintain correct gear mesh alignment. Without this drive pinion, the transmission cannot engage forward or reverse gears.
Symptoms of Failure
- Whining or grinding noise during acceleration – Worn pinion teeth create audible metal-on-metal contact, especially under load in WG100 models.
- Intermittent gear slippage in forward ranges – A damaged drive pinion loses positive engagement with the mating gear, causing sudden RPM spikes without vehicle movement.
- Metallic debris in transmission fluid – Flaking or chipped pinion teeth contaminate the oil, often visible during routine drain intervals.
- Vibration through the driveline at low speeds – Uneven wear on the pinion’s splines or bearing surface induces harmonic shaking in the 4699309085 HOUSING COVER.

Compatibility
This drive pinion is specifically engineered for ZF WG100, WG130, and WG131 series transmissions used in wheel loaders, forklifts, and agricultural tractors. It is also compatible with select variants of the WG180 and WG200 models when paired with the correct 0636101411 CAP SCREW for housing retention. Always verify your transmission’s serial number against the OEM parts catalog before installation. The pinion is not interchangeable with WG150 or WG250 series without additional adapter components.
