Overview
The ZF 4699.302.214 SPUR GEAR is a precision-machined OEM genuine component designed for the auxiliary drive train within the WG100, WG130, and WG131 transmission series. This gear directly engages with the main shaft to transfer rotational force to the PTO (Power Take-Off) system, ensuring smooth torque delivery under heavy load conditions. As a critical element in the gear cluster, the 4699.302.214 part number is engineered to ZF’s exacting tolerances for minimal backlash and maximum durability. When installed alongside the 4699101070 HOUSING and the 4699301146 HOUSING, this spur gear forms the core of the transmission’s power distribution unit.
Symptoms of Failure
- Whining or howling noise during PTO engagement: Worn gear teeth produce a distinct high-pitched sound, especially under load, indicating surface fatigue or pitting on the 4699.302.214 spur gear.
- Intermittent gear slipping under torque: When the gear’s tooth profile degrades, it fails to maintain positive engagement, causing sudden loss of drive to auxiliary equipment.
- Metal debris in transmission oil: Flaking or chipping of the spur gear introduces ferrous particles into the lubricant, often detected during routine oil changes or when inspecting the 0634801038 SEALING RING for contamination.
- Vibration through the gearshift lever: Uneven wear on the gear’s helical or straight-cut teeth creates cyclic vibration that transmits through the driveline.

Compatibility
This spur gear is specifically engineered for the ZF WG100, WG130, and WG131 mechanical transmissions. It is also compatible with the WG180 and WG200 series when used in the auxiliary drive position. The 4699.302.214 gear interfaces directly with the 4699102105 INPUT shaft assembly and is secured within the transmission case using the 0636101411 CAP SCREW and 0631302212 CYLINDRICAL PIN. For proper sealing, always pair this gear with a new 0634801038 SEALING RING and the 4699309085 HOUSING COVER to prevent lubricant loss.
