Overview
The ZF 4699.302.215 SPUR GEAR is a precision-engineered component designed for the auxiliary drive and power take-off (PTO) systems within the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational force between parallel shafts, ensuring smooth torque delivery in heavy-duty industrial applications. The spur gear (SKU: 4699.302.215) is housed within the main gear cluster and directly interfaces with the 4699101070: HOUSING to maintain proper gear alignment and load distribution. Its straight-cut tooth profile minimizes axial thrust, making it critical for consistent power flow in construction and agricultural machinery.
Symptoms of Failure
- Whining or grinding noise during PTO engagement – Worn teeth on the 4699.302.215 spur gear create a high-pitched metallic sound, often mistaken for bearing failure. This typically occurs under load in WG130 transmissions.
- Intermittent gear slipping under torque – When the spur gear’s tooth profile degrades, the transmission may lose drive momentarily, especially during gear changes in WG131 units.
- Metal particles in transmission oil – Flaking or pitting on the gear surface releases ferrous debris into the lubricant, detectable during routine oil analysis for WG100 models.
- Vibration at specific RPM ranges – Uneven wear on the spur gear causes harmonic vibrations that resonate through the 4699301146: HOUSING, often felt in the operator cab.

Compatibility
This spur gear is engineered for ZF WG-series transmissions with mechanical PTO drives. Primary compatibility includes the WG100, WG130, and WG131 models, where it functions as the primary drive gear for auxiliary hydraulic pumps. It is also used in select WG180 and WG200 configurations that share the same gear train architecture. The part integrates with the 4699309085: HOUSING COVER to seal the gear chamber and is secured using the 0636101411: CAP SCREW for precise axial retention. Always verify your transmission’s serial number against ZF’s parts catalog before installation.
