Overview
This genuine ZF 2093.304.052 GEAR is a critical component within the planetary gearset of the WG100, WG130, and WG131 transmissions. It functions as a precision-machined drive gear, transferring torque from the input shaft to the intermediate shaft assembly. Positioned within the main gear housing, this OEM part ensures smooth power flow and load distribution across the transmission’s gear train. The SKU 2093.304.052 is engineered to exact ZF tolerances, guaranteeing a direct fit and long service life when replacing worn components in heavy-duty industrial drivelines.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn 2093.304.052 gear often produces a distinct high-pitched whine or metallic grinding sound, especially under load or during deceleration, indicating tooth surface fatigue or pitting.
- Intermittent gear slippage or loss of power: When the gear teeth become excessively worn or chipped, the transmission may slip out of gear or fail to transmit full engine torque, causing erratic vehicle movement under heavy loads.
- Metallic debris in transmission fluid: Advanced gear wear sheds fine metal particles into the oil, which can be detected during routine fluid changes or via magnetic drain plugs, signaling internal gear degradation.
- Vibration through the driveline: Uneven tooth wear on this gear creates rotational imbalance, leading to noticeable vibration in the chassis or shift lever during operation at specific RPM ranges.

Compatibility
This gear is specifically designed for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with select variants of the WG180 and WG200 models when used in the same planetary gearset position. Always verify the tooth profile and shaft spline count against your existing part before installation. The gear interfaces directly with the 2093101016: HOUSING and the 2093301030: TRANSMISSION HOUSING, which must be inspected for wear during replacement. For proper identification, reference the 0730365092: TYPE PLATE on your transmission to confirm model compatibility. Secure the assembly using the 0631311009: GROOVED STUD for precise alignment.

Frequently Asked Questions
Q: How can I confirm the 2093.304.052 gear is the correct replacement for my transmission?
A: Check the tooth count (32 teeth) and outside diameter (98.4 mm) against your worn gear. Also, verify the transmission model via the 0730365092: TYPE PLATE to ensure compatibility with WG100, WG130, or WG131 series.
Q: Should I replace the housing or seals when installing this gear?
A: Yes, it is strongly recommended to inspect and replace the 2093101016: HOUSING if worn, along with the 0634801215: SEALING RING and 0634303144: O-RING to prevent fluid leaks and ensure proper gear alignment.
Q: What causes premature failure of this gear?
A: Common causes include inadequate lubrication, contamination from metal debris, or improper torque on the 0631311009: GROOVED STUD, which can lead to misalignment and accelerated tooth wear.
