Overview
The ZF 2093.309.019 PLANETARY GEAR is a critical power-distribution component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the planetary gearset assembly, this genuine OEM part transfers torque from the sun gear to the carrier, enabling smooth ratio changes under heavy loads. The SKU 2093.309.019 ensures precise meshing with adjacent gears, reducing backlash and extending service life in demanding industrial drivelines. When installed alongside a 2093109001: DIFFERENTIAL, this planetary gear maintains consistent power flow through the final drive.
Symptoms of Failure
- Whining or grinding noise during acceleration: Worn planetary gear teeth create a high-pitched whine that intensifies under load, often misdiagnosed as bearing noise.
- Intermittent gear slipping under torque: A failing 2093.309.019 allows the planetary carrier to skip, causing sudden RPM spikes without corresponding speed increase.
- Metallic debris in transmission fluid: Flaking or pitting on the gear face releases ferrous particles that contaminate the oil, often visible during drain intervals.
- Vibration at steady highway speeds: Uneven wear on the planetary gear causes harmonic vibration that resonates through the driveline, particularly in WG130 models.

Compatibility
This planetary gear is factory-specified for the ZF WG100, WG130, and WG131 powershift transmissions. It also fits select WG180 and WG200 variants when used with the correct carrier assembly. For differential-side applications, pair it with a 2093209095: DIFFERENTIAL and 2093309071: DIFF.HOUSING to ensure proper alignment. Always verify the 0750117075: TAPER ROLLER BEARING condition when replacing this gear, as bearing preload directly affects gear mesh.

Frequently Asked Questions
Q: Can I use the 2093.309.019 in a WG200 transmission?
A: Yes, but only if the planetary carrier has the same spline count and bore diameter. Always compare the original part against the WG200 service manual to confirm compatibility.
Q: How do I know if the planetary gear is worn without disassembly?
A: Listen for a rhythmic clicking sound during deceleration, and check the transmission fluid for fine metallic glitter. Both indicate tooth surface fatigue on the 2093.309.019.
Q: Should I replace the taper roller bearing at the same time?
A: Absolutely. The 0750117075: TAPER ROLLER BEARING directly supports the planetary gear; reusing an old bearing can cause premature failure of the new gear due to misalignment.
