Overview
The ZF 2097.310.019 PLANETARY GEAR is a critical OEM genuine component engineered for the WG100, WG130, and WG131 transmission series. This precision-machined gear sits within the planetary gear set assembly, where it manages torque distribution and rotational speed reduction between the input shaft and the differential housing. As a genuine ZF part, SKU 2097.310.019 ensures exact fitment and metallurgical consistency, directly supporting the load-bearing capacity of the entire drivetrain. When installed alongside the 2093109021: DIFFERENTIAL, this planetary gear maintains synchronized power flow through the transmission’s final drive stages.
Symptoms of Failure
- Whining or grinding noise during gear engagement — A worn planetary gear produces a distinct high-pitched whine or metallic grinding sound, especially under load or when shifting between forward and reverse. This often indicates pitting or spalling on the gear teeth.
- Intermittent gear slipping under acceleration — When the planetary gear loses its tooth profile integrity, the transmission may momentarily lose torque transfer, causing a slipping sensation during highway merging or uphill climbs.
- Metallic debris in transmission fluid — Flakes or small fragments found during oil changes signal advanced wear of the planetary gear’s hardened surfaces, often accompanied by reduced hydraulic pressure.
- Vibration through the chassis at specific RPMs — Uneven wear on the planetary gear’s carrier can induce harmonic vibrations that resonate through the vehicle frame, typically between 1500–2500 RPM.

Compatibility
This planetary gear is specifically designed for ZF’s WG-series powershift transmissions. It is a direct replacement for the following models: WG100, WG130, and WG131. These transmissions are commonly found in medium-duty construction equipment, agricultural tractors, and material handlers. For proper assembly, this gear interfaces with the 2093209096: DIFFERENTIAL and the 2093309073: DIFF.HOUSING. Always verify your transmission serial number before ordering.

Frequently Asked Questions
Q: Can I use this planetary gear in a ZF WG180 transmission?
A: No. The 2097.310.019 is engineered exclusively for WG100, WG130, and WG131 models. The WG180 uses a larger planetary carrier with different tooth counts and spline dimensions.
Q: Should I replace the taper roller bearing when installing this gear?
A: Yes. ZF recommends replacing the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings accelerate planetary gear wear due to misalignment.
Q: How do I confirm this is an OEM genuine part?
A: Verify the part number 2097.310.019 is laser-etched on the gear’s inner bore. Genuine ZF parts also include a holographic label on the packaging with a batch code.
