Overview
The ZF 4656.309.005 FLANGE is a critical OEM genuine component engineered specifically for the WG160 transmission series. This precision-machined flange serves as the primary interface between the output shaft and the driveline, ensuring secure torque transfer and maintaining proper alignment within the gearbox assembly. As a direct replacement part, SKU 4656.309.005 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and long service life when paired with other genuine components such as the 4656101031: TRANSMISSION HOUSING and the 4656201075: HOUS.FRONT SECT.
Symptoms of Failure
When the 4656.309.005 FLANGE begins to wear, operators may notice distinct performance issues. Common failure indicators include:
- Oil leaks at the output shaft seal – A worn flange surface can damage the seal lip, leading to visible transmission fluid drips beneath the vehicle.
- Driveline vibration during acceleration – Excessive flange run-out or spline wear causes rotational imbalance, felt as a shudder through the chassis.
- Gear engagement difficulty or slipping – Misalignment from a degraded flange can prevent the transmission from fully locking into gear, especially under load.
- Metallic debris in the transmission fluid – Flange fretting or cracking sheds fine metal particles, contaminating the oil and accelerating wear on internal parts like the 4656201036: HOUSING REAR PART.

Frequently Asked Questions
Q: Can I reuse the old bolts when installing the 4656.309.005 flange?
No. ZF recommends replacing all fasteners, such as the 0636100817: CAP SCREW, to ensure proper clamping force and prevent loosening during operation.
Q: How do I know if my WG160 needs a new flange?
Inspect for radial play at the output yoke, visible oil weeping around the seal, or a vibration that worsens with speed. These are clear signs the flange surface or splines have degraded.
Q: Is this flange compatible with the WG200 transmission?
Yes, the 4656.309.005 flange shares the same bolt pattern and spline count as the WG200 series, making it a direct fit for most applications. Always confirm with your existing part.
