Overview
The ZF 4657.309.007 FLANGE is a critical driveline interface component engineered for the WG160, WG190, and WG210 series transmissions. This OEM genuine part, identified by SKU 4657.309.007, mounts directly to the output shaft housing, providing a secure coupling point for the propeller shaft. It ensures precise torque transfer from the transmission to the vehicle’s drivetrain. The flange works in concert with the 4656201075: HOUS.FRONT SECT and the 4656201035: HOUSING REAR PART to maintain structural integrity under heavy loads. Without this flange, the transmission cannot deliver rotational power to the wheels, making it indispensable for operational reliability.
Symptoms of Failure
- Transmission fluid seepage at the output shaft: A worn flange gasket surface or cracked metal allows oil to escape, often visible as drips under the vehicle near the rear of the gearbox.
- Vibration during acceleration or deceleration: A distorted or loose flange creates imbalance in the driveline, causing noticeable shaking that worsens at highway speeds.
- Clunking noise when shifting between drive and reverse: Excessive play in the flange splines leads to audible metallic impacts as torque direction changes.
- Difficulty maintaining gear engagement under load: A failing flange can cause the output shaft to wobble, leading to intermittent power loss or slipping sensations.

Frequently Asked Questions
Q: Can the 4657.309.007 flange be reused after removal?
A: It is not recommended. The flange undergoes stress during operation, and reusing it may lead to premature failure. Always install a new OEM part for optimal sealing and torque retention.
Q: Does this flange require a specific torque specification?
A: Yes. ZF specifies a tightening torque of 120 Nm for the mounting cap screws, applied in a cross pattern. Always consult your service manual for exact values.
Q: How do I know if my WG transmission uses this flange?
A: Check the transmission identification tag. If your model is WG160, WG190, or WG210, this part is compatible. For WG180 or WG200 variants, verify the output shaft spline count matches the flange bore.
