Overview
This genuine OEM ZF 4657.309.015 FLANGE is a critical driveline component engineered specifically for the WG 210 Series transmission. It serves as the primary output interface, connecting the transmission’s rotating assembly to the driveshaft via a precision-machined splined bore. The flange ensures torque is transferred smoothly from the gearset to the vehicle’s wheels. The SKU 4657.309.015 is a direct replacement part, manufactured to ZF’s original tolerances for a secure, vibration-free fit. It mounts directly onto the output shaft and is sealed against the TRANSMISSION HOUSING to maintain internal lubrication integrity.
Symptoms of Failure
- Output shaft oil leaks: A worn flange seal or cracked flange face allows transmission fluid to weep past the CYLINDRICAL PIN interface, leaving puddles under the vehicle.
- Driveline vibration at highway speeds: When the flange’s pilot bore becomes scored or the splines wear, the driveshaft loses concentric alignment, causing rhythmic shaking.
- Clunking noise during acceleration or deceleration: Excessive backlash between the flange splines and the output shaft creates a metallic knock, often mistaken for a failing U-joint.
- Premature bearing wear in the rear section: A loose flange places axial load on the HOUSING REAR PART, accelerating bearing fatigue and generating metallic debris in the oil.

Compatibility
This flange is a direct fit for the ZF WG 210 Series transmission family. Based on its spline geometry and bolt pattern, it is also compatible with the WG 180, WG 200, and WG 250 series when used with the correct HOUS.FRONT SECT adapter. It is commonly found in off-highway trucks, wheel loaders, and agricultural tractors equipped with ZF powershift transmissions. Always verify the output shaft spline count before installation.

Frequently Asked Questions
Q: Can I reuse the old flange bolts when installing part 4657.309.015?
A: No. ZF specifies new CAP SCREW fasteners and a new FIXING PLATE to maintain proper torque retention and prevent flange walk-off.
Q: How do I know if my WG210 flange is worn beyond tolerance?
A: Measure the spline root diameter. If it exceeds 34.2 mm or shows visible step wear, the flange must be replaced to avoid output shaft damage inside the HOUSING REAR PART.
Q: Does this flange require a specific sealant during installation?
A: Yes. Apply a thin layer of Loctite 518 or equivalent anaerobic flange sealant to the mating face against the TRANSMISSION HOUSING to prevent external oil leaks.
