ZF 4657.354.016 FLANGE for WG190/WG210 | OEM Genuine Part

Overview

The ZF 4657.354.016 FLANGE is a critical OEM genuine component engineered for the WG190 and WG210 series transmissions. This precision-machined flange serves as the primary interface between the transmission output shaft and the driveline, ensuring secure torque transfer and maintaining proper alignment within the powertrain assembly. As a factory-spec replacement, the SKU 4657.354.016 guarantees exact fitment and durability under high-load industrial applications. This flange is mounted directly to the output housing, working in concert with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to seal the transmission system against contaminants and pressure loss.

Symptoms of Failure

• Transmission fluid leaking from the output shaft area: A worn or cracked flange often results in visible oil seepage around the rear of the transmission, a common long-tail search query for “ZF WG190 flange oil leak fix.”
• Vibration or driveline shudder during acceleration: When the flange splines wear, rotational play develops, causing noticeable gear slipping or shudder under load, frequently searched as “ZF WG210 driveline vibration causes.”
• Abnormal noise from the transmission rear section: A loose flange produces a distinct clunking or metallic rattle during gear changes, often leading technicians to search for “ZF transmission output flange noise diagnosis.”
• Difficulty maintaining gear engagement: Severe flange wear can misalign the output shaft, leading to intermittent gear slipping or hard shifting, a symptom often queried as “ZF WG190 gear engagement problems.”

Technical Specifications

Compatibility

This flange is specifically designed for the ZF WG190 and WG210 series transmissions. Based on its spline configuration and mounting pattern, it is also compatible with the WG180, WG200, and select WG220 models that share the same output shaft architecture. For precise fitment, always verify the housing condition by inspecting the HOUSING REAR PART and the CYLINDRICAL PIN alignment during installation.

Frequently Asked Questions

Q: How do I know if the ZF 4657.354.016 flange is the correct replacement for my WG210 transmission?
A: Verify the spline count (24 internal splines) and the bolt circle diameter (130 mm). Additionally, inspect the condition of the HOUSING REAR PART for any cracks or wear that could affect flange seating.

Q: Can I reuse the old bolts when installing this flange?
A: No. ZF recommends replacing all fasteners, including the CAP SCREW and CAP SCREW (M12), to ensure proper torque retention and prevent future loosening.

Q: What is the typical lifespan of this flange under normal operating conditions?
A: With proper installation and regular transmission fluid maintenance, the OEM genuine flange typically lasts 500,000 to 800,000 kilometers. Early failure is often linked to misalignment of the CYLINDRICAL PIN or damage to the TRANSMISSION HOUSING.
