ZF 4644.354.014 PUMP FLANGE for WG200 | OEM Genuine Part

Overview

The ZF 4644.354.014 PUMP FLANGE is a critical OEM genuine component engineered specifically for the WG 200 Series transmission. This precision-machined flange serves as the primary mounting interface between the hydraulic pump and the transmission housing, ensuring correct alignment and oil flow. The SKU 4644.354.014 is designed to withstand high torsional loads and thermal cycling, directly supporting the pump drive mechanism. When installed alongside the 4460165051 CONSOLE and 4460368311 CONSOLE, this flange provides a rigid foundation for the entire pump assembly, preventing vibration-induced wear.

Symptoms of Failure

• Hydraulic oil seepage around the pump mounting area: A worn or cracked 4644.354.014 flange often leads to visible oil leaks at the transmission-pump junction, causing low fluid levels and erratic shifting.
• Abnormal pump noise or whining during operation: Misalignment from a damaged flange creates excessive stress on the pump shaft, producing audible whining or grinding sounds under load.
• Intermittent loss of hydraulic pressure: A warped or fatigued flange allows air ingress, resulting in spongy clutch engagement and delayed gear engagement in WG200 transmissions.
• Vibration transmitted through the chassis: When the flange fails to maintain concentricity, it induces harmonic vibrations that can be felt through the vehicle floor, particularly at idle.

Technical Specifications

Compatibility

This pump flange is primarily designed for the ZF WG 200 Series, including the WG200, WG210, and WG220 variants. It also fits select WG180 models where the pump mounting interface shares the same bolt pattern. Always verify the pump housing configuration before installation. For complete assembly, pair this flange with the 0636011429 HEXAGON SCREW and 0730100365 WASHER to ensure proper torque retention and sealing integrity.
