ZF 0634.319.247 SHAFT SEAL for WG65 | OEM Genuine Part

Genuine ZF SHAFT SEAL (Part No. 0634.319.247). This part fits: 4 WG 65. Found in: Output. Also referenced as: 0634319247 / 0634.319.247 / 0634 319 247.

Overview

The ZF 0634.319.247 SHAFT SEAL is a critical component engineered for the WG65 and WG200 series transmissions. This OEM genuine part ensures a leak-proof barrier around the rotating shaft, preventing transmission fluid from escaping while blocking contaminants from entering the gearbox. Positioned at the output shaft interface, this seal maintains hydraulic pressure essential for smooth gear engagement. The SKU 0634.319.247 is precision-machined to OEM tolerances, directly replacing worn seals in the TRANSMISSION HOUSING assembly. When installed alongside the HEXAGON SCREW (0636011038) and HEXAGON SCREW (0636011118), it forms a robust sealing system that extends transmission service life.

Symptoms of Failure

  • Transmission fluid puddling under the vehicle – A worn shaft seal allows oil to weep past the shaft, leaving visible drips or stains on the ground near the bell housing.
  • Low fluid level without external hose leaks – If the dipstick shows a gradual drop in ATF but no line leaks are visible, the 0634.319.247 seal is likely bypassing fluid into the torque converter area.
  • Whining or grinding noise from the output shaft – As the seal lip hardens or cracks, it can allow debris into the bearing area, causing audible friction during acceleration or deceleration.
  • Gear engagement delay or harsh shifting – A failing seal reduces hydraulic pressure, leading to sluggish clutch pack application and erratic shift quality.

Compatibility

This shaft seal is specifically designed for ZF WG65 and WG200 series transmissions, including the WG180, WG200, and WG65 variants. It fits output shaft housings in both 2-speed and 4-speed configurations. The 0634.319.247 seal is also compatible with certain ZF Ecomat and Ecolife models that share the same shaft diameter and housing bore. Always verify the HEXAGON SCREW (0636016015) torque specifications when reinstalling the housing cover.
