Overview
The ZF 0730.002.204 SHIM is a precision-engineered spacer component designed for the WG 200 Series transmission family. This OEM genuine part sits between the transmission housing and the output flange assembly, where it controls axial clearance and preload within the drivetrain. By maintaining exact tolerances, the shim ensures that rotating elements remain properly aligned under load. The SKU 0730.002.204 is a factory-specified shim that must be selected during rebuilds to restore factory-specified endplay. When installed alongside the 4644105424 DISCONNECTION and 4644303538 OUTPUT FLANGE, this shim prevents metal-to-metal contact and extends service life.
Symptoms of Failure
- Excessive axial play in the output shaft — A worn or incorrect shim allows the output flange to move fore and aft, causing driveline vibration and premature bearing wear.
- Oil seepage at the rear seal — When the shim loses thickness or cracks, the output flange shifts, breaking the seal contact and leading to transmission fluid leaks around the tail housing.
- Gear engagement noise under load — Insufficient preload from a collapsed shim permits gear train backlash, resulting in a distinct clunking sound during acceleration or deceleration.
- Overheating of the output bearing — Incorrect shim stack height creates excessive or insufficient bearing preload, generating heat and reducing transmission efficiency.

Compatibility
This shim is specifically engineered for the ZF WG 200 Series transmissions, including the WG180, WG200, and WG210 models. It is a critical component in the output shaft bearing preload stack and is used in both on-highway and off-highway applications. Always verify the shim thickness requirement using the factory service manual, as multiple thicknesses (0.30 mm to 1.00 mm) are available for selective assembly. The shim works in conjunction with the 4644303538 OUTPUT FLANGE and the 0636021036 HEXAGON SCREW to secure the assembly. Additionally, the 4644101224 TRANSMISSION HOUSING provides the mounting surface against which the shim seats.
