Overview
The ZF 0730.002.205 SHIM is a precision-engineered spacer component designed for the WG 200 Series transmission. This OEM genuine part sits between the transmission housing and the output flange assembly, where it establishes critical axial clearance and preload tolerances. By maintaining exact spacing, the SKU 0730.002.205 prevents metal-on-metal contact and ensures smooth torque transfer across the drivetrain. When paired with a TRANSMISSION HOUSING, this shim compensates for thermal expansion and manufacturing variances, extending the service life of the entire gear train.
Symptoms of Failure
- Oil seepage at the output shaft seal: A worn 0730.002.205 shim allows the output flange to shift, breaking the seal contact and causing transmission fluid to weep from the rear housing.
- Audible gear whine under load: Incorrect shim thickness leads to excessive gear backlash, producing a high-pitched whining noise during acceleration or hill climbing.
- Vibration in the driveline at highway speeds: When the shim compresses unevenly, the output shaft loses concentricity, transmitting vibrations through the OUTPUT FLANGE to the driveshaft.
- Intermittent gear slipping in reverse: Axial play from a collapsed shim reduces clutch pack engagement pressure, causing momentary power loss when shifting into reverse.

Compatibility
This shim is engineered for the ZF WG 200 Series transmission family, including models WG180, WG200, and WG210. It is also compatible with select off-highway variants used in agricultural tractors and construction loaders. The 0730.002.205 works in conjunction with the DISCONNECTION assembly and is secured using a HEXAGON SCREW to maintain proper clamping force. Always verify your transmission serial number before installation.
