Overview
The ZF 0730.005.316 SHIM is a precision-engineered adjustment component designed specifically for the WG 65 series transmission. This OEM genuine shim sits between the TRANSMISSION HOUSING and the planetary gear assembly, where it controls axial clearance and preload tolerances. By maintaining exact spacing, the 0730.005.316 ensures optimal gear mesh alignment and prevents unwanted movement within the clutch pack. This part is critical for restoring factory-specified end-play during rebuilds or overhauls of heavy-duty ZF transmissions.
Symptoms of Failure
- Excessive axial play in the output shaft: When the shim wears or compresses beyond tolerance, you may notice a distinct clunking sensation during gear engagement, especially under load.
- Premature clutch pack wear: Incorrect shim thickness leads to improper clutch clearance, causing slipping or harsh shifting in forward and reverse gears.
- Transmission oil contamination from metal debris: A degraded shim can shed fine metallic particles into the lubrication circuit, often detected during routine oil analysis.
- Vibration at highway speeds: Loss of precise spacing allows the planetary carrier to shift, creating driveline vibration that worsens with RPM changes.

Compatibility
This shim is engineered for the ZF WG 65 series, but its dimensions and load rating also make it suitable for adjacent models in the WG family. It is commonly used in WG65, WG80, WG120, WG150, WG180, and WG200 transmissions, particularly in applications requiring precise axial adjustment of the planetary carrier. Always verify stack height with a dial indicator during installation, as multiple shims may be combined to achieve the specified clearance. For secure mounting, pair this shim with a HEXAGON SCREW and ensure the HOUSING or HOUSING surfaces are clean and free of burrs before assembly.
