Overview
The ZF 4460.308.383 SLIDING PAD is a critical wear component engineered for the WG200 series transmission. This OEM genuine part functions as a low-friction interface between the shift fork and the synchronizer sleeve, ensuring precise gear engagement and smooth axial movement within the transmission housing. The SKU 4460.308.383 is specifically designed to absorb lateral loads and reduce metal-on-metal contact during gear changes, directly impacting shift quality and drivetrain longevity. Installed within the selector mechanism, this sliding pad works in concert with the 4460165051: CONSOLE and the 4460368311: CONSOLE to maintain proper alignment of the shift rail assembly.
Symptoms of Failure
When the ZF 4460.308.383 sliding pad deteriorates, operators will notice distinct performance degradation. Hard shifting or gear clash occurs when the worn pad no longer provides adequate cushioning between components, causing abrupt engagement. Metallic grinding noises during gear selection indicate the pad material has been compromised, allowing direct metal contact. Intermittent gear slippage under load is a common symptom, as the worn pad cannot maintain consistent pressure on the synchronizer. Increased transmission oil contamination from accelerated wear debris is another telltale sign, often accompanied by reduced shift fork travel precision. These failure symptoms directly affect the 0636011429: HEXAGON SCREW and 0730100365: WASHER securing the assembly, potentially causing fastener loosening over time.

Compatibility
This sliding pad is primarily designed for the ZF WG200 series transmissions, including the WG200, WG180, and WG210 variants used in medium-duty commercial vehicles and off-highway equipment. The 4460.308.383 part is also compatible with select ZF Ecomat and Ecolife models that share the same shift fork architecture. For WG200 series applications, this component interfaces directly with the 4644105418: DISCONNECTION mechanism and the 4644305041: ADAPTER to ensure proper torque transfer. Always verify your transmission serial number against ZF technical bulletins before installation, as revisions to the 4460068159: AXLE DRIVE and 4460168651: INPUT FLANGE may affect pad clearance.
