Overview
The ZF 4460.308.384 SLIDING PAD is a critical wear component engineered specifically for the WG 200 Series transmission. This OEM genuine part functions as a low-friction interface within the clutch pack assembly, reducing metal-on-metal contact during gear shifts. Positioned between the shift cylinder and the selector mechanism, the sliding pad ensures smooth axial movement and precise engagement. The SKU 4460.308.384 is manufactured to ZF’s exacting tolerances, guaranteeing consistent hydraulic pressure distribution and extended service life in heavy-duty industrial applications.
Symptoms of Failure
- Erratic gear engagement or delayed shifting: When the sliding pad wears unevenly, the transmission may hesitate or clunk during gear changes, particularly under load.
- Hydraulic fluid contamination: A degraded pad can shed polymer particles into the oil circuit, causing valve body blockages and erratic pressure readings.
- Increased operating noise: Worn pads produce a distinct metallic scraping sound from the shift housing, especially during low-speed maneuvers.
- Premature wear of adjacent components: A failing sliding pad accelerates damage to the 4460165051 CONSOLE and 4460368311 CONSOLE, leading to costly assembly replacements.

Compatibility
This sliding pad is a direct-fit component for the ZF WG180, WG200, and WG210 transmission series. It is also compatible with select Ecomat 4HP and 6HP variants that share the same shift cylinder architecture. Always verify the presence of the 0636011429 HEXAGON SCREW and 0730100365 WASHER during installation, as these fasteners must be replaced to maintain proper clamping torque. The pad interfaces directly with the shift fork guide rail and should be inspected alongside the 4460168651 INPUT FLANGE for optimal alignment.
