Overview
The ZF 0730.103.723 ADJUSTMENT PLATE is a precision-machined shim component engineered for the WG 200 Series transmission family. This OEM genuine part, identified by SKU 0730.103.723, sits between the TRANSMISSION HOUSING and the clutch pack assembly to establish correct axial clearance and preload. By controlling end-play tolerances, this adjustment plate ensures consistent hydraulic pressure distribution across the rotating elements. Without this critical spacer, the transmission cannot maintain proper gear engagement or torque transfer under load.
Symptoms of Failure
- Delayed or harsh shifting – When the adjustment plate wears or deforms, clutch pack clearance increases, causing noticeable lag between gear changes or abrupt engagement.
- Low hydraulic pressure warnings – A worn 0730.103.723 plate allows excessive axial movement, leading to pressure drops in the main circuit that trigger dashboard alerts.
- Metallic debris in transmission fluid – Friction between the plate and adjacent components generates fine metal particles, visible during fluid changes or filter inspections.
- Intermittent gear slipping under load – As clearance grows beyond specification, the transmission may momentarily lose torque transfer when climbing grades or towing heavy loads.

Compatibility
This adjustment plate is designed primarily for the ZF WG200 transmission series, including models WG180, WG200, and WG210. It also fits select variants of the WG150 and WG250 where the clutch pack stack height matches the 2.50 mm shim specification. Always verify the OUTPUT FLANGE and OUTPUT FLANGE part numbers against your transmission serial plate before installation. The plate works in conjunction with the DISCONNECTION mechanism to ensure proper clutch separation during neutral-to-drive shifts.
