ZF 0730.100.908 ADJUSTMENT PLATE for WG200 | OEM Genuine Part

Overview

The ZF 0730.100.908 ADJUSTMENT PLATE is a precision-machined shim component engineered for the WG200 series transmission. This OEM genuine part ensures correct axial clearance and preload within the clutch pack assembly, directly influencing shift timing and torque transfer efficiency. Installed between the piston and the clutch drum, the adjustment plate compensates for manufacturing tolerances, preventing premature wear on adjacent assemblies. The SKU 0730.100.908 is a factory-specified replacement for maintaining factory-specified end-play tolerances.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn adjustment plate reduces clutch pack clamping force, causing hesitation when shifting from Neutral to Drive or Reverse.
• Intermittent gear slipping under load: When the plate loses its precise thickness, the transmission may momentarily lose torque transfer during uphill climbs or heavy hauling.
• Low hydraulic pressure warnings: Excessive clearance from a deformed plate can cause internal fluid bypass, triggering diagnostic trouble codes for pressure regulation.
• Metallic debris in transmission fluid: A fatigued adjustment plate can fracture, introducing fine metal particles that contaminate the valve body and cooler lines.

Technical Specifications

Compatibility

This adjustment plate is primarily designed for the WG200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with select ZF off-highway and marine gearboxes that share the same clutch drum geometry. Always verify the part number against your transmission’s serial plate before installation. For complete assembly, pair this plate with the 4644105417 DISCONNECTION unit and either the 4644303547 OUTPUT FLANGE or the 4644303012 OUTPUT FLANGE depending on your driveline configuration. The 4644101121 TRANSMISSION HOUSING provides the structural envelope for these components.
