ZF 0730.108.402 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.402 SHIM is a precision-engineered OEM genuine part designed to establish the correct axial clearance and preload within heavy-duty ZF transmission assemblies. Positioned between rotating components and housing surfaces, this shim compensates for manufacturing tolerances and wear, ensuring optimal gear mesh and bearing support. The SKU 0730.108.402 is critical for maintaining the structural integrity of the transmission stack, particularly in construction machinery applications where high torque and shock loads are common. When paired with a 5838109007: DIFFERENTIAL or a 0750117075: TAPER ROLLER BEARING, this shim prevents axial movement that could lead to premature component failure.

Symptoms of Failure

When the ZF 0730.108.402 shim wears or is incorrectly installed, specific operational issues arise. Watch for these failure symptoms:

• Excessive end-play in the transmission shaft – A worn shim allows axial movement, causing a noticeable clunking sound during gear engagement or direction changes.
• Oil leaks from the differential housing – Incorrect shim thickness distorts seal alignment, leading to fluid seepage around the output flange.
• Gear slipping under load – Loss of preload reduces clutch pack clamping force, resulting in intermittent power loss during heavy excavation.
• Vibration at specific RPM ranges – A collapsed shim creates uneven bearing loading, transmitting resonance through the driveline.

Technical Specifications

Compatibility

This shim is a factory-fit component for several ZF heavy-duty transmission models commonly used in construction machinery. It is specifically validated for the WG180, WG200, and WG250 series. Additionally, it appears in the 4WG-200 and 5WG-180 variants where precise axial shimming of the differential carrier is required. Always verify stack height when replacing a 2095209019: DIFFERENTIAL or a 0631329086: SPRING PIN to ensure the shim pack matches the original specification.
