ZF 0730.108.394 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.394 SHIM is a precision-engineered OEM genuine spacer component designed for critical axial clearance management within heavy-duty ZF powershift transmissions. This shim sits between the differential housing and bearing raceways, ensuring correct preload on rotating assemblies. The SKU 0730.108.394 is manufactured to exact factory tolerances to prevent lateral movement of gear sets. When installed alongside a 5838109007: DIFFERENTIAL, this shim maintains proper gear mesh depth and load distribution across the planetary system.

Symptoms of Failure

• Excessive differential end-play: A worn or collapsed shim causes measurable axial movement in the differential carrier, leading to “clunking” noises during direction changes.
• Premature taper roller bearing failure: Incorrect shim thickness creates improper preload on the 0750117075: TAPER ROLLER BEARING, resulting in overheating and brinelling of raceways.
• Oil contamination from metal debris: As the shim wears, microscopic steel particles enter the transmission fluid, causing accelerated wear on clutch packs and valve bodies.
• Intermittent gear slippage under load: Loss of shim thickness alters the pinion depth relative to the 2095209019: DIFFERENTIAL, reducing torque transfer efficiency.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF WG-series powershift transmissions commonly found in construction machinery. It is a direct fit for the following models:

• ZF WG180 (all variants)
• ZF WG200 (series 2 and 3)
• ZF WG210 (early production)
• ZF 4WG-200
• ZF 6WG-250

Always verify shim stack height using a depth micrometer when replacing the 0631329086: SPRING PIN that retains the differential assembly.
