ZF 0730.108.400 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.400 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within heavy-duty ZF construction machinery transmissions. This thin, hardened steel shim sits between the differential housing and bearing races, ensuring correct preload and gear mesh alignment. The SKU 0730.108.400 is a factory-original part, guaranteeing exact thickness tolerances for reliable torque transfer. When installed alongside a 5838109007: DIFFERENTIAL, this shim prevents unwanted lateral movement that can lead to premature wear on surrounding components.

Symptoms of Failure

When the ZF 0730.108.400 shim wears or deforms, operators will notice specific drivetrain disturbances. Look for these failure indicators to diagnose a worn shim:

• Excessive differential end-play: A clunking or knocking sound from the transmission housing during acceleration or deceleration, indicating the 2095209019: DIFFERENTIAL is shifting axially.
• Oil contamination from metal debris: Fine metallic particles in the transmission fluid, caused by the shim surface breaking down and grinding against the 0750117075: TAPER ROLLER BEARING race.
• Intermittent gear slippage: A momentary loss of drive power under load, as incorrect shim thickness alters clutch pack clearances and hydraulic pressure.
• Vibration at low speeds: A rhythmic shudder felt through the chassis when maneuvering in tight spaces, often misdiagnosed as a failing 0631329086: SPRING PIN.

Technical Specifications

Compatibility

This shim is a standard adjustment component used across multiple ZF powershift transmission families. It is commonly specified for the WG180, WG200, and WG210 series, as well as the 4WG-200 and 6WG-200 variants found in wheel loaders, graders, and dozers. The 0.40 mm thickness is typically employed as a fine-tuning shim between the differential carrier and the taper roller bearing cone. Always verify stack height requirements when replacing a 5838300817: THRUST WASHER or 5838300682: DIFFERENTIAL AXLE in the same assembly.
