ZF 0730.007.983 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.983 SHIM is a precision-engineered OEM genuine component designed for critical axial clearance adjustment within heavy-duty ZF powershift transmissions. This thin, hardened steel shim sits between the differential housing and bearing races to establish the correct preload and end-play tolerances. Without the exact thickness provided by the 0730.007.983, gear mesh patterns shift, leading to accelerated wear. This SKU is frequently selected during rebuilds of construction machinery transmissions to restore factory-specified backlash and prevent premature failure of adjacent rotating assemblies.

Symptoms of Failure

• Excessive differential end-play: When the 0730.007.983 shim compresses or corrodes, you will feel a distinct clunking sensation from the driveline during direction changes, especially in wheel loaders and graders.
• Oil contamination from metal debris: A worn shim allows the 2095109016 DIFFERENTIAL to contact the housing, generating fine metallic particles visible in the transmission oil filter.
• Intermittent gear slipping under load: Incorrect shim thickness alters the preload on the 0750117075 TAPER ROLLER BEARING, causing momentary loss of torque transfer when the machine digs or pushes heavy material.
• Vibration at specific RPM ranges: A collapsed shim creates harmonic resonance in the 2095209037 DIFFERENTIAL assembly, felt as a low-frequency shudder through the chassis.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG211 series, as well as the 4WG-200 and 5WG-180 variants. The 0730.007.983 is also used in select ERGO-POWER and ECOMIX drivelines. Always verify the shim stack height when replacing the 2095309059 DIFF.HOUSING, as housing wear can alter the required clearance.
