ZF 0730.113.224 SHIM | OEM Genuine Part

Overview

The ZF 0730.113.224 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within ZF heavy-duty transmissions. This shim sits between the differential housing and the crown wheel assembly, ensuring that gear mesh patterns remain within factory tolerances. By adjusting the preload on the differential bearings, the 0730.113.224 directly influences drivetrain stability and load distribution. As a thin, hardened steel spacer, it compensates for manufacturing tolerances and prevents unwanted movement of internal components. The SKU 0730.113.224 is specifically calibrated for use in construction machinery transmissions where high torque and shock loads are common.

Symptoms of Failure

• Excessive differential backlash – When the shim wears or compresses beyond spec, you will notice a clunking sound during direction changes, especially under load. This is a classic sign of lost axial preload.
• Oil leaks near the axle housing – A worn shim allows the differential assembly to shift, distorting the seal surface against the DIFFERENTIAL HOUSING. This creates gaps that lead to gear oil seepage.
• Premature crown wheel wear – Incorrect shim thickness alters the contact pattern between the CROWN WHEEL and pinion, resulting in uneven tooth wear and increased operating noise.
• Vibration during acceleration – A collapsed shim causes the DIFFERENTIAL to wobble, transmitting vibration through the driveline that worsens as speed increases.

Technical Specifications

Compatibility

This shim is a standard adjustment component used across multiple ZF transmission families. It is commonly found in the WG180, WG200, and WG250 series, as well as the ECOMIX and Powershift lines used in wheel loaders, graders, and dump trucks. The 0730.113.224 is also employed in the differential section of the ZF 4WG-200 and ZF 6WG-250 transmissions. When replacing this shim, always inspect the mating DIFFERENTIAL assembly for scoring or fretting, as a damaged counterface will quickly ruin a new shim.
