ZF 0730.113.223 SHIM | OEM Genuine Part

Overview

The ZF 0730.113.223 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within the differential assembly of heavy-duty construction machinery transmissions. This thin, hardened steel component sits between the differential housing and the bearing races, ensuring that gear mesh patterns remain within factory tolerances. By maintaining the correct preload on the 2099109002: DIFFERENTIAL and the 2099364014: CROWN WHEEL, the SKU 0730.113.223 prevents unwanted axial movement that leads to premature wear. Its role is often overlooked, yet it is fundamental to the longevity of the entire drivetrain assembly.

Symptoms of Failure

• Excessive drivetrain backlash – A worn or incorrectly sized shim allows the differential to shift, creating a noticeable clunk when shifting between forward and reverse gears.
• Abnormal gear whine from the axle – When the shim loses its thickness, the 2098309010: DIFFERENTIAL HOUSING no longer supports the crown wheel at the correct depth, producing a high-pitched whine under load.
• Uneven tire wear on construction equipment – A failing shim disrupts the differential lock-up sequence, causing one wheel to spin faster than the other during straight-line operation.
• Oil contamination with metallic debris – As the shim wears, fine steel particles enter the transmission fluid, often visible on the magnetic drain plug.

Technical Specifications

Compatibility

This shim is primarily used in ZF WG-series powershift transmissions found in wheel loaders, graders, and telehandlers. It is a direct fit for the WG180, WG200, and WG210 models. It also appears in certain ZF 4WG-200 and ZF 6WG-250 torque converter transmissions. Always verify the shim stack height when replacing the 2099209001: DIFFERENTIAL assembly, as multiple shims may be stacked to achieve the correct preload.
