ZF 0730.008.568 SHIM | OEM Genuine Part

Overview

The ZF 0730.008.568 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within heavy-duty ZF transmissions used in construction machinery. This shim sits between the differential housing and the crown wheel assembly, ensuring correct gear mesh alignment and preload settings. The SKU 0730.008.568 is specifically calibrated to compensate for manufacturing tolerances, preventing metal-to-metal contact and maintaining optimal load distribution across the drivetrain. Without this shim, the entire differential assembly—including the 2099109038: DIFFERENTIAL and 2098309008: CROWN WHEEL—would experience accelerated wear due to improper backlash.

Symptoms of Failure

• Excessive gear whine or howling during acceleration: When the shim wears or compresses beyond tolerance, the 2098209016: DIFFERENTIAL gears lose correct mesh depth, producing a distinct high-pitched noise under load.
• Oil leaks from the differential housing seal: A collapsed shim allows the 2095309059: DIFF.HOUSING to shift, distorting the seal surface and causing lubricant seepage.
• Intermittent gear slipping or clunking: Worn shim material creates axial play, leading to sudden disengagement of the crown wheel from the pinion during torque reversal.
• Vibration in the driveline at low speeds: Uneven shim thickness causes the differential carrier to wobble, transmitting vibration through the axle housing.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series transmissions commonly found in wheel loaders, telehandlers, and graders. It is a direct fit for the following ZF models: WG180, WG200, WG210, WG220, and WG240. The 0730.008.568 is also used in certain ZF 4WG-200 and 6WG-200 variants where the differential assembly requires precise axial adjustment. Always verify your transmission serial number before ordering, as shim stacks may vary by application.
