ZF 0730.110.008 SHIM | OEM Genuine Part

Overview

The ZF 0730.110.008 SHIM is a precision-engineered adjustment component designed to maintain critical axial clearances within ZF heavy-duty transmission assemblies. Positioned between the differential housing and bearing races, this OEM genuine shim ensures correct preload on the 0750117075: TAPER ROLLER BEARING and adjacent gear sets. The SKU 0730.110.008 directly controls backlash tolerances in the final drive section, preventing excessive gear movement that leads to premature wear. Without this shim, the transmission cannot maintain the precise load distribution required for high-torque construction machinery applications.

Symptoms of Failure

• Excessive differential bearing noise during turns: A worn or missing 0730.110.008 shim allows the 5838109012: DIFFERENTIAL to shift laterally, producing a low-frequency growl when the machine corners under load.
• Oil seepage at axle housing seals: Incorrect shim thickness causes the 5838300626: DIFFERENTIAL HOUSING to misalign, distorting seal contact surfaces and leading to chronic lubricant loss.
• Intermittent gear slipping under heavy load: When the shim stack loses its original thickness, the 2093209023: DIFFERENTIAL gears lose proper mesh engagement, causing momentary torque interruptions during excavation or lifting.
• Metallic debris in transmission fluid: Accelerated wear from improper shim clearance generates fine steel particles that contaminate the hydraulic circuit and clog filters.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly used in construction machinery. It is a direct fit for the WG180, WG200, and WG211 series final drives. The 0730.110.008 also appears in certain 4WG-200 and 5WG-300 transfer case assemblies where differential preload adjustment is required. Always verify the existing shim stack count before replacement, as multiple shims may be stacked to achieve the specified bearing preload on the 0750117075: TAPER ROLLER BEARING.

Frequently Asked Questions

Q: Can I reuse the 0730.110.008 shim during a differential rebuild?
A: No. ZF recommends replacing all shims with new OEM parts during any transmission overhaul. The shim compresses slightly under load and loses its original thickness, which alters bearing preload and gear backlash.

Q: How do I measure the correct shim thickness for my ZF transmission?
A: Use a dial indicator to measure the axial play between the differential housing and bearing race. Subtract the measured clearance from the factory specification (typically 0.05–0.10 mm preload) to determine the required shim thickness. Always stack shims on the non-drive side of the 5838300626: DIFFERENTIAL HOUSING.

Q: Will a thicker shim fix differential noise?
A: Only if the noise is caused by insufficient bearing preload. Installing an oversized shim can overload the 0750117075: TAPER ROLLER BEARING and cause rapid bearing failure. Always measure clearance before selecting the 0730.110.008 or any alternative shim.
