ZF 0730.109.380 SHIM | OEM Genuine Part

Overview

The ZF 0730.109.380 SHIM is a precision-engineered OEM genuine part designed to establish exact axial clearances and preload settings within heavy-duty ZF transmissions. This shim sits between the differential housing and bearing races, ensuring that gear mesh patterns remain within factory tolerances. The SKU 0730.109.380 is critical for maintaining the structural integrity of the drivetrain, particularly in construction machinery applications where shock loads are common. Without this shim, the entire assembly can experience misalignment, leading to accelerated wear on adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

When the ZF 0730.109.380 SHIM wears out or is incorrectly installed, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Excessive gear backlash and clunking noises – A worn shim allows the differential to shift, creating audible play during direction changes. This is a common long-tail search query for “ZF transmission clunking when shifting.”
• Premature bearing failure – Incorrect shim thickness alters preload on the 0750117075: TAPER ROLLER BEARING, leading to overheating and spalling.
• Oil leaks from the differential housing – A collapsed shim can distort the housing seal surface, causing fluid to weep around the 5838300626: DIFFERENTIAL HOUSING.
• Vibration under load – The driveline will vibrate at low speeds as the 2093209023: DIFFERENTIAL loses its proper alignment.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty transmissions commonly found in construction machinery. It is compatible with the following ZF models: WG180, WG200, WG210, and WG250 series. These transmissions are used in wheel loaders, graders, and telehandlers. The shim is also a direct fit for the differential assemblies in ZF 4WG-200 and 6WG-200 drivelines. For precise installation, always pair this shim with a new 0631329088: SPRING PIN to secure the assembly.

Frequently Asked Questions

Q: How do I know if the ZF 0730.109.380 shim thickness is correct for my transmission?
A: Always measure the existing shim stack and compare to the service manual specifications for your specific ZF model (e.g., WG200). The 0.38 mm thickness is a common baseline, but field adjustments may be required to achieve 0.05–0.15 mm of bearing preload.

Q: Can I reuse this shim during a rebuild?
A: No. The shim is a single-use component due to its crush-washer-like deformation during initial torqueing. Always install a new OEM 0730.109.380 shim and replace the 0631329088: SPRING PIN simultaneously.

Q: Will this shim fit the ZF 6WG-250 transmission?
A: Yes, the 0730.109.380 is dimensionally identical for the 6WG-250 differential housing. However, verify that your housing uses the 85 mm outer diameter seat; some early models used a 90 mm variant.
