ZF 0730.002.218 SHIM | OEM Genuine Part

Overview

The ZF 0730.002.218 SHIM is a precision-engineered adjustment component designed to control axial play and preload within ZF heavy-duty transmission assemblies. This OEM genuine part, identified by SKU 0730.002.218, is strategically positioned between the differential housing and bearing races to ensure correct gear mesh alignment. By maintaining exact tolerances, this shim prevents excessive movement of rotating elements, directly influencing torque transfer efficiency in construction machinery drivetrains. When paired with a 5838109012: DIFFERENTIAL, it guarantees optimal load distribution across the axle assembly.

Symptoms of Failure

• Transmission whining noise under load: A worn or collapsed shim allows the differential to shift, creating abnormal gear contact patterns that produce a high-pitched whine during acceleration.
• Premature bearing wear: When the 0730.002.218 loses its calibrated thickness, the 0750117075: TAPER ROLLER BEARING experiences uneven loading, leading to rapid degradation and metal contamination in the oil.
• Oil seepage from axle seals: Excessive end float caused by a failed shim forces the differential housing to shift, compromising seal integrity and causing visible leaks around the output flanges.
• Vibration during low-speed maneuvering: A degraded shim permits axial movement of the gearset, resulting in noticeable shuddering when operating construction equipment in reverse or tight turns.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in wheel loaders, excavators, and telehandlers. It is a direct fit for the WG180, WG200, and WG211 series, where it adjusts the preload on the differential assembly. The 0730.002.218 also applies to the 4WG-200 and 5WG-180 variants used in construction machinery from manufacturers such as Liebherr, Volvo, and Caterpillar. For complete axle restoration, always replace this shim alongside the 2093209023: DIFFERENTIAL and the 5838300626: DIFFERENTIAL HOUSING to maintain factory backlash specifications.

Frequently Asked Questions

Q: How do I verify the correct thickness of the 0730.002.218 shim during installation?
A: Measure the existing end float using a dial indicator at the differential ring gear. Subtract the desired preload (typically 0.05-0.10 mm) from the measured gap, then select the shim thickness that matches that value. Always use a micrometer to confirm the shim’s actual thickness before assembly.

Q: Can I reuse this shim if it appears undamaged?
A: No. ZF recommends replacing all shims during a transmission overhaul. Even minor compression or edge wear alters the preload, leading to accelerated failure of the 0750117075: TAPER ROLLER BEARING and differential gears.

Q: Does this part fit the ZF 4WG-310 transmission?
A: The 0730.002.218 is not specified for the 4WG-310 series. That model uses a larger shim (0730.002.225). Always cross-reference your transmission serial number with the OEM parts catalog to ensure correct fitment.
