Overview
The ZF 0730.110.742 SHIM is a precision-engineered adjustment component designed to establish correct axial clearances within heavy-duty ZF transmissions. This OEM genuine part, identified by SKU 0730.110.742, is positioned between the differential housing and the bearing race to eliminate excessive end-play. By maintaining the precise preload on rotating assemblies, this shim ensures that power transfer remains smooth and vibration-free. In construction machinery applications, the 0730.110.742 shim works in concert with the 5838109012: DIFFERENTIAL to maintain gear mesh accuracy under extreme loads.
Symptoms of Failure
- Excessive differential backlash: When the shim compresses or wears, you will notice a clunking sound during direction changes, indicating the 0750117075: TAPER ROLLER BEARING has lost its preload.
- Oil leaks at the axle flange: A worn shim allows the differential housing to shift, breaking the seal and causing fluid seepage around the output shafts.
- Gear whine under load: Incorrect shim thickness alters the contact pattern between the ring and pinion gears, producing a high-pitched whine that worsens as the machine works harder.
- Premature bearing failure: Without the correct shim, the taper roller bearing experiences axial play, leading to brinelling and eventual seizure of the rotating assembly.

Compatibility
This shim is specifically engineered for ZF heavy-duty transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series. The 0730.110.742 also applies to the AP400 and AP500 axle assemblies. When replacing this shim, always inspect the 5838300626: DIFFERENTIAL HOUSING for wear, as housing distortion can accelerate shim failure. Additionally, verify the condition of the 2093209023: DIFFERENTIAL assembly to ensure proper alignment during reassembly.

Frequently Asked Questions
Q: How do I measure the correct shim thickness for my ZF transmission?
A: Use a dial indicator to measure the end-play of the differential assembly without the shim. Subtract the desired preload (typically 0.05-0.10 mm) from this measurement, then select the 0730.110.742 shim that matches the calculated thickness. Always stack shims on the non-drive side of the bearing.
Q: Can I reuse the 0730.110.742 shim after disassembly?
A: No. This shim is a single-use crush-type component. Reusing it will result in incorrect preload, leading to the failure symptoms described above. Always install a new OEM genuine shim during any differential or bearing service.
Q: Does this shim fit the ZF WG180 transmission with a locking differential?
A: Yes, the 0730.110.742 shim is compatible with both open and locking differential variants in the WG180 series. However, if your unit uses a locking mechanism, also inspect the 5838300818: THRUST WASHER for scoring, as lock-up engagement can cause additional axial stress on the shim stack.
