ZF 0730.006.999 SHIM | OEM Genuine Part

Overview

This genuine ZF 0730.006.999 SHIM is a precision-engineered spacer component designed to establish exact axial clearances within heavy-duty transmission assemblies. Positioned between the differential housing and bearing races, this shim compensates for manufacturing tolerances and thermal expansion, ensuring optimal gear mesh patterns. The SKU 0730.006.999 is a factory-original part critical for maintaining load distribution across the drivetrain. When installed alongside a 5838300626: DIFFERENTIAL HOUSING, it prevents metal-to-metal contact that accelerates wear on adjacent components.

Symptoms of Failure

• Excessive drivetrain backlash – Worn shims allow axial play, causing a noticeable clunk when shifting between forward and reverse gears.
• Premature bearing noise – A grinding or whining sound from the transmission center section indicates the 0750117075: TAPER ROLLER BEARING is losing preload due to incorrect shim thickness.
• Oil contamination from metal particles – Flattened shims shed debris into the lubricant, visible as glitter in the oil filter or drain plug.
• Intermittent gear slipping under load – When the shim stack collapses, the 5838109012: DIFFERENTIAL loses alignment, causing momentary power loss during excavation or grading.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG250 models used in wheel loaders, dozers, and telehandlers. The 0730.006.999 also applies to certain ZF ERGOPOWER and ECOMIX transmissions where the 2093209023: DIFFERENTIAL assembly requires precise shimming. Always verify your transmission serial number before ordering, as stack height tolerances vary between early and late production units.

Frequently Asked Questions

Q: Can I reuse the 0730.006.999 shim during a rebuild?
No. This shim is a single-use crush-type component. Reusing it will result in incorrect preload on the taper roller bearing, leading to rapid failure of the differential assembly.

Q: How do I measure the correct shim stack height?
Use a dial indicator to measure the axial play between the differential housing and bearing cup. Subtract the measured clearance from the target preload value (typically 0.05–0.10 mm for WG transmissions) to determine the required shim thickness.

Q: Will this shim fit a ZF 4WG-200 transmission?
Yes, the 0730.006.999 is compatible with the 4WG-200, 4WG-210, and 5WG-200 series. Always cross-reference your transmission’s parts manual to confirm stack configuration.
