Overview
The ZF 0730.110.383 SHIM is a precision-engineered spacer component designed to establish exact axial clearances within heavy-duty ZF transmission assemblies. Positioned between gear sets and bearing races, this OEM genuine part ensures that rotating elements maintain proper preload and alignment under extreme torque loads. The SKU 0730.110.383 is commonly found in the differential and final drive sections of construction machinery transmissions, where even micron-level tolerances directly impact drivetrain longevity. By compensating for manufacturing tolerances, this shim prevents metal-to-metal contact and distributes load evenly across adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.
Symptoms of Failure
When the ZF 0730.110.383 shim wears or deforms, three distinct failure modes emerge. First, excessive gear backlash in the differential becomes noticeable during directional shifts, causing a clunking sound from the axle housing. Second, premature taper roller bearing failure occurs as axial play increases, leading to rough rotation and metallic debris in the oil. Third, oil seepage from the differential housing joint develops because misaligned components compromise seal contact. Operators may also report intermittent gear slipping under load on steep grades, a symptom that worsens as the shim thickness degrades.

Compatibility
This shim is engineered for ZF powershift transmissions used in construction machinery, specifically the WG180, WG200, and WG210 series. It is also compatible with the 4WG-200 and 6WG-200 variants found in wheel loaders and graders. The 0730.110.383 shim directly interfaces with the 2093209023: DIFFERENTIAL assembly and the 5838300626: DIFFERENTIAL HOUSING. For complete axle rebuilds, always pair this shim with a new 0750117075: TAPER ROLLER BEARING to maintain factory preload specifications.

Frequently Asked Questions
Q: Can I reuse the 0730.110.383 shim during a rebuild?
A: No. This shim is a single-use crush-type component. Reusing it will not restore proper preload and will accelerate bearing wear. Always install a new OEM shim.
Q: How do I measure the correct shim thickness for my ZF transmission?
A: Use a dial indicator to measure axial play between the differential and housing after installing the taper roller bearing. Subtract the measured gap from the target preload value (typically 0.05–0.15 mm) to select the correct shim.
Q: Will this shim fit the ZF 4WG-200 transmission?
A: Yes. The 0730.110.383 is a standard service part for the 4WG-200, 6WG-200, and WG210 series. Always verify your differential housing part number against the 5838300626: DIFFERENTIAL HOUSING for exact fitment.
