ZF 0730.304.067 SHIM | OEM Genuine Part

Overview

The ZF 0730.304.067 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within heavy-duty ZF transmissions used in construction machinery. This shim sits between the differential housing and the bearing race, ensuring that the gear train maintains exact preload tolerances during high-torque operation. The SKU 0730.304.067 is manufactured to factory specifications, providing a reliable solution for restoring transmission geometry without replacing entire assemblies. When installed alongside a 5838109012: DIFFERENTIAL, this shim compensates for wear and prevents axial movement that can lead to premature component fatigue.

Symptoms of Failure

When the ZF 0730.304.067 SHIM wears or becomes compressed beyond its service limit, operators may notice specific drivetrain irregularities. Excessive backlash in the final drive is a primary indicator, often accompanied by a clunking noise during direction changes. Oil seepage from the axle housing seal can occur as the shim loses thickness, allowing the bearing to shift and distort the seal lip. Intermittent gear slipping under load becomes apparent when the shim fails to maintain proper pinion depth, particularly during heavy excavation cycles. Vibration at the wheel hub at low speeds signals that the shim stack no longer provides adequate preload to the 0750117075: TAPER ROLLER BEARING, allowing radial play to develop.

Technical Specifications

Compatibility

This shim is engineered for ZF power shift transmissions commonly deployed in wheel loaders, dozers, and graders. It is a direct fit for the ZF WG180, WG200, and WG210 series, as well as the 4WG-200 and 6WG-200 variants. The 0730.304.067 is also used in certain ZF Ergopower and ZF Ecomix drivelines where the differential assembly requires precise shimming. For complete axle rebuilds, this shim must be paired with a 2093209023: DIFFERENTIAL and a 5838300626: DIFFERENTIAL HOUSING to ensure correct bearing preload and gear mesh alignment.

Frequently Asked Questions

Q: How do I know if the 0730.304.067 shim needs replacement?
A: Measure the existing shim thickness with a micrometer. If it has compressed more than 0.08 mm below the nominal 0.50 mm, or if you observe any edge deformation, replacement is required to restore proper bearing preload.

Q: Can this shim be reused after a differential rebuild?
A: No. ZF recommends installing a new 0730.304.067 shim during any differential or bearing service. The shim undergoes plastic deformation during initial torque application and cannot reliably maintain clearance after removal.

Q: Is this shim compatible with aftermarket differential housings?
A: The shim is dimensionally matched to OEM ZF housings. If using a non-OEM housing, you must verify the inner and outer diameters (42.0 mm and 68.0 mm) and stack height requirements before installation.
