ZF 0730.007.569 SHIM | OEM Genuine Part

Overview

This ZF 0730.007.569 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty construction machinery transmissions. Positioned between the differential housing and the bearing race, this shim compensates for manufacturing tolerances and thermal expansion, ensuring optimal gear mesh alignment. The SKU 0730.007.569 is specifically calibrated to maintain preload on the 0750117075 TAPER ROLLER BEARING, preventing lateral shaft movement that can lead to premature wear. Without this shim, the entire differential assembly—including the 5838109012 DIFFERENTIAL—would experience excessive end-play, compromising torque transfer efficiency.

Symptoms of Failure

• Transmission oil seepage at axle seals: A worn shim allows the differential housing to shift, distorting seal contact surfaces and causing slow oil leaks around the 5838300626 DIFFERENTIAL HOUSING.
• Intermittent gear slipping under load: When the shim thickness degrades, the 2093209023 DIFFERENTIAL loses proper backlash, causing momentary power loss during heavy excavation.
• Metallic grinding noise from the transmission center section: Insufficient shim clearance creates metal-on-metal contact between the bevel gear and the housing, producing a distinct low-frequency rumble during deceleration.
• Vibration in the driveline at highway speeds: Axial play from a collapsed shim induces harmonic oscillations that resonate through the chassis, often misdiagnosed as a driveshaft imbalance.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly used in wheel loaders, graders, and excavators. It is a direct fit for the following ZF models: WG180, WG200, 4WG180, 4WG200, 6WG180, and 6WG200 series. The 0730.007.569 is also compatible with select ZF differential assemblies found in agricultural tractors (e.g., T-7000 series) where the 5838300721 AXLE BEVEL GEAR is used. Always verify the shim stack height against the service manual when replacing the 5838300633 AXLE or associated thrust washers.

Frequently Asked Questions

Q: Can I reuse the 0730.007.569 shim after a differential rebuild?
A: No. This shim is a selective-fit component that deforms plastically during initial torque application. Always install a new OEM shim to maintain the precise preload on the taper roller bearing.

Q: How do I measure the correct shim thickness for my ZF WG200?
A: Use a depth micrometer to measure the bearing bore depth in the differential housing, then subtract the bearing width. The 0730.007.569 is a standard 1.50 mm shim; if your clearance exceeds 0.10 mm, stack multiple shims or select a thicker variant from the ZF service range.

Q: Will this shim fit the ZF 4WG180 transmission?
A: Yes. The 0730.007.569 is dimensionally identical for the 4WG180, 4WG200, and 6WG series. However, always cross-reference your transmission serial number with the ZF parts catalog to confirm the shim stack height specification.
