ZF 0730.007.570 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.570 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within heavy-duty ZF transmissions. This shim sits between the differential housing and the bearing race, ensuring that gear preload and backlash remain within factory tolerances. The SKU 0730.007.570 is commonly specified during rebuilds of construction machinery transmissions, where even a 0.1mm deviation can lead to premature wear. By maintaining correct spacing, this shim directly supports the longevity of adjacent components such as the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Excessive differential end-play: When the shim wears or compresses, you will detect a noticeable clunk during direction changes, often searched as “ZF transmission differential play symptoms.”
• Oil leaks at the axle flange: A collapsed shim alters the housing alignment, causing seal distortion and fluid seepage—a common “ZF WG200 oil leak” complaint.
• Gear whine under load: Incorrect shim thickness disrupts the mesh pattern of the 2093209023: DIFFERENTIAL, producing a high-pitched noise during excavation or grading operations.
• Premature bearing failure: Without proper shim support, the taper roller bearing experiences uneven loading, leading to spalling and metallic debris in the oil pan.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions used in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series, where it regulates the axial position of the differential assembly. The part also appears in certain 4WG-200 and 5WG-180 variants. When replacing this shim, always inspect the 5838300626: DIFFERENTIAL HOUSING for wear or scoring, as housing distortion will quickly damage a new shim.

Frequently Asked Questions

Q: How do I verify the correct shim thickness for my ZF transmission?
A: Measure the actual clearance between the differential bearing outer race and the housing face using a depth micrometer. Subtract the desired preload (typically 0.05–0.15 mm) from that measurement to select the proper shim. The 0730.007.570 is a 1.50 mm shim; if your calculated value differs, choose the nearest available thickness from the ZF shim range.

Q: Can I reuse this shim during a rebuild?
A: No. ZF OEM shims are designed for single-use installation. The material compresses slightly during initial torque-down, and reusing it will result in incorrect preload. Always install a new 0730.007.570 shim and replace the 0750117075: TAPER ROLLER BEARING at the same time for consistent geometry.

Q: Will this shim fit a ZF WG180 transmission with a 4WD conversion?
A: Yes, the 0730.007.570 is compatible with standard WG180 differential housings. However, if your conversion uses a non-OEM 5838300626: DIFFERENTIAL HOUSING, verify the housing bore depth before ordering, as aftermarket housings may have different tolerances.
