Overview
The ZF 0630.004.264 SHIM RING is a precision-engineered OEM genuine component designed for critical axial clearance management within heavy-duty ZF transmissions. This shim ring sits between the planetary gear set and the housing assembly, ensuring correct end-play tolerances are maintained under extreme load conditions. As a factory-spec part, the SKU 0630.004.264 guarantees exact fitment and material hardness to prevent premature wear. When paired with the 4108101057 HOUSING or the 4108201177 HOUSING, this shim ring provides the necessary preload to eliminate gear train vibration. Its role is non-negotiable in maintaining proper gear mesh depth and preventing thrust load damage to adjacent components.
Symptoms of Failure
- Transmission oil leaks at housing joint: A worn or collapsed shim ring allows the 4108301304 BEARING COVER to shift, breaking the seal surface and causing external fluid seepage.
- Gear slipping under load: Incorrect shim thickness reduces clutch pack clamping force, leading to intermittent power loss during acceleration or uphill operation.
- Abnormal whining noise from planetary section: Excessive axial play from a degraded shim ring causes gear tooth contact pattern deviation, producing a high-pitched metallic sound.
- Hard shifting or delayed engagement: Worn shims alter the hydraulic piston stroke, resulting in sluggish gear changes and increased shift shock.

Compatibility
This shim ring is primarily utilized in ZF WG180, WG200, and WG210 series powershift transmissions commonly found in construction machinery such as wheel loaders, graders, and telehandlers. It also applies to select ZF Ecomat 4HP and 5HP models where planetary gear end-play adjustment is required. Always verify the selective thickness range against your transmission’s service manual. For complete assembly, consider the 0636302056 SCREW PLUG which seals the adjustment access port, and the 4108301304 BEARING COVER that retains the shim in position.
