ZF 0730.109.182 SHIM | OEM Genuine Part

Overview

The ZF 0730.109.182 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within ZF heavy-duty powershift transmissions. This thin, hardened steel component sits between the transmission housing and bearing assemblies, compensating for manufacturing tolerances to ensure optimal gear mesh and load distribution. The SKU 0730.109.182 is commonly utilized in construction machinery applications, where it directly supports the planetary gear sets and shaft alignments. Without this shim, internal components can shift under load, leading to premature wear. It is often replaced alongside the 4108101127: HOUSING and 4108201277: HOUSING during a full transmission rebuild to restore factory-specified endplay.

Symptoms of Failure

• Excessive axial play in the output shaft: When the shim 0730.109.182 compresses or wears, you may feel a distinct clunk or movement when rotating the driveline by hand, indicating lost preload.
• Low-frequency gear whine under load: A worn shim allows the planetary carrier to drift, causing misaligned tooth contact that produces a constant, low-pitched whine during operation.
• Intermittent clutch pack slippage: If axial clearance increases beyond specification, hydraulic clutch packs may not fully engage, leading to erratic shifting or power loss under heavy torque.
• Metallic debris in transmission oil: As the shim degrades, fine steel particles can contaminate the fluid, often first noticed during routine oil analysis or when draining the sump.

Technical Specifications

Compatibility

This shim is primarily specified for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, graders, and material handlers. It also fits select variants of the ZF 4WG-200 and 6WG-200 models used in construction machinery. Always verify the part number against your transmission’s serial plate, as shim thickness may vary by application. For a complete rebuild, pair this shim with the 4108301304: BEARING COVER and 4108306173: GASKET to ensure a sealed, correctly preloaded assembly.
