ZF 0730.112.622 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.622 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within ZF heavy-duty transmission assemblies. Positioned between the differential housing and bearing races, this shim compensates for manufacturing tolerances and ensures correct preload on gear sets. The SKU 0730.112.622 is a factory-specified part that directly controls gear mesh depth and backlash in construction machinery drivelines. Without this shim, the entire differential assembly—including the 2099109002 DIFFERENTIAL and 2099364014 CROWN WHEEL—cannot achieve proper rotational alignment.

Symptoms of Failure

• Excessive driveline backlash: A worn or incorrect shim causes noticeable clunking when shifting between forward and reverse, particularly in wheel loaders and graders.
• Premature crown wheel wear: Incorrect shim thickness forces the 2099209001 DIFFERENTIAL pinion to ride too deep or too shallow, accelerating tooth face pitting.
• Oil contamination from metal debris: As the shim collapses, the 2098309010 DIFFERENTIAL HOUSING experiences micro-movement, generating fine metallic particles in the transmission oil.
• Intermittent gear whine under load: A degraded shim alters the contact pattern between the crown wheel and pinion, producing a high-pitched noise during excavation or heavy hauling.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series. The 0730.112.622 also applies to select 4WG-200 and 6WG-200 variants used in articulated dump trucks and crawler dozers. Always verify the shim stack height against the differential housing bore depth when replacing the 2098309010 DIFFERENTIAL HOUSING or its alternate 2098309009 DIFFERENTIAL HOUSING.
