ZF 0730.301.795 SHIM | OEM Genuine Part

Overview

The ZF 0730.301.795 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF transmissions. Positioned between the differential housing and bearing races, this shim compensates for manufacturing tolerances, ensuring optimal gear mesh and load distribution. The SKU 0730.301.795 is a factory-specified spacer that prevents unwanted movement in the planetary gearset, directly influencing torque transfer efficiency in construction machinery drivelines. Without this shim, internal components like the 5838109007: DIFFERENTIAL cannot maintain proper alignment, leading to accelerated wear across the assembly.

Symptoms of Failure

• Excessive end-play in the differential carrier: A worn or collapsed shim allows axial movement, causing a distinct “clunk” during load reversals. This is a common search query for “ZF transmission differential play symptoms.”
• Premature taper roller bearing failure: When the 0730.301.795 loses its calibrated thickness, the 0750117075: TAPER ROLLER BEARING experiences uneven preload, generating heat and metallic debris. Operators often search for “taper bearing noise after rebuild.”
• Oil contamination from gear misalignment: Incorrect shim stack height forces the 2095209019: DIFFERENTIAL to run off-center, grinding against the housing and shedding metal particles into the hydraulic circuit.
• Intermittent gear slipping under load: As the shim compresses, the 0631329086: SPRING PIN that retains shift components can shear, leading to sudden power loss in excavators or wheel loaders.

Technical Specifications

Compatibility

This shim is a standard service part across multiple ZF heavy-duty transmission platforms. It is directly compatible with the WG180, WG200, and WG210 series used in articulated dump trucks and graders. Additionally, it fits the Ecomat 4HP and 6HP series when used in construction machinery applications. Always verify the shim stack count during rebuilds, as multiple 0730.301.795 units are often stacked with 5838300817: THRUST WASHER to achieve precise end-play specifications.
