ZF 0730.102.102 SHIM | OEM Genuine Part

Overview

The ZF 0730.102.102 SHIM is a precision-engineered OEM genuine part designed for critical axial clearance adjustment within ZF heavy-duty powershift transmissions. This thin, hardened steel shim sits between the transmission housing and bearing races or gear faces, ensuring correct preload and end-play tolerances are maintained. The SKU 0730.102.102 is specifically used in construction machinery applications where vibration and thermal expansion demand exact spacing. By compensating for manufacturing tolerances, this shim prevents metal-to-metal contact and extends the service life of the entire gear train assembly.

Symptoms of Failure

• Excessive gear backlash or clunking during direction changes — When the shim wears or collapses, axial play increases, causing a noticeable “clunk” when shifting from forward to reverse.
• Premature bearing noise or whining — A worn shim allows the bearing outer race to move axially, generating a high-pitched whine that worsens under load.
• Oil contamination from metal debris — As the shim degrades, fine metallic particles enter the transmission fluid, often visible on the magnetic drain plug.
• Intermittent gear slipping under heavy load — Loss of correct shim thickness reduces clutch pack clamping force, leading to momentary power loss during excavation or grading.

Technical Specifications

Compatibility

This shim is engineered for ZF WG-series powershift transmissions commonly found in construction machinery. It is directly compatible with the ZF WG180, WG200, and WG210 models used in wheel loaders, graders, and telehandlers. The 0730.102.102 also fits select ZF Ergopower and Ecomat series where axial shimming of the input shaft or countershaft is required. Always verify stack height during rebuild.

Installation Context

During a transmission overhaul, the 0730.102.102 shim is installed adjacent to the 2094101012: TRANSMISSION HOUSING to set bearing preload. The shim sits between the housing face and the 2094301036: HOUSING component, which supports the planetary gear set. Correct shim selection is critical when replacing the 2094298057: HOUSING or the 2094301071: COVER, as these parts alter the axial stack tolerance. Always measure clearance with a dial indicator before final assembly.
