ZF 0730.108.404 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.404 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF transmissions used in construction machinery. This shim sits between the differential housing and bearing races, ensuring proper preload on the 0750117075: TAPER ROLLER BEARING assembly. By maintaining exact tolerances, the SKU 0730.108.404 prevents gear train misalignment and reduces internal stress on adjacent rotating assemblies. Its role is vital for load distribution across the 5838109007: DIFFERENTIAL unit, directly influencing torque transfer efficiency in wheel loaders and excavators.

Symptoms of Failure

• Excessive differential backlash during operation – A worn shim allows axial play, causing delayed engagement when shifting between forward and reverse gears.
• Metallic grinding noise from the transmission housing – Insufficient shim thickness leads to taper roller bearing slippage, producing a distinct scraping sound under load.
• Premature wear on companion components – A collapsed shim forces the 2095209019: DIFFERENTIAL to contact the housing, accelerating damage to both the carrier and the 0631329086: SPRING PIN retention system.
• Oil contamination with metallic particles – As the shim degrades, microscopic steel fragments circulate through the lubricant, clogging filters and scoring bearing surfaces.

Technical Specifications

Compatibility

This shim is engineered for ZF WG180, WG200, and WG310 series transmissions commonly installed in construction machinery such as Volvo L120 wheel loaders, Caterpillar 950G, and Komatsu WA380. It also fits select ZF Ecomat 5HP and 6HP models used in off-highway dump trucks. Always verify clearance requirements with a dial indicator before installation, as the 0.40 mm thickness is a baseline specification for standard differential preload setups.
