ZF 0730.108.395 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.395 SHIM is a precision-engineered spacer component designed to establish critical axial clearances within heavy-duty ZF powershift transmissions. Positioned between planetary gear sets and bearing races, this OEM genuine part ensures correct preload and alignment of rotating assemblies. The SKU 0730.108.395 is specifically utilized in construction machinery drivelines to prevent metal-on-metal contact and maintain optimal gear mesh patterns. Without this shim, transmission components cannot achieve the tight tolerances required for reliable torque transfer under extreme loads.

Symptoms of Failure

• Excessive gear backlash and clunking during direction changes – When the ZF 0730.108.395 shim wears or compresses beyond specification, gear lash increases, producing audible thuds when shifting from forward to reverse in wheel loaders or dozers.
• Premature differential bearing noise – A worn shim allows the 0750117075 TAPER ROLLER BEARING to lose preload, resulting in a low-frequency rumble or growl that intensifies under load during straight-line travel.
• Oil contamination from metal debris – As the shim fails, adjacent components like the 5838109007 DIFFERENTIAL may experience fretting wear, shedding metallic particles into the transmission fluid and clogging filters.
• Intermittent loss of drive in high torque applications – Insufficient shim thickness causes the 2095209019 DIFFERENTIAL to shift axially, momentarily disengaging clutch packs under heavy digging or pushing operations.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in construction machinery, specifically the WG180, WG200, and WG210 series. It is also applicable to certain variants of the 4WG-200 and 6WG-200 transfer cases used in articulated dump trucks and crawler excavators. Always verify the selective fit thickness (0.395 mm) against your transmission’s service manual, as adjacent components like the 0631329086 SPRING PIN must be correctly seated to prevent shim displacement during reassembly.
