ZF 0730.007.982 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.982 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within ZF heavy-duty transmission assemblies. Positioned between planetary gear sets and bearing races, this shim compensates for manufacturing tolerances, ensuring optimal gear mesh and load distribution. The SKU 0730.007.982 is specifically calibrated for use in construction machinery transmissions, where even micron-level misalignment can lead to premature wear. By maintaining exact end-play specifications, this shim protects adjacent components such as the 2095109016: DIFFERENTIAL and 2095209037: DIFFERENTIAL from axial stress.

Symptoms of Failure

• Transmission gear slipping under load: A worn or collapsed shim allows excessive axial play, causing gear teeth to lose proper contact, particularly in WG-series transmissions.
• Metallic grinding noise from differential housing: When the shim degrades, the 0750117075: TAPER ROLLER BEARING loses preload, resulting in audible bearing chatter during deceleration.
• Oil contamination with metallic particles: Shim failure permits contact between the 2095309059: DIFF.HOUSING and rotating gears, generating fine steel debris in the lubricant.
• Intermittent driveline vibration: Uneven shim wear creates harmonic imbalances that resonate through the axle assembly at specific RPM ranges.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly deployed in construction machinery. It is a direct fit for the following transmission models: WG180, WG200, WG210, WG250, and WG310. These units are found in wheel loaders, excavators, and telehandlers from manufacturers such as Liebherr, Caterpillar, and Volvo CE. The 0730.007.982 is also used in certain ZF ErgoPower and Ecolife series transmissions where differential preload adjustment is required.
