ZF 0730.112.809 SHIM | OEM Genuine Part

Overview

The ZF 0730.112.809 SHIM is a precision-engineered OEM genuine spacer component designed to establish critical axial clearances within heavy-duty ZF transmission assemblies. Positioned between gear sets and bearing races, this shim compensates for manufacturing tolerances and ensures correct preload on rotating elements. The SKU 0730.112.809 is commonly found in the differential housing section of construction machinery transmissions, where it directly influences gear mesh patterns and load distribution. By maintaining exact end-play specifications, this shim prevents excessive movement that can lead to premature wear on adjacent components such as the 2095109020: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Transmission whining noise during load shifts – A worn or collapsed 0730.112.809 shim allows the differential assembly to shift axially, creating a high-pitched metallic whine under torque. This is a common long-tail search query for “ZF transmission whining noise fix.”
• Oil seepage from differential housing gasket – Excessive clearance from a degraded shim forces the housing to flex, breaking the seal between the 2095309059: DIFF.HOUSING and the main case. This leads to visible oil leaks around the mating flange.
• Intermittent gear slipping under heavy load – When the shim thickness is reduced by wear, the 2095209037: DIFFERENTIAL loses proper preload, causing the bevel gears to momentarily disengage during high-torque operations.
• Vibration through the driveline at highway speeds – A misaligned shim creates an imbalance in the rotating differential assembly, transmitting vibrations that worsen with speed.

Technical Specifications

Compatibility

This shim is engineered for ZF heavy-duty powershift transmissions commonly used in construction machinery. It is a direct fit for the following transmission models: ZF WG180, ZF WG200, ZF WG210, and ZF WG250. The 0730.112.809 is also applicable in select ZF 4WG-200 and ZF 5WG-210 variants. Always verify the shim stack thickness against your service manual, as multiple shims may be stacked to achieve the specified end-play.
