ZF 0730.102.063 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.102.063 SHIM is a precision-engineered adjustment component designed specifically for the WG 65 series heavy-duty transmission. This OEM genuine part, identified by SKU 0730.102.063, sits between the transmission housing and the bearing assembly to control axial play and preload tolerances. By maintaining exact clearance specifications, this shim prevents excessive movement of rotating assemblies, ensuring optimal gear mesh alignment and load distribution. It is typically installed during rebuilds or when replacing adjacent components such as the 2094101012: TRANSMISSION HOUSING or the 2094301036: HOUSING to restore factory-specified endplay.

Symptoms of Failure

• Excessive axial play in the output shaft: When the shim wears or compresses beyond tolerance, you may detect noticeable fore-aft movement in the driveline, leading to “ZF transmission output shaft endplay” issues.
• Intermittent gear slipping under load: Worn shims allow bearing migration, causing misalignment that results in “WG65 gear slipping during acceleration” complaints.
• Low-frequency bearing hum or growl: As preload is lost, bearings can skid or chatter, producing a distinct “transmission bearing noise after rebuild” symptom.
• Oil contamination from metal particles: Accelerated wear between the shim and adjacent 2094298057: HOUSING can generate fine metallic debris visible in the fluid.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG 65 series, including models such as WG65, WG80, WG120, WG150, WG180, and WG200. It is also compatible with select off-highway transmissions in the Ecolife and Ecomid ranges that share the same bearing bore geometry. Always verify the stack height requirement when pairing this shim with the 2094301071: COVER assembly, as multiple shims may be required to achieve correct preload.
