ZF 0730.005.320 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.005.320 SHIM is a precision-engineered adjustment component designed specifically for the WG 65 series heavy-duty transmissions. This OEM genuine part, identified by SKU 0730.005.320, functions as a critical spacer within the planetary gearset assembly, ensuring correct axial clearance between rotating elements. By maintaining exact tolerances, this shim prevents metal-to-metal contact between the gear train and the TRANSMISSION HOUSING, directly influencing shift quality and torque transfer efficiency. Without this component, the entire gear stack can shift out of alignment, leading to premature wear across the drivetrain.

Symptoms of Failure

When the ZF 0730.005.320 SHIM wears or becomes damaged, operators will notice distinct performance degradation. Common failure indicators include:

• Persistent axial gear clatter during low-speed maneuvering, indicating excessive end-play in the planetary set.
• Intermittent gear slipping under load, particularly when climbing grades or hauling heavy payloads, as the shim loses its ability to maintain proper spacing.
• Metallic debris in transmission fluid during routine oil changes, a direct result of fretting wear between the shim and adjacent components like the HOUSING.
• Oil weeping from the output flange area, caused by vibration-induced misalignment that compromises seal integrity.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG 65 series transmission family, including models WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is a direct fit for all WG65 variants produced after 1998. The part interfaces directly with the HOUSING and is secured using HEXAGON SCREW fasteners during reassembly. Always verify the shim stack height using a dial indicator before final torquing of the housing bolts.
