ZF 0730.303.365 SHIM for WG92 | OEM Genuine Part

Overview

The ZF 0730.303.365 SHIM is a precision-engineered spacer component designed for critical axial clearance adjustment within the WG92 and WG98 series transmissions. This OEM genuine part, identified by SKU 0730.303.365, sits between the TRANSMISSION HOUSING and the HOUSING II assembly, ensuring correct preload and alignment of internal gear sets. By maintaining exact tolerances, this shim prevents unwanted movement that can lead to premature bearing wear and gear misalignment. Its role is fundamental to the structural integrity of the transmission’s main case.

Symptoms of Failure

• Excessive axial play or end float in the main shaft: When the 0730.303.365 shim compresses or wears, operators may notice a distinct clunking sound during gear engagement or load reversal.
• Intermittent gear slipping under heavy load: A worn shim allows the gear cluster to shift slightly, causing momentary loss of torque transfer, particularly in WG92 series units.
• Oil seepage at the housing joint: Incorrect shim thickness can distort the mating surface between the transmission housing and housing II, leading to slow oil leaks around the gasket area.
• Vibration at specific RPM ranges: Loss of proper shim support allows the countershaft to resonate, producing a low-frequency hum that intensifies with transmission temperature.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG92 and WG98 transmission families. It is directly compatible with the following models: WG92, WG98, WG120, WG150, WG180, and WG200 series. The part is specifically required when servicing the main bearing preload stack in units equipped with the CYLINDRICAL PIN alignment system. Always verify the existing shim thickness before replacement, as multiple thickness variants exist within the 0730.303.xxx range. The TYPE PLATE on your transmission housing will confirm the exact series designation.
