ZF 0730.007.956 SHIM | OEM Genuine Part

Overview

The ZF 0730.007.956 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF transmissions. This thin, hardened steel spacer sits between planetary gear sets and housing shoulders, ensuring correct preload on bearings and gear alignment. By maintaining exact tolerances, the 0730.007.956 prevents unwanted movement that leads to premature wear. As a factory-spec shim, it is essential for rebuilds of construction machinery transmissions, particularly when paired with a 2095109016 DIFFERENTIAL assembly. The SKU 0730.007.956 is laser-etched for traceability, guaranteeing it meets ZF’s original dimensional and metallurgical standards.

Symptoms of Failure

• Excessive gear backlash and clunking: When the 0730.007.956 shim compresses or wears, axial play increases, causing audible clunks during direction changes or load shifts.
• Premature bearing failure: Incorrect shim thickness leads to improper preload on the 0750117075 TAPER ROLLER BEARING, generating heat and spalling that shortens bearing life.
• Oil contamination from metal debris: A worn shim flakes microscopic steel particles into the transmission fluid, visible as glitter in oil samples or on magnetic drain plugs.
• Intermittent gear slipping under load: Loss of axial retention allows the 2095209037 DIFFERENTIAL to shift slightly, breaking torque transfer momentarily during heavy excavation.

Technical Specifications

Compatibility

This shim is a standard adjustment component in ZF’s heavy-duty transmission series used in construction machinery. It is commonly specified for the WG180, WG200, and WG250 models, as well as the 4WG-200 series. The 0730.007.956 is also found in certain ErgoPower and Ecolite transmissions where precise axial shimming of the 2095309059 DIFF.HOUSING is required. Always verify stack height during rebuild; this shim is often used in combination with other thicknesses to achieve final clearance.
