ZF 0730.107.845 SHIM | OEM Genuine Part

Overview

The ZF 0730.107.845 SHIM is a precision-engineered OEM genuine part designed to establish exact axial clearances within heavy-duty construction machinery transmissions. This thin, hardened steel component sits between rotating assemblies and housing surfaces, compensating for manufacturing tolerances to ensure optimal gear mesh and bearing preload. The SKU 0730.107.845 is critical for maintaining the structural integrity of the gear train, preventing unwanted movement that leads to premature wear. When paired with a 2094104412 MAIN SHAFT, this shim guarantees that the shaft remains perfectly aligned under extreme torque loads, reducing vibration and extending transmission life.

Symptoms of Failure

When the ZF 0730.107.845 SHIM wears or collapses, operators will notice distinct performance degradation. Excessive axial play in the drivetrain is the most common indicator, often felt as a clunking sensation during gear engagement. Oil leaks from the transmission housing can develop as the shim loses thickness, allowing the main shaft to shift and compromise seal contact. Gear slipping under load occurs because incorrect clearance prevents the shift system from fully engaging clutch packs. Finally, abnormal bearing noise—a high-pitched whine or grinding—signals that the shim has failed to maintain proper preload, leading to bearing race damage.

Technical Specifications

Compatibility

This shim is specifically engineered for ZF heavy-duty powershift transmissions commonly found in construction machinery. It is a direct fit for the ZF WG180, WG200, and WG210 series gearboxes. The 0730.107.845 is also used in select ZF 4WG-200 and 5WG-210 torque converter transmissions. For proper installation, this shim must be used in conjunction with the 2094304054 MAIN SHAFT and the 2094106010 SHIFT SYSTEM to ensure correct axial positioning of the gear train. Additionally, the 2094206001 GEARSHIFT SHAFT relies on precise shim thickness to prevent binding during fork movement.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.107.845 shim after disassembly?
A: No. This shim is a single-use component. Once compressed during initial assembly, it takes a set and will not provide accurate clearance if reinstalled. Always replace with a new OEM shim during transmission rebuilds.

Q: How do I measure the correct shim thickness for my WG200 transmission?
A: Use a depth micrometer to measure the distance from the bearing face to the housing shoulder, then subtract the desired end-play (typically 0.05–0.15 mm). The 0730.107.845 is 0.50 mm thick; stack multiple shims if needed, but never exceed two.

Q: Will a worn shim cause damage to the shift system?
A: Yes. Excessive axial play allows the main shaft to walk, misaligning the 2094106010 SHIFT SYSTEM forks. This leads to incomplete clutch engagement and eventual scoring of the gearshift shaft.
