ZF 0730.107.847 SHIM | OEM Genuine Part

Overview

The ZF 0730.107.847 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF powershift transmissions. This thin, hardened steel shim sits between the main shaft assembly and the gear train, compensating for manufacturing tolerances to ensure optimal gear mesh and load distribution. The SKU 0730.107.847 is specifically used in construction machinery applications, where it prevents metal-to-metal contact and maintains the preload required for smooth torque transfer. Without this shim, the transmission’s internal components would experience excessive end-play, leading to accelerated wear on the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT.

Symptoms of Failure

When the ZF 0730.107.847 shim wears or deforms, it triggers distinct operational issues that are easily identifiable during routine maintenance. The most common failure symptoms include:

• Axial shaft play and gear rattle: A worn shim allows the main shaft to drift axially, producing a metallic clattering noise during deceleration or idle, especially in WG-series transmissions.
• Oil contamination from metal debris: As the shim degrades, fine steel particles enter the hydraulic circuit, causing premature wear on the 2094106010: SHIFT SYSTEM and clogging valve bodies.
• Intermittent gear slipping under load: Loss of correct shim thickness reduces clutch pack clamping force, leading to momentary power loss when the machine is under heavy strain.
• Increased operating temperature: Excessive end-play forces the 2094206001: GEARSHIFT SHAFT to work harder, generating friction and heat that degrades transmission fluid faster.

Technical Specifications

Compatibility

This shim is primarily used in ZF’s heavy-duty powershift transmission families designed for construction machinery. It is a direct fit for the following models: WG180, WG200, WG210, and WG250. It also appears in certain iterations of the 4WG-200 and 5WG-210 series used in wheel loaders, dozers, and graders. Always verify the shim stack thickness during rebuild, as the 0730.107.847 is often paired with additional shims to achieve the specified end-play of 0.05–0.15 mm.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.107.847 shim during a transmission rebuild?
A: No. This shim is a selective-fit component that deforms plastically under load. Always replace it with a new OEM part to restore correct axial clearance and prevent damage to the main shaft and shift system.

Q: How do I measure the correct shim thickness for my WG200 transmission?
A: Use a dial indicator to measure the total end-play of the main shaft assembly. Subtract the measured play from the target specification (typically 0.05–0.15 mm) to determine the required shim thickness. The 0730.107.847 is 0.50 mm thick and can be stacked with other shims if needed.

Q: What happens if I install a shim that is too thick?
A: An oversized shim will preload the bearings excessively, causing rapid overheating and seizure of the 2094104412: MAIN SHAFT. This can lead to catastrophic transmission failure within hours of operation.
