ZF 0730.109.572 SHIM | OEM Genuine Part

Overview

The ZF 0730.109.572 SHIM is a precision-engineered OEM genuine component designed to maintain critical axial clearances within heavy-duty ZF powershift transmissions. This shim sits between the main shaft assembly and the gearshift housing, compensating for manufacturing tolerances and preventing unwanted end-play that can lead to drivetrain inefficiency. As a wear-and-set component, the SKU 0730.109.572 ensures that the 2094104412 MAIN SHAFT and the 2094304054 MAIN SHAFT remain correctly positioned under load, reducing vibration and extending the service life of the entire transmission assembly.

Symptoms of Failure

When the ZF 0730.109.572 shim wears or collapses beyond its service limit, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Excessive axial play in the main shaft — A worn shim allows the main shaft to move fore and aft, producing a distinct clunking noise during gear engagement.
• Intermittent gear slipping under load — Loss of correct shim thickness reduces clutch pack preload, causing the transmission to slip when climbing grades or hauling heavy loads.
• Oil seepage at the shift housing interface — Increased shaft movement distorts the housing seal, leading to slow oil leaks that contaminate the bell housing.
• Hard shifting or gear clash — Incorrect axial positioning of the 2094106010 SHIFT SYSTEM results in delayed or rough shifts, especially between forward and reverse ranges.

Compatibility

This shim is engineered for ZF powershift transmissions commonly used in construction machinery. It is a direct fit for the following transmission models:

• ZF WG180 (all series)
• ZF WG200 (all series)
• ZF WG210 (early production)
• ZF 4WG-200 / 4WG-210

When replacing the shim, always inspect the mating 2094206001 GEARSHIFT SHAFT for scoring or wear, as a damaged shaft will quickly destroy a new shim.

Frequently Asked Questions

Q: Can I reuse the old shim if it looks undamaged?
A: No. ZF shims are designed as single-use crush or selective-fit components. Even if the shim appears intact, its thickness may have changed due to micro-compression. Always replace the 0730.109.572 shim with a new OEM part when overhauling the main shaft area.

Q: How do I measure the correct shim thickness for my transmission?
A: Use a dial indicator to measure the end-play of the main shaft after installing the 2094104412 MAIN SHAFT without the shim. Subtract the desired clearance (typically 0.05–0.15 mm) from the measured gap, then select the shim thickness that matches that value. ZF supplies shims in 0.05 mm increments.

Q: Will a worn shim cause damage to the shift system?
A: Yes. Excessive axial play forces the 2094106010 SHIFT SYSTEM to operate outside its designed alignment, leading to premature wear of shift forks, detent springs, and the 2094206001 GEARSHIFT SHAFT. Replace the shim at the first sign of gear clash.
