ZF 0730.107.846 SHIM | OEM Genuine Part

Overview

The ZF 0730.107.846 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within heavy-duty ZF transmission assemblies. This thin, hardened steel spacer sits between rotating elements and the transmission housing, ensuring that gear stacks and shaft assemblies maintain their exact positional tolerances under extreme load. The SKU 0730.107.846 is specifically utilized in construction machinery transmissions to prevent metal-on-metal contact and to distribute clamping forces evenly across the bearing surfaces. When installed correctly alongside a 2094104412 MAIN SHAFT, this shim guarantees that the main shaft’s end-play remains within factory specifications, directly influencing overall drivetrain durability.

Symptoms of Failure

When the ZF 0730.107.846 SHIM becomes worn, crushed, or corroded, operators will notice distinct performance degradation. The most common failure symptoms include:

• Transmission oil seepage at the main shaft housing — A worn shim allows the shaft to shift axially, breaking the seal between the housing and the rotating assembly, leading to slow oil leaks that worsen over time.
• Intermittent gear slipping under load — Loss of correct shim thickness reduces preload on the bearing stack, causing the gear train to momentarily lose engagement when the machine is under heavy torque.
• Abnormal low-frequency vibration from the transmission bell housing — As the shim compresses unevenly, the main shaft develops a wobble that transmits through the entire driveline, particularly noticeable at idle and during deceleration.
• Hard shifting between forward and reverse — Insufficient shim height alters the alignment of the shift forks, making gear engagement feel notchy or requiring excessive force on the lever.

Compatibility

This shim is a standard fitment across ZF’s heavy-duty powershift transmission series used in construction machinery. It is directly compatible with the following ZF transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF 4WG-200
• ZF 5WG-200

In these transmissions, the 0730.107.846 shim is typically installed on the output side of the 2094304054 MAIN SHAFT and works in conjunction with the 2094106010 SHIFT SYSTEM to maintain correct fork-to-collar spacing. It also supports the alignment of the 2094206001 GEARSHIFT SHAFT by preventing lateral drift of the selector mechanism.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.107.846 shim during a transmission rebuild?
A: No. This shim is a single-use crush component. Once compressed during initial assembly, its thickness changes permanently. Always install a new OEM shim to maintain correct axial preload and prevent premature bearing failure.

Q: How do I know if the 0730.107.846 shim is the correct thickness for my application?
A: The shim thickness is fixed at 1.50 mm. However, in some WG200 transmissions, you may need to stack this shim with a thinner 0.50 mm shim (part 0730.107.845) to achieve the specified end-play of 0.08–0.15 mm. Always measure the clearance with a dial indicator during assembly.

Q: Will a worn shim cause damage to the main shaft?
A: Yes. A collapsed shim allows the 2094104412 MAIN SHAFT to hammer against the housing shoulder, leading to fretting wear on the shaft shoulder and potential cracking of the transmission case. Replace the shim immediately if you detect axial play.
