ZF 0730.109.605 SHIM | OEM Genuine Part

Overview

The ZF 0730.109.605 SHIM (SKU: 0730.109.605) is a precision-engineered OEM genuine component designed for axial clearance adjustment within ZF heavy-duty transmissions. This shim sits between the main shaft assembly and the gearshift housing, ensuring correct preload on bearings and preventing unwanted axial movement of rotating elements. As a critical wear item in construction machinery transmissions, it maintains the exact spacing required for optimal gear mesh and load distribution. The 0730.109.605 shim works in concert with the 2094104412 MAIN SHAFT and the 2094304054 MAIN SHAFT to preserve drivetrain integrity under high torque loads.

Symptoms of Failure

• Transmission whining noise under load: A worn or collapsed 0730.109.605 shim allows excessive end-play, causing the main shaft to vibrate against the housing, producing a distinct metallic whine during acceleration.
• Oil seepage from the shift housing gasket: Incorrect shim thickness alters the housing alignment, leading to gasket distortion and slow oil leaks around the 2094106010 SHIFT SYSTEM interface.
• Hard shifting or gear engagement delay: When the shim wears unevenly, the 2094206001 GEARSHIFT SHAFT can bind, making gear selection stiff or requiring double-clutching.
• Vibration in neutral at idle: Loss of shim thickness allows the main shaft to oscillate, transmitting vibration through the shift linkage and into the cab.

Technical Specifications

Compatibility

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

• ZF WG180 (all variants)
• ZF WG200 (including WG200/2 and WG200/3)
• ZF WG210 (early production)
• ZF 4WG-200 (four-speed versions)

Always verify the shim stack thickness during rebuild. For complete main shaft overhaul, pair this shim with the 2094304054 MAIN SHAFT and inspect the 2094106010 SHIFT SYSTEM for wear.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. ZF recommends replacing all shims during a transmission overhaul because they are selective-fit components that can work-harden or deform. Always install a new OEM shim to maintain proper end-play specifications.”
