ZF 0730.108.073 SHIM | OEM Genuine Part

Overview

The ZF 0730.108.073 SHIM is a precision-engineered OEM genuine component designed to establish critical axial clearances within ZF powershift transmissions used in construction machinery. This shim sits between the main shaft assembly and the gearshift housing, compensating for manufacturing tolerances to ensure optimal gear engagement and load distribution. The SKU 0730.108.073 is specifically calibrated for high-torque applications, preventing metal-on-metal contact that accelerates wear. When installed alongside the 2094104412: MAIN SHAFT, this shim maintains the precise end-play required for smooth power transfer under heavy loads.

Symptoms of Failure

• Transmission end-play noise during deceleration: A dull thud or clunk when the machine slows indicates the shim has compressed beyond tolerance, allowing the main shaft to shift axially.
• Oil seepage from the shift housing gasket: Worn shims alter housing alignment, creating gaps that lead to hydraulic fluid leaks—a common issue in WG-series transmissions.
• Hard shifting or gear hang-up: When the 2094304054: MAIN SHAFT loses its shim-supported positioning, shift forks bind, causing delayed or incomplete gear changes.
• Vibration at the gearshift lever: Excessive axial play transmits through the 2094106010: SHIFT SYSTEM, producing noticeable vibration in the operator cab during operation.

Technical Specifications

Compatibility

This shim is engineered for ZF powershift transmissions commonly found in wheel loaders, dozers, and graders. Compatible models include the WG180, WG200, WG210, and WG250 series. It also fits the 4WG-200 and 6WG-200 variants used in construction machinery from manufacturers like Liebherr, Caterpillar (OEM cross-reference), and Volvo CE. Always verify the shim thickness against your transmission’s service manual, as the 2094206001: GEARSHIFT SHAFT requires precise shimming to prevent premature bushing wear.
