ZF 0730.100.079 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.100.079 SHIM is a precision-engineered adjustment component designed specifically for the WG65 series of heavy-duty transmissions. This OEM genuine part functions as a critical spacer within the planetary gearset assembly, ensuring correct axial clearance between rotating and stationary components. By maintaining precise end-play tolerances, the shim prevents unwanted metal-to-metal contact that can lead to premature wear. The SKU 0730.100.079 is manufactured to ZF’s exacting specifications, guaranteeing a perfect fit when paired with the 4616105413: OUTPUT and the 4616203017: OUTPUT FLANGE during rebuild or repair procedures.

Symptoms of Failure

• Excessive axial play in the output shaft – When the 0730.100.079 shim wears or compresses beyond tolerance, operators may notice a distinct clunking sensation during gear engagement or load reversal.
• Low-frequency vibration under load – A worn shim allows the gearset to shift out of alignment, generating a deep rumble that intensifies as transmission temperature rises.
• Premature seal failure at the housing interface – Incorrect shim thickness places stress on the 4616101117: TRANSMISSION HOUSING, leading to oil seepage around the output flange area.
• Intermittent gear slipping during torque conversion – Loss of proper shim clearance reduces clutch pack clamping force, causing momentary power loss under heavy acceleration.

Technical Specifications

Compatibility

This shim is engineered for the ZF WG65 transmission series, which includes models such as WG65, WG80, WG120, WG150, WG180, and WG200. It is commonly used in off-highway vehicles, wheel loaders, and industrial machinery where the WG65 planetary gearset is deployed. Always verify the selective fit requirement by measuring the stack height with the 0636011038: HEXAGON SCREW and associated fasteners during assembly.
