ZF 0730.000.531 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.000.531 SHIM is a precision-engineered spacer component designed for the WG 65 series of heavy-duty transmissions. This OEM genuine part sits between the TRANSMISSION HOUSING and the planetary gear set, where it controls axial clearance and preload. By maintaining exacting tolerances, the shim ensures that gear mesh patterns remain within factory specifications, preventing premature wear on bearings and clutches. The SKU 0730.000.531 is laser-etched for traceability, guaranteeing that you receive a genuine ZF component for your rebuild or repair.

Symptoms of Failure

When the 0730.000.531 shim wears or deforms, it can cause several distinct operational issues. Look for these specific failure symptoms:

• Excessive axial play in the output shaft – A worn shim allows the shaft to move back and forth, creating a knocking sound during gear changes.
• Oil leaks from the transmission housing joint – Incorrect shim thickness distorts the seal surface, leading to fluid seepage around the HEXAGON SCREW fasteners.
• Gear slipping under load – When axial clearance exceeds 0.15 mm, clutch packs fail to engage fully, causing power loss on inclines.
• Vibration at highway speeds – A deformed shim creates uneven gear contact, transmitting harmonics through the driveline.

Technical Specifications

Compatibility

This shim is specifically designed for the ZF WG 65 series of powershift transmissions. Based on its dimensions and application, it is compatible with the following models: WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is also used in certain off-highway variants like the WG65-2 and WG65-3. Always verify your transmission serial number before ordering. The shim works in conjunction with the HEXAGON SCREW and HEXAGON SCREW fasteners that secure the housing assembly.
