ZF 0730.005.319 SHIM for WG65 | OEM Genuine Part

Overview

The ZF 0730.005.319 SHIM is a precision-engineered spacer component designed for the WG65 series of heavy-duty transmissions. This OEM genuine part sits between the TRANSMISSION HOUSING and the clutch pack assembly, where it controls axial clearance and ensures correct preload on rotating elements. By maintaining exacting tolerances, the SKU 0730.005.319 prevents metal-to-metal contact and reduces vibration during gear shifts. This shim is critical for extending the service life of the entire drivetrain, as even minor deviations in clearance can lead to accelerated wear on adjacent components.

Symptoms of Failure

• Persistent oil leaks around the housing joint – When the shim compresses or corrodes, the seal between the HOUSING and the main case fails, causing fluid seepage.
• Gear slipping under load – Worn shim thickness reduces clutch pack clamping force, leading to intermittent power loss during acceleration.
• Metallic rattling from the transmission bell housing – Excessive axial play from a degraded shim allows gear teeth to clash, producing a distinct knocking sound at idle.
• Hard shifting between forward and reverse – Incorrect shim stack height alters hydraulic pressure timing, resulting in delayed or jerky engagement.

Technical Specifications

Compatibility

This shim is specifically engineered for the ZF WG65 series, including models WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is used in both on-highway truck transmissions and off-highway industrial gearboxes. The 0730.005.319 is also compatible with certain ZF Ecomat and Ecolife variants that share the same clutch housing architecture. Always verify clearance requirements with your service manual before installation.
