ZF 0730.009.586 SHIM | OEM Genuine Part

Overview

The ZF 0730.009.586 SHIM is a precision-engineered OEM genuine part designed to establish critical axial clearances within ZF heavy-duty transmission assemblies. This thin, hardened shim sits between the transmission housing and bearing races or gear faces, compensating for manufacturing tolerances and preventing unwanted end-play. As a wear-adjustment component, it ensures that rotating elements maintain correct preload under high torque loads in construction machinery. The SKU 0730.009.586 is a factory-specified shim, not a generic substitute, guaranteeing exact thickness and flatness for reliable load distribution.

Symptoms of Failure

When the 0730.009.586 shim becomes worn, crushed, or corroded, several distinct failure modes emerge. Transmission gear slipping under load is a primary indicator, as lost axial clearance allows gears to drift out of mesh. Excessive driveline vibration during acceleration often follows, caused by bearing preload loss. Metallic debris in the transmission oil filter signals that the shim has fractured, allowing hardened particles to circulate. Finally, intermittent clutch pack engagement failure can occur when shim wear alters the stack height, preventing proper piston travel.

Technical Specifications

Compatibility

This shim is engineered for use in ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and graders. It is also compatible with certain ZF 4WG-200 and 6WG-200 variants used in articulated dump trucks. The shim is typically installed during rebuilds of the main drive shaft or output shaft bearing stacks. For precise fitment, always verify the shim thickness against the original stack height using a micrometer.

During installation, the 0730.009.586 shim is often paired with the 4695101002 HOUSING to set the initial bearing preload. The 4695301021 HOUSING and 4695301022 COVER enclose the shim and bearing assembly, while a new 0634801038 SEALING RING is critical to prevent oil bypass around the shim pocket. Always replace these companion components during a full transmission overhaul to ensure proper sealing and alignment.
