ZF 0730.104.994 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.104.994 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission. This hardened steel washer functions as a critical load-spreading interface within the planetary gearset assembly, ensuring correct axial clearance and preventing metal-on-metal contact between rotating elements. As an authentic ZF part, the SKU 0730.104.994 guarantees exact dimensional tolerances required for reliable torque transfer and long service life. This washer is typically installed during a transmission overhaul alongside the 4460115043: HOUSING and the 4469315012: AXLE DRIVE HOUSING to restore factory-spec clearances.

Symptoms of Failure

• Transmission oil leaks at the output flange: A worn 0730.104.994 washer can cause misalignment, leading to seal failure and fluid seepage around the housing joint.
• Gear slipping under load: When the washer loses its original thickness, axial play increases, resulting in intermittent power loss during acceleration or hill climbing.
• Unusual whining or grinding noise from the transmission: Excessive clearance from a compressed washer allows gear teeth to contact improperly, generating metallic sounds during operation.
• Vibration in the driveline at highway speeds: A deformed washer disrupts bearing preload, causing driveline shudder that worsens with RPM changes.

Technical Specifications

Compatibility

This ZF 0730.104.994 washer is engineered for the WG 200 series transmissions, including models WG180, WG200, and WG210. It is also compatible with certain ZF Ecomat 4HP and 5HP variants that share the same planetary carrier architecture. For proper installation, always pair this washer with a new 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING to maintain correct preload specifications.
