ZF 4616.303.049 SPRING WASHER for WG65 | OEM Genuine Part

Overview

The ZF 4616.303.049 SPRING WASHER is a critical OEM genuine component engineered for the WG 65 Series transmission. This precision-machined washer maintains consistent clamping force on fasteners within the gear train assembly, preventing loosening caused by thermal expansion and vibration. Specifically designed for the WG65, the SKU 4616.303.049 sits between the 4616105415: OUTPUT and the 4616303144: OUTPUT FLANGE, ensuring axial retention of the output shaft assembly. Its spring steel construction provides the necessary elasticity to absorb shock loads during gear shifts, directly protecting the 4616101094: TRANSMISSION HOUSING from stress fractures.

Symptoms of Failure

• Output shaft end-play and gear slipping: When the spring washer loses tension, the output shaft develops axial play, causing intermittent gear engagement loss under load.
• Abnormal driveline vibration at highway speeds: A worn 4616.303.049 cannot dampen harmonics, leading to noticeable shuddering through the chassis during 5th and 6th gear operation.
• Oil seepage around the output flange: Loss of clamping force allows the output flange seal to shift, creating slow leaks that contaminate the bell housing.
• Metallic rattling during deceleration: A fatigued spring washer permits loose hexagon screw connections, producing a distinct rattle when engine braking occurs.

Technical Specifications

Compatibility

This OEM genuine spring washer is specifically validated for the ZF WG 65 Series transmission family. It is directly compatible with the following ZF models: WG65, WG80, WG120, WG180, and WG200. The 4616.303.049 also fits select ZF Ecolife and AS Tronic variants that share the same output shaft architecture. Always verify the transmission housing casting number and hexagon screw torque specifications before installation.
