ZF 0630.100.237 SPRING WASHER for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0630.100.237 SPRING WASHER is a precision-engineered OEM genuine component designed for the WG100, WG130, and WG131 transmission series. This critical fastener element sits within the planetary gear assembly, where it maintains consistent axial preload on the HOUSING and WHEEL SHAFT interfaces. By absorbing vibration and compensating for thermal expansion, the spring washer ensures that adjacent components—such as the PLANET CARRIER—remain securely clamped under high-torque conditions. The SKU 0630.100.237 is a direct replacement for the original factory part, guaranteeing exact dimensional tolerances and material hardness.

Symptoms of Failure

• Transmission gear slipping under load – A worn spring washer loses its clamping force, allowing the BASIC PARTS assembly to shift slightly, causing intermittent power loss during acceleration.
• Metallic rattling or clunking from the gearbox – When the washer fatigues, axial play develops between the planet carrier and housing, producing audible noise during deceleration or idle.
• Oil leaks near the output shaft seal – Excessive movement from a collapsed spring washer can distort the housing seal surface, leading to gradual fluid seepage.
• Premature bearing wear – Loss of preload forces the wheel shaft to operate with excessive clearance, accelerating bearing degradation and reducing transmission lifespan.

Technical Specifications

Compatibility

This spring washer is engineered for the following ZF transmission models: WG100, WG130, and WG131. It is also compatible with select WG180 and WG200 variants that share the same planetary carrier architecture. Always verify your transmission serial number against the OEM parts catalog before ordering.
