ZF 0501.319.957 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.319.957 GASKET is a precision-engineered sealing component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part ensures a leak-proof interface between the transmission housing and adjacent assemblies, preventing fluid migration and maintaining hydraulic pressure integrity. The SKU 0501.319.957 is critical for preserving the operational reliability of your ZF drivetrain, particularly when installed alongside the 4143101022 HOUSING and 4143301044 HOUSING, where it forms a primary static seal. Without this gasket, the transmission’s internal lubrication system cannot function correctly, leading to accelerated component wear.

Symptoms of Failure

When the 0501.319.957 gasket deteriorates, operators will notice distinct performance issues. Common failure indicators include:

• Oil seepage at housing mating surfaces — Visible fluid accumulation around the joint between the 4143101022 HOUSING and the transmission body, often mistaken for a cracked casing.
• Hydraulic pressure loss during gear engagement — A soft or delayed shift response, particularly under load, indicating internal fluid bypassing the gasket.
• Contaminated transmission fluid — Dirt or moisture ingress at the seal point, leading to sludge formation and reduced lubricity.
• Audible whining from the gear train — Insufficient fluid pressure causes cavitation in the valve body, producing a high-pitched noise during operation.

Technical Specifications

Compatibility

This gasket is specifically engineered for ZF WG100, WG130, and WG131 series transmissions. It is also compatible with the WG180 and WG200 models when used in conjunction with the 0631329135 SPRING PIN and 0636302014 SCREW PLUG for proper alignment. Always verify your transmission’s serial number before installation, as variations exist between early and late production units.
