ZF 0501.319.958 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.319.958 GASKET is an OEM genuine sealing component engineered for the WG100, WG130, and WG131 transmission series. This precision-formed gasket sits between the transmission housing and the valve body or cover plate, creating a leak-proof barrier that maintains hydraulic pressure integrity. The SKU 0501.319.958 is a direct replacement part designed to restore factory sealing performance, preventing fluid migration that can compromise shift quality. When installed alongside the 4143101022 HOUSING or the 4143301044 HOUSING, this gasket ensures a secure mating surface that withstands thermal cycling and vibration common in heavy-duty industrial applications.

Symptoms of Failure

When the ZF 0501.319.958 GASKET degrades, operators typically notice these specific failure indicators:

• External oil seepage around the housing joint – Visible wetness or drips at the gasket interface, often accompanied by a burnt fluid smell.
• Erratic gear engagement or delayed shifts – Loss of internal pressure due to gasket blow-by causes hesitation when selecting forward or reverse gears.
• Low transmission fluid level without visible external leaks – Internal weeping into adjacent cavities, requiring frequent top-offs between service intervals.
• Contaminated fluid with air bubbles – A compromised gasket allows air ingress, leading to foamy oil and reduced lubrication efficiency.

Technical Specifications

Compatibility

This gasket is specifically designed for the ZF WG100, WG130, and WG131 series powershift transmissions. It is also compatible with select variants of the WG180 and WG200 models where the housing interface dimensions match. For proper installation, always verify the mating surface condition of the 0631329135 SPRING PIN and the 0636302014 SCREW PLUG to ensure no debris compromises the seal. The gasket is not interchangeable with earlier WG series models without cross-referencing the housing part numbers.
