ZF 0501.319.959 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.319.959 GASKET is a precision-engineered sealing component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits at critical interface points within the transmission housing, preventing fluid migration between the 4143101022 HOUSING and adjacent assemblies. The SKU 0501.319.959 ensures a leak-proof barrier that maintains hydraulic pressure integrity, directly supporting clutch engagement and gear shift quality. As a consumable sealing element, this gasket must be replaced during any major transmission overhaul to restore factory-specified tolerances.

Symptoms of Failure

• Transmission fluid seepage at housing joints – Visible oil streaks or puddling beneath the bell housing indicate the gasket has lost its compressive seal, often accompanied by a burnt smell from fluid contacting hot exhaust components.
• Erratic gear engagement or delayed shifts – When the gasket fails, hydraulic pressure drops inside the valve body, causing soft shifts or hesitation when moving from Park to Drive.
• Contaminated transmission fluid – A degraded gasket allows external debris or moisture to enter the system, turning the ATF a milky or dark color and accelerating internal wear.
• Whining or humming noise from transmission – Loss of seal integrity can introduce air into the hydraulic circuit, creating cavitation noise that worsens under load.

Technical Specifications

Compatibility

This gasket is engineered for ZF WG-series powershift transmissions, specifically the WG100, WG130, and WG131 models used in construction and agricultural machinery. It also fits select variants of the WG180 and WG200 series when installed between the 4143301044 HOUSING and the main gear case. Always verify the 0631329135 SPRING PIN alignment and 0636302014 SCREW PLUG torque specifications during installation to prevent gasket distortion.
