ZF 0501.298.379 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.298.379 GASKET is a critical sealing component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits precisely between the transmission housing and the HOUSING assembly, preventing pressurized oil from escaping and maintaining the hydraulic integrity required for smooth gear engagement. The SKU 0501.298.379 is manufactured to ZF’s exacting tolerances, ensuring a leak-proof seal even under extreme thermal cycling and high-pressure operating conditions. Without this gasket, the transmission’s internal lubrication system cannot function correctly, leading to rapid component wear.

Symptoms of Failure

When the 0501.298.379 gasket degrades, operators typically notice these specific failure indicators:

• External oil seepage at the housing joint — visible drips or wet spots around the mating surface where the gasket sits, often accompanied by a burning smell.
• Intermittent gear slippage under load — as the gasket loses its seal, hydraulic pressure drops, causing clutches to slip during acceleration or hill climbs.
• Contaminated transmission fluid — a compromised gasket allows dirt and moisture to enter the system, turning the fluid dark or milky.
• Erratic shift timing — the transmission may delay or harshly engage gears due to inconsistent internal pressure from the failing seal.

Technical Specifications

Compatibility

This gasket is specifically designed for ZF’s WG-series powershift transmissions. It is a direct fit for the WG100, WG130, and WG131 models. While primarily intended for these three series, it may also be compatible with earlier WG180 and WG200 variants when used in conjunction with the correct MOTOR and COVER assemblies. Always verify the mating surface geometry before installation, as the TAPERED ROLLER BEARING preload can affect gasket compression.
