ZF 0501.320.242 GASKET for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.320.242 GASKET is a precision-engineered sealing component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits between the transmission housing and the valve body or cover plate, creating a critical barrier that prevents fluid migration and maintains internal pressure. The SKU 0501.320.242 ensures a factory-specification fit, directly replacing worn seals to restore hydraulic integrity. When paired with a new 4143101009 HOUSING or a 4143301025 HOUSING, this gasket guarantees a leak-free interface in high-torque industrial applications.

Symptoms of Failure

• External oil seepage at the housing joint: A degraded gasket allows transmission fluid to escape, often visible as wet spots around the mating surfaces of the WG100 or WG130.
• Erratic gear engagement or slipping: When the gasket fails, internal hydraulic pressure drops, leading to delayed shifts or clutch pack slippage under load.
• Contaminated fluid from external debris ingress: A compromised seal lets dirt and moisture enter the transmission, accelerating wear on components like the 0634313603 O-RING and valve bodies.
• Audible whining or hissing from the transmission: Air ingestion through a faulty gasket can cause cavitation, producing unusual noises during operation.

Technical Specifications

Compatibility

This gasket is specifically engineered for ZF WG100, WG130, and WG131 transmissions, commonly found in heavy-duty trucks, buses, and off-highway equipment. It also fits select variants of the WG180 and WG200 series when used in conjunction with the 4475280018 SCREW PLUG and proper torque specifications. Always verify your transmission model suffix before installation, as housing designs may vary by application year.
