Overview
The ZF 2094.347.064 SCREW PLUG is a critical sealing component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part functions as a threaded closure within the transmission housing, preventing fluid leakage and maintaining hydraulic pressure integrity. Positioned at key access points in the drivetrain assembly, the SKU 2094.347.064 ensures that lubricants remain contained while allowing for maintenance access. Its precision-machined threads and robust construction make it indispensable for preserving the operational reliability of heavy-duty ZF gearboxes.
Symptoms of Failure
- Transmission fluid seepage around the housing: A worn or improperly seated screw plug often leads to visible oil leaks, especially after thermal cycling. This is a common search query for “ZF WG100 oil leak fix.”
- Contaminated lubricant causing gear slippage: When the plug fails, debris can enter the system, leading to “ZF transmission slipping under load” scenarios as hydraulic pressure drops.
- Increased noise from differential components: Loss of lubrication due to a compromised plug can cause “whining noise from ZF differential” as gears run dry.
- Difficulty maintaining transmission temperature: Low fluid levels from a leaking plug result in overheating, often searched as “ZF transmission running hot causes.”

Compatibility
This screw plug is specifically designed for ZF WG100, WG130, and WG131 transmission models. It also fits select variants of the WG180 and WG200 series where the housing design incorporates identical thread specifications. The part is commonly used in agricultural machinery, construction equipment, and heavy-duty trucks equipped with these ZF gearboxes. For differential assemblies, this plug works in conjunction with the 2094109002: DIFFERENTIAL and the 2052209109: DIFFERENTIAL HOUSING to ensure complete sealing. It also interfaces with the 2094209001: FLANGE and the 0731305002: GROOVED PIN in the same drivetrain assembly.
