Overview
The ZF 2094.303.006 COVER is a critical sealing and protective component designed for heavy-duty construction machinery transmissions. This OEM genuine part sits on the exterior housing of the transmission assembly, providing a secure barrier that prevents contaminants from entering the gear train while retaining essential lubricants. As a structural element, the cover also supports alignment for adjacent rotating assemblies. The SKU 2094.303.006 is precision-engineered to ZF’s original specifications, ensuring a perfect fit and long service life in demanding off-highway applications.
Symptoms of Failure
When the ZF 2094.303.006 COVER begins to wear or sustain damage, operators may notice several distinct failure indicators. Oil seepage or active fluid leaks around the transmission housing are the most common early warning signs, often appearing as wet spots on the exterior casing. Increased gear noise or whining can develop if the cover loses its structural integrity, allowing vibration to transmit through the drivetrain. Contaminated transmission fluid may occur if the cover’s seal fails, permitting dirt and moisture to enter the system. In severe cases, erratic shifting or delayed engagement can result from pressure loss within the transmission circuit.

Compatibility
This cover is engineered for use in ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It is directly compatible with ZF WG180, WG200, and WG220 transmission models. The 2094.303.006 COVER also integrates with earlier generation ZF 4WG-200 and 5WG-200 series units. For optimal performance, this cover should be installed alongside the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, which support the internal gear mesh. Additionally, the 2093209023: DIFFERENTIAL and 5838300626: DIFFERENTIAL HOUSING are frequently replaced during the same service interval to ensure complete drivetrain reliability.
